'Candidatus phytoplasma phoenicium' sp. nov., a novel phytoplasma associated with an emerging lethal disease of almond trees in Lebanon and Iran.

Almonds (Prunus amygdalus) represent an important crop in most Mediterranean countries. A new and devastating disease of almond trees in Lebanon was recently reported, characterized by the development of severe witches'-brooms on which no flowers or fruits developed, and leading to tree death within a few years. A phytoplasma was detected in diseased trees by PCR amplification of rRNA operon sequences, and RFLP patterns of amplified DNA indicated that the phytoplasma belonged to the pigeon pea witches'-broom (PPWB) group. In the present work, the presence of a phytoplasma in symptomatic plants was confirmed by electron microscopy; this phytoplasma was graft-transmissible to almond, plum and peach seedlings. The phytoplasma was characterized by sequence analysis of rRNA genes and was shown to be different from the phytoplasmas previously described in the PPWB group. A 16S rDNA phylogenetic tree identified the almond tree phytoplasma as a member of a distinct subclade of the class Mollicutes. Oligonucleotides have been defined for specific detection of the new phytoplasma. The almond phytoplasma from Lebanon was shown to be identical to a phytoplasma that induces a disease called 'almond brooming' in Iran, but different from another PPWB-group phytoplasma that infects herbaceous annual plants in Lebanon. Based on its unique properties, the name 'Candidatus Phytoplasma phoenicium' is proposed for the phytoplasma associated with almond witches'-broom in Lebanon and Iran.

Ochratoxin A levels in human plasma and foods in Lebanon.

Ochratoxin A (OTA) is a widespread mycotoxin which contaminates food such as cereals, beer, coffee, wine and products of animal origin. OTA is known for its nephrotoxic, immunotoxic and carcinogenic properties. The prevalence of OTA in human blood and foodstuffs has been investigated in many countries. In this study, exposure of the Lebanese population to OTA was evaluated and the contamination of the most commonly consumed foods in Lebanon by OTA was assessed. Plasma samples from healthy individuals and also cereals and beer samples obtained from markets were collected from the different regions of Lebanon. OTA was detectable in 33% of tested plasma samples (n =250) with a concentration ranging from 0.1 to 0.87 ng/mL and a mean of 0.17+/-0.01ng/mL. No sex and age differences were found. The frequency of OTA-positive plasma samples obtained in the South of Lebanon and in the Bekaa valley (50 and 47%, respectively) was significantly higher compared to plasma samples obtained in the Beirut/Mount Lebanon region (19%). Food analyses showed that wheat, burghul and beer were contaminated with a mean value of 0.15+/-0.03 microg/kg, 0.21+/-0.04 microg/kg and 0.19+/-0.12 ng/mL, respectively. These data suggest that the Lebanese population is exposed to OTA through food ingestion at concentrations lower than the tolerable daily intake.

What does the World Health Report 2000 bring to Lebanon?

The World Health Report 2000 has been the subject of extensive debate. The authors highlight in the following, what they consider as major limitations that are either inherent to methods followed and the validity of data used, or related to the particular situation of Lebanon. This article tackles the first two of the set goals i.e. level of health and responsiveness as well as the overall system performance. The Report clearly states that extensive use has been made of estimates of indicators, and that there were often conflicting sources of information on these indicators. In the case of Lebanon, data was not available for most of the values used. In fact, the last national population census was conducted in 1932, and vital registration is incomplete. Therefore, one would question the value of the estimates, based on which the calculations were made for Lebanon, such as Life tables, and Causes of Deaths. Finally, the authors conclude that despite the critics, embarking in this exercise is useful for Lebanon, particularly at this stage, for monitoring the reform process in the health sector.

Intestinal parasites among presumably healthy individuals in Lebanon.

OBJECTIVE: To determine the prevalence period of intestinal parasites among presumably healthy subjects in Lebanon. METHODS: One stool specimen from 2634 presumably healthy Lebanese subjects, mean age 32.1 years with a range of 14-71 years, resident of different areas in Lebanon was examined for the presence of parasites. The analysis took place in the Clinical Microbiology Laboratory, Department of Pathology and Laboratory Medicine, American University of Beirut Medical Center, Beirut, Lebanon, over 25-months between 1995-1997. RESULTS: The prevalence of intestinal parasites was 12.4%. The most common parasites identified were Entamoeba coli (38%), Giardia lamblia (3.1%) and Entamoeba histolytica (2.3%) [corrected]. CONCLUSION: The data presented shows the need to improve hygienic conditions to contain the problem of intestinal infections with parasites in Lebanon.

