RESUMO
Dengue disease statistics is mainly based on consulting patients with febrile illness, but misdiagnosed and asymptomatic cases are important to measure dengue epidemiology in endemic areas. The main objective of this work was to determine the prevalence of IgM and IgG antibodies or NS1 antigen and viral RNA in a group of healthy volunteers from an isolated village in Colombian Chocó rain forest. It found 51.7% of virologically PCR confirmed asymptomatic cases, despite low IgM seroprevalence. It was confirmed that all four serotypes are in the circulation and in 17.2% of individuals it detected natural coinfections of two or three different serotypes simultaneously. This is the first report in Colombia evaluating viremia in asymptomatic volunteers. These findings pose a big concern about the transmission of dengue virus by asymptomatic individuals because they can spread the virus without take appropriate control measures.
RESUMO
Since the initial description as an independent entity in 1989, there are various patients reported in the literature as suffering acute eosinophilic pneumonia. Despite its recognition as etiology of acute respiratory insufficiency, at present still remains weak the ability for diagnosis and treatment, in the opportune moment. The clinical features of a patient that followed algorthms of diagnosis, for acute repiratory insufficiency, are presented. The treatment employed is describe in the article.
