[Antibodies against hepatitis C virus. Study in voluntary blood donors. Cuba 1991].

Four hundred and sixty one samples randomly selected among blood donors from three blood banks in Havana City were investigated for HCV antibodies. Samples repeatedly reactive to Organcon Tecknica immunoenzymatic assay were considered positives and were further confirmed by an Ortho test. An epidemiological survey was conducted among all donors included in the sample to assess infection risk factors. Seven subjects (1.5%) resulted repeatedly reactive to the test, slightly higher than in developed countries. Mean age in positive patients was seven years higher than in negative subjects (39 vs 31.5), but the Student's test did not show any significant difference. Seropositivity was higher in males (1.7 vs 0.9) and very similar as to the color of skin (1.9 mulattos, 1.5 whites and 1.0 blacks) but it was not statistically significant (p > 0.05). Among risk factors with higher odd ratios were to have more than five sexual partners in the last five years and having worked in a health care institution, but this was not statistically significant (p > 0.05). The probability of receiving one unit of HCV infected blood was of 1.5% and 45% when receiving 40 units. Given the importance of the virus, the need of establishing specific control measures in the shortest period of time for HCV detection in blood is under-lined.

[Histoplasmin reactivity in poultry farm workers in the province of Ciego de Avila, Cuba].

An epidemiological survey with histoplasmin skin test was performed in 392 poultry farmers and 265 workers considered without occupational risk of exposition to Histoplasma capsulatum, etiologic agent of histoplasmosis. The results were positive in 28.8% and 13.2% in both groups respectively. Statistically, there was a significant difference between the two groups, so it can be considered that poultry farmers are in occupational risk of infection with H. capsulatum. In the first group, the workers which are more closely related with chicken manure showed a higher reactivity to histoplasmin skin test. The working time in the farms seems to influence in the test reactivity too.

[The estimation of the economic damages caused as a consequence of the epidemic of hemorrhagic dengue in Cuba in 1981].

In order to warn the health authorities in our region about the economic damages that a hemorrhagic dengue epidemic may cause, it was decided to study and publish the estimated cost of the Cuban epidemic in 1981, during which 344,203 diseased were reported, 10312 severe cases and 158 deceased. Economic costs include hospitalization expenses, assistance in emergency units, social security, expenses in out-patient treatment, goods not produced and expenses in the anti-vector campaign. Probably, this epidemic which could be controlled in about 4 months, has been the one causing most economic damages to date.