Lebanon's health care policy: a case study in the evolution of a health system under stress.

Lebanon's experience in the development of its health care system over the last century is reviewed; inasmuch as experiences can be generalizable, the case of Lebanon reflects the attempts of middle-income countries to balance the public and private sectors' roles in health care. Lebanon's health care system followed a predictable trend that was accelerated and intensified by the civil disturbances during the past decade. Its main feature has been the absence of a coherent and sustained health policy that promotes a stable and long-lasting relationship between the public and the private sectors in health. The role of the State has been most effective during periods of political, social and economic stability, when serious planning efforts could be undertaken and resultant policies be implemented. An effective partnership between the State and the private sector is recommended for the reconstruction of Lebanon's health care system, as well as for other countries with a strong private sector involvement in health care.

Destruction of Escherichia coli O157:H7 and Salmonella typhimurium in Lebanon bologna by interaction of fermentation pH, heating temperature, and time.

Fermented meats have caused food-borne illness due to enterohemorrhagic Escherichia coli. Consumption of Lebanon bologna was epidemiologically associated wit a recent outbreak of salmonellosis. The present study was conducted to determine the effect of pH (after the fermentation step), final heating temperature, and time on destruction of E. coli O157:H7 and Salmonella typhimurium in Lebanon bologna. Raw Lebanon bologna mix was inoculate with either of the pathogens (ca.10(8) CFR/g and fermented for 12 h at 80 degrees F (26.7 degrees C) and then at 100 degrees F (37.8 degrees C) unit the pH reached wither 5.2 or 4.7. The mix was then heated to 110, 115, or 120 degrees F (43.3, 46.1, or 48.9 degrees C). The bologna was sampled at various times, decimally diluted, and plated on either McConkey sorbitol agar or XLD agar to enumerate E. coli O157:H7 and S. typhimurium, respectively. Fermentation alone reduced populations of both pathogens by < 2 log units and heating alone reduced populations of E. coli O157:H7 by < 3 log units. A combination of fermenting to either pH 5.2 or 4.7, followed by heating at 110 degrees F (43.3 degrees C) for 20h, 115 degrees F (46.1 degrees C) for 10 h, or 120 degrees F (48.9 degrees C) for 3 h reduced populations of both pathogens by > 7 log units. Overall S. typhimurium cells were either equally or significantly less resistant (P < 0.01) than cells of E. coli O157:H7. Significantly interactions (P < 0.01) among the three factors for the destruction of E. coli O157:H7 were observed. A process-specific regression equation was developed to predict the destruction of E. coli O157:H7 in Lebanon bologna.

The health of family caregivers of older impaired persons in Lebanon: an interview survey.

BACKGROUND: The majority of older persons in Lebanon live with their family, which provides the help and care required when their relative is functionally impaired. Knowing that taking care of an older impaired relative is considered a source of enrichment for the caregiver and an act of gratitude towards the older person in Lebanon. However, there are few formal resources to support these families. This study is informed by a theoretical framework of stress. OBJECTIVE: Identify the dimensions of the caring context related to the health of Lebanese family caregivers living with an older impaired relative. DESIGN: Exploratory correlational study. PARTICIPANTS: Convenience sample (N=319) drawn from all the regions of Lebanon according to predetermined quotas on the basis of relative demographic weight and socio-economic class. The inclusion criteria are: aged 18 years or over; primary caregiver; provided help with at least one ADL or IADL once a week; lived with the older impaired person. 13.5% refused to participate in the study. The caregivers recruited were female (84%), adult children (48%) or spouses (22.6%) with a mean age of 46 years. Almost half of them reported a post-compulsory level of education and a low monthly household income and no medical coverage for 68% of them. METHODS: The data were collected during a face-to-face interviews with the caregivers in their homes. RESULTS: The results from regression analyses indicate that the degree of functional impairment, the frequency of depressive and disruptive behaviours of cared-for relative are linked to at least one of three caregiver health indicators (p<.01). Also, caregiver cognitive appraisal of these stressors is associated with either role strain or feeling of helplessness (p<.05). The informal emotional support received by caregivers is positively related to well-being (p<.001), whereas interpersonal conflicts with family and friends diminish caregiver well-being and increase role strain (p<.001). Sufficiency of emotional support received is negatively associated with role strain (p<.001). CONCLUSION: Many stressors proved associated with one or other of the health indicators under study and the resources emerged as significant factors related to caregiver's health.

