Risk of hepatitis A virus infection among sewage workers in Israel.

Sewage workers are exposed to a wide range of chemicals and biological agents, including the hepatitis A virus. Inasmuch as Israel is an endemic area for hepatitis A, it is unclear if sewage workers are at increased risk for hepatitis A or which factors contribute to such risk. The authors compared seropositivity of hepatitis A in 100 sewage workers with that in 100 blue-collar worker controls. Hepatitis A seropositivity was highly prevalent, but nonsignificant, in both sewage workers and controls (82% and 91%, respectively). In sewage workers, the major risk for serological positivity was age (odds ratio = 4.5, 95% confidence interval = 1.6, 12.4 for every 10 y). The factors associated negatively with seropositivity were years of education and years of seniority. The authors concluded that exposure to sewage is not a risk factor for hepatitis A infection in Israel, and, therefore, sewage workers do not require special attention in this regard.

Pertussis infection in fully vaccinated children in day-care centers, Israel.

We tested 46 fully vaccinated children in two day-care centers in Israel who were exposed to a fatal case of pertussis infection. Only two of five children who tested positive for Bordetella pertussis met the World Health Organization's case definition for pertussis. Vaccinated children may be asymptomatic reservoirs for infection.
