“…Among them, four evaluated vaccine coverage among health professionals and/or immune-deficient patients (Table 1). Among health professionals, two surveys conducted in two of the leading university hospitals in the country presented coverage of 19.7% and 34.4% 4,33 . In the same institutions, vaccine coverage among transplant patients varied between 44.2% (bone marrow transplant) and 0% (kidney) 5,25 .…”

SUMMARYSince 1999, Brazil has undertaken annual influenza vaccine campaigns, free of charge, targeting the elderly population, health professionals, and immune-deficient patients. We conducted a systematic review of literature in order to evaluate the effectiveness of the initiative. We used the keywords influenza, vaccine, Brazil and effectiveness to search the main databases. Thirty-one studies matched our inclusion and exclusion criteria. Influenza vaccine coverage among the elderly is high, though not as high as suggested by the official figures. Estimates on effectiveness are scarce. The majority come from ecological studies that show a modest reduction in mortality and hospital admissions due to influenza-related causes. Such reduction is not evident in the North and Northeastern states of Brazil, a finding that is probably related to the different seasonal pattern of influenza in equatorial and tropical regions. Brazilian epidemiologists still owe society better-designed studies addressing the effectiveness of influenza vaccine campaigns.

“…In another study performed in Salvador by NASCIMENTO-CARVALHO et al HRV was the most common viral pathogen (21%), detected in the same proportion as Streptococcus pneumonia 36 . BELLEI et al evaluated the frequency of viral infections among healthcare workers in São Paulo and showed a predominance of HRV (37.7%) 6 . BONFIM et al studies on the frequency of respiratory pathogens in children attending daycare centers in São José do Rio Preto, São Paulo, between 2003 and 2005, also showed the predominance of HRV (37.7%) 8 .…”

SUMMARYThe frequency of viral pathogens causing respiratory infections in children in the cities of Rio de Janeiro and Teresópolis was investigated. Nasal swabs from children with acute respiratory illnesses were collected between March 2006 and October 2007. Specimens were tested for viral detection by conventional (RT)-PCR and/or real time PCR. Of the 205 nasal swabs tested, 64 (31.2%) were positive for at least one of the viral pathogens. Single infections were detected in 56 samples, 50 of those were caused by RNA viruses: 33 samples tested positive for rhinovirus, five for influenza A, five for metapneumovirus, four for coronavirus and, three for respiratory syncytial virus. For the DNA viruses, five samples were positive for bocavirus and one for adenovirus. Co-infections with these viruses were detected in eight samples. Our data demonstrate a high frequency of viral respiratory infections, emphasizing the need for a more accurate diagnosis particularly for the emerging respiratory viruses. The fact that the emerging respiratory viruses were present in 9.2% of the tested samples suggests that these viruses could be important respiratory pathogens in the country.