Isolation, molecular characterization and antimicrobial resistance patterns of Salmonella and Escherichia coli isolates from meat-based fast food in Lebanon.

The aim of this study was to characterize at the molecular level the different stains of Salmonella spp. and Escherichia coli that were isolated from meat-based fast food in Lebanon. In addition, this study evaluated the resistance of those strains to different antimicrobials that are commonly used. The foods included were Lahm-bi-Ajeen (LBA, meat pies) and Shawarma (Lebanese meat sandwiches similar to Gyros and Donairs, containing meat, vegetables, and sesame seeds-oil-based sauce). Polymerase chain reaction (PCR) was used to characterize and identify the strains of both bacteria. Salmonella species characterization was performed using rfb genes cluster genetic marker, while that of E. coli strains were carried out based on stx1, stx2, eaeA, fliC, and ehlyA virulence markers. The characterized strains were then tested for their response to various antimicrobials. The results showed that the tested foods were contaminated with Salmonella paratyphi (serogroup A) and Shiga Toxin (Stx)-producing E. coli (STX-EC). The PCR showed that 75% of E. coli tested strains was positive in PCR performed with stx1 primers, one of which was eaeA positive. Two of the tested strains were positive using PCR with fliC primers. The resistances of the various strains were evaluated using the following antimicrobials: Oxacillin, Teicoplanin, Trimethoprim/sulfamethoxazole, Gentamicin, Clindamycin, Cefotaxime, Cefuroxime, Erythromycin, and Vancomycin. Bacteria were highly resistant to one or more of the tested antimicrobials. Approximately 69% of E. coli and 77.8% of Salmonella spp. exhibited resistance. Salmonella spp. were shown to be 100% resistant to four antimicrobials: Oxacillin, Teicoplanin, Clindamycin, Vancomycin, and Erythromycin, while E. coli was 100% resistant to Teicoplanin and Trimethoprim/sulfamethoxazole. The most interesting findings were the high susceptibility of the E. coli to Gentamicin (100%). Highest resistance in the case of Salmonella spp. was seen against Cefotaxime (74%). Those two antimicrobials are commonly used for the treatment of enteric infections caused by gram-negative bacteria. The results showed that meat-based fast foods in Lebanon could be a public health hazard, especially Shawarma, as they may act as a potential vehicle for many antimicrobial-resistant pathogenic organisms. Improper hygienic standards and indiscriminate use of antimicrobials are two of the main causes for the prevalence of these pathogenic resistance strains in Lebanon. These results will emphasize the need to implement protective measures and more emphasis will be placed on the application of hygienic practices to reduce the levels of food contamination.

Drug-related hospitalization at a tertiary teaching center in Lebanon: incidence, associations, and relation to self-medicating behavior.

OBJECTIVE: In Lebanon there is very limited restriction on drug use. Accordingly, self-medication is highly prevalent. This study examined the influence of these factors on the development of drug-related illnesses that lead to hospitalization. METHODS: Patients admitted to the medical and pediatric wards of a tertiary teaching center in Beirut, Lebanon, over a period of 6 months were interviewed and their charts were reviewed. Admissions attributable to adverse drug reactions or therapeutic failures were identified and characterized with respect to demographic factors, medical history, drug intake, and self-medicating behavior. The influence of these variables on the development of drug-related illnesses was examined by logistic regression. RESULTS: Of 1745 adults and 457 children, there were 177 (10.2%) and 36 (7.9%) drug-related illnesses, respectively. Adverse drug reactions accounted for 7.0% and 5.7% and therapeutic failures for 3.2% and 2.2% of adult and pediatric admissions, respectively. Self-medication was commonly practiced (52.6% of adults and 41.6% of children). Logistic regression analysis revealed that female sex increased the risk of adverse drug reaction in adults, whereas self-medication decreased the risk. In children, the risk of adverse drug reaction was increased in lower socioeconomic groups, whereas the risk of therapeutic failure was increased by a positive history of atopy or drug reaction. CONCLUSIONS: These results provide the first detailed analysis of the problem of drug-related illnesses in a developing country and identify a number of related or risk factors. Despite the lack of regulation of drug dispensing and the unchecked access to drugs in Lebanon, the incidence of drug-related illnesses is not different from that in Western nations. This finding may have relevance to policies of drug regulation in other countries.

