ABSTRACT

A survey of nasopharyngeal carriage of penicillin nonsusceptible pneumococcal (PNSp) isolates was conducted among 1192 children attending 62 day care centers in Brazil, where pneumococcal vaccination has not been routinely introduced. Nasopharyngeal pneumococcal carriage was detected in 686 (57.6%) infants, and 178 (25.9%) of them carried PNSp isolates. Being less than 24 months of age, hospitalization in the previous 3 months, and recurrent acute otitis media were independently associated with PNSp. Serotypes 14, 23F, 19A, 6A, 6B and 19F were the most common serotype isolated accounting for 80% of the PNSp. A high proportion (35/332) of non-(sero)typeable isolates was detected, 62.9% of them PNSp. Serotypes coverage projected for the pneumococcal conjugate vaccine (PCV) 13-valent vaccine (72%) was significantly higher compared with PCV7 (58.4%) and PCV 10-valent vaccine (59.3%).

ABSTRACT

Leprosy, a disease that used to be shrouded in darkness and fear, can now be cured thanks to a multidrug treatment schedule with rifampicin, clofazimine, and dapsone which has been in use since 1981. In 1991 the World Health Assembly, encouraged by the efficacy of this treatment regimen, established the goal of eliminating the disease as a public health problem globally and nationally by the year 2000. This goal, which calls for reducing disease prevalence to less than one case per 10 000 inhabitants, should not be confused with the goal of eradicating the disease, which implies a complete interruption of its transmission. Eliminating leprosy is an attainable goal which will depend on the forceful and massive use of the multidrug treatment regimen. This paper describes and discusses the various initiatives that have been launched in Latin America for the purpose of achieving this goal and the results obtained so far. It also explores the factors that impact on the feasibility of eradicating the disease (AU) (AU)