Current prevalence of hepatitis delta virus (HDV) infection and the range of HDV genotypes in Lebanon.

Recently the prevalence of hepatitis B virus (HBV) genotypes and the association between these genotypes and the clinical status of HBV-infected patients were recently investigated in the Lebanese population. The aim of the additional study reported here was to determine the current prevalence of hepatitis delta virus (HDV) infection and the range of HDV genotypes in this Lebanese population. Two hundred and fifty-eight HBsAg-positive patients (107 asymptomatic blood donors, 92 with chronic hepatitis, 24 with cirrhosis, 15 with hepatocellular carcinoma, 20 patients on haemodialysis) from ten medical centers in Lebanon were tested for antibody to hepatitis D virus (anti-HDV). Those testing positive were analysed further for HDV-RNA and for genotyping by reverse transcriptase-polymerase chain reaction (RT-PCR) and restriction fragment length polymorphism (RFLP). Three samples (1.2%) were anti-HDV positive and out of these, only one was HDV-RNA positive (0.6%) and was analysed as HDV genotype I. Our results point to a low endemicity of HDV in the Lebanese population which is in sharp contrast to data reported from Lebanon 20 years ago and to the situation in neighbouring Arab and non-Arab countries in the Mediterranean region. HDV genotype I seems to be the predominant genotype in Lebanon and the Middle East.

Breast-feeding and feeding practices of infants in a developing country: a national survey in Lebanon.

OBJECTIVE: Breast-feeding (BF) provides the ideal food for the healthy growth and development of infants. The prevalence of BF in Lebanon shows mixed results. The present study was the first large-scale, extensive survey on BF parameters in Lebanon that aimed to explore demographic, socio-economic and other fundamental issues associated with the initiation and duration of BF by Lebanese mothers. DESIGN: The survey was cross-sectional in design and administered over 10 months. SETTING: Information on all variables was collected from mothers at health centres. SUBJECTS: Two-stage sampling was conducted to select participants. A total of 1,000 participants were randomly selected. A consent form was provided to each participant. Data were collected from 830 of these. RESULTS: Almost all mothers were Lebanese, married and had given birth in a hospital. About a third stated that breast milk was the first food introduced after birth. Although 55.9% started breast-feeding their newborns within a few hours after birth, and 18.3% within half an hour, 21.2% replied that they initiated BF a few days after birth. Only 4.6% of the mothers replied that they never breast-fed their infant. Timing of initiation of BF was associated with the type of delivery (vaginal/Caesarean section) and hospital-related factors (rooming-in, night feedings and frequency of mother-infant interaction). Of the mothers who breast-fed exclusively beyond 6 months, 86.7% had initiated BF a few hours following delivery, while only 13.3% had initiated BF a few days later. Compared with the exceptionally high proportion of BF initiation, exclusivity of BF was low, dropping to 52.4% at 1 month. Exclusivity of BF was also associated with place of residence (urban/rural) and negatively associated with educational level of the mother. Duration of BF was inversely associated with the use of pain killers during delivery and maternal education. Rural mothers and those who practised exclusive BF maintained BF for a longer duration. CONCLUSION: Initiation rates of BF are very high in Lebanon but rates of exclusive BF are low and duration of BF is short. Future research targeting the factors associated with BF, with particular emphasis on exclusivity, is needed. For the 95.4% of mothers who initiated BF, an ecological perspective on intervention aimed at women and their social support system is required to improve duration and exclusivity.

Age at natural menopause in Beirut, Lebanon: the role of reproductive and lifestyle factors.

PRIMARY OBJECTIVE: To determine the median age of natural menopause and factors associated with the timing of menopause in Beirut, Lebanon. RESEARCH DESGIN: A population-based sample of 298 women were interviewed using a semi-structured questionnaire. METHODS AND PROCEDURES: Logit analysis and logistic regression were used to estimate the median age and identify correlates of menopausal status. MAIN OUTCOMES AND RESULTS: The median age of natural menopause in Beirut, Lebanon is estimated to be 49.3 years. Not being currently married (odds ratio (OR)=4.19, 95% CI: 1.53, 11.51) and smoking (OR = 1.02 for each year of smoking, 95% CI: 1.00, 1.05) are significantly associated with an earlier age at menopause. Women with menstrual bleeding longer than 5 days have later ages at menopause (OR = 0.50, 95% CI: 0.26, 0.97). Age at menarche, parity, education and socio-economic status are not statistically associated with the age at menopause. CONCLUSIONS: The age at natural menopause in Lebanon is comparable to median ages reported for women in industrialized countries (49.3-51.4). Our results emphasize the role of smoking in determining an earlier age at menopause and indicate that reproductive characteristics affect the timing of menopause.

Reform follows failure: I. Unregulated private care in Lebanon.

This first of two papers on the health sector in Lebanon describes how unregulated development of private care quickly led to a crisis situation. Following the civil war the health care sector in Lebanon is characterized by (i) ambulatory care provided by private practitioners working as individual entrepreneurs, and, to a small extent, by NGO health centres; and (ii) by a fast increase in hi-tech private hospitals. The latter is fuelled by unregulated purchase of hospital care by the Ministry of Health and public insurance schemes. Health expenditure and financing patterns are described. The position of the public sector in this context is analyzed. In Lebanon unregulated private care has resulted in major inefficiencies, distortion of the health care system, the creation of a culture that is oriented to secondary care and technology, and a non-sustainable cost explosion. Between 1991 and 1995 this led to a financing and organizational crisis that is the background for growing pressure for reform.

Countrywide spread of community- and hospital-acquired extended-spectrum beta-lactamase (CTX-M-15)-producing Enterobacteriaceae in Lebanon.

A prospective study was carried out to assess the extent of carriage of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae at both hospital and community levels in Lebanon. A total of 1,442 fecal samples were collected from hospital-based patients and 58 from health care workers of six Lebanese tertiary care general hospitals located in different areas of Lebanon between January and March 2003. A total of 382 fecal samples were also collected from healthy subjects between April and June 2003. The samples analysis led to the identification of 118 strains as ESBL producers based on the synergistic effects between clavulanate and selected beta-lactams (ceftazidime and cefotaxime). These strains were isolated from 72 subjects: 61 patients, 2 health care workers, and 9 healthy subjects. One representative strain per subject was selected, and a total of 72 nonduplicate ESBL producers, including a high majority of Escherichia coli (n = 56), Klebsiella pneumoniae (n = 9), Enterobacter cloacae (n = 6), and Citrobacter freundii (n = 1), were characterized. The molecular analysis revealed that the majority of the strains (83%) express CTX-M-15 ESBL (pI 8.6). SHV-5a ESBL (pI 8.2) was produced by 18% of the strains. DNA macrorestriction analysis of ESBL-producing E. coli presented 38 different genotypes, revealing the absence of clonal link among these strains. In addition to the fact that the present study highlights the emergence and the countrywide dissemination of CTX-M-15-producing E. coli in Lebanon, it represents the first report of an SHV-5a-producing C. freundii.

Tracking the shifting landscape of SARS-CoV-2 variants in Lebanon among healthcare workers and hospitalized patients.

UNLABELLED: Genomic surveillance of SARS-CoV-2 is critical for tracking viral evolution and informing public health responses. This study characterized variants circulating among healthcare workers (HCWs) and hospitalized patients in Lebanon between January 2022 and September 2024. A total of 530 SARS-CoV-2-positive nasopharyngeal swabs were collected from five Lebanese governorates and subjected to whole-genome sequencing. Correlations between variant circulation and a number of demographic and clinical variables were assessed. Most HCWs were female (64%), young adults (20-30 years, 39%), and had no comorbidities (97%). In contrast, hospitalized patients were mostly older adults (>60 years, 55.6%) with underlying conditions (77%). Early 2022 was marked by BA.1- and BA.2-like Omicron variants, followed by the predominance of BA.5-like lineages. In 2023, recombinant XBB sublineages became widespread. By 2024, these were largely replaced by next-generation variants, including JN.1 and KP.3.1.1. Despite differences in demographics and exposure risk, both groups showed parallel variant evolution. These findings reflect global and regional patterns and highlight the dynamic nature of SARS-CoV-2 circulation in Lebanon. IMPORTANCE: This study provides a comprehensive snapshot of SARS-CoV-2 variant evolution in Lebanon between 2022 and 2024, focusing on healthcare workers and hospitalized patients. By combining genomic and clinical data, it reveals how successive Omicron subvariants emerged and spread within key population groups. The detection of diverse and evolving lineages, including XBB recombinants and next-generation variants such as JN.1, underscores the ongoing antigenic drift of SARS-CoV-2. These insights reinforce the value of continued genomic surveillance for pandemic preparedness, especially in regions where data remain limited. Understanding local variant dynamics can guide targeted vaccination strategies and health policy decisions.

Molecular characterization of pESI-like megaplasmids in Salmonella Infantis from poultry in Lebanon.

UNLABELLED: Salmonella enterica serovar Infantis has emerged as a globally disseminated multidrug-resistant (MDR) pathogen, largely driven by the spread of the plasmid of emerging Salmonella Infantis (pESI)-like megaplasmid. In our study, we investigated the prevalence, antimicrobial resistance (AMR) phenotypes, and genomic features of S. Infantis isolates collected from poultry farms in Lebanon. A total of 72 isolates were recovered during a nationwide surveillance effort, among which 67 (93%) were MDR based on antimicrobial susceptibility testing (disk diffusion and broth microdilution) results, including resistance to critically important agents such as quinolones, and highly important classes such as tetracyclines and sulfonamides. Whole-genome sequencing was performed on 19 isolates selected through a stratified approach to encompass all identified AMR phenotypes; this analysis revealed a conserved pESI-like backbone together with MDR-associated determinants, including sul1, tet(A), and aadA. Plasmid marker analysis confirmed the presence of pESI in the majority of isolates, with plasmid-associated genes (ardA and trbA) and replicon markers (IncP and IncFIB(pN55391)) among the most prevalent. Comparative plasmid alignments with representative pESI sequences from Italy, Turkey, and the United States revealed strong conservation of the backbone alongside regional variation in AMR gene content. These findings highlight the role of poultry production systems in Lebanon as reservoirs for pESI-like megaplasmids and MDR S. Infantis, underscoring the zoonotic and public health risks posed at the human-animal-environment interface. Strengthened surveillance, antimicrobial stewardship, and biosecurity interventions are urgently needed to mitigate the spread of MDR S. Infantis within agriculture and beyond. IMPORTANCE: The emergence of plasmid of emerging Salmonella Infantis (pESI)-like megaplasmids has transformed Salmonella Infantis into a globally distributed multidrug-resistant (MDR) clone with the capacity to persist in livestock and disseminate resistance genes across ecological boundaries. Our study provides the first genomic characterization of pESI-positive S. Infantis from poultry farms in Lebanon, a region with high antimicrobial usage and limited stewardship frameworks. By integrating phenotypic susceptibility testing and whole-genome sequencing, we demonstrate that Lebanese isolates harbor conserved pESI-like backbone markers together with antimicrobial resistance determinants, aligning them with internationally circulating lineages. Comparative analysis with isolates from Italy, Turkey, and the United States highlights both the evolutionary stability and geographic diversity of pESI. These findings emphasize the urgent need for integrated surveillance and stewardship strategies to curb the spread of MDR S. Infantis and reduce the zoonotic risk at the human-animal-environment interface.

Psychosocial and economic profile of a sample of families with thalassaemic children in Lebanon.

Thalassaemia major is a relatively common disease in Lebanon. This study of 41 families with 54 patients attending the American University of Beirut Medical Center was conducted to define some aspects of the disease in Lebanon and to assess the attitudes of affected families on relevant psychosocial and economic issues. We conclude that because of the high frequency of consanguineous marriage, thalassaemia major is more common in Lebanon than might be expected on the basis of the incidence of the trait. Most patients are diagnosed early in life, but their treatment is generally far from adequate; securing desferrioxamine and paying for follow up visits to the doctor seem to be the most important financial burdens. The general population of the country is not properly informed yet and about 70% of the families had not heard about the disease before having an affected child. The inherited nature of the disease is not clear in the minds of a high percentage of the families, and in about 30% of cases the family had not been told about the advisability of screening to detect heterozygotes. The great majority of families favour a preventive approach to thalassaemia, based on heterozygote screening and the possibility of prenatal diagnosis.
