To determine the frequency of viral pathogens causing upper respiratory tract infections in non-hospitalized, symptomatic adults in the city of Rio de Janeiro. Viruses were detected in Co-infections were detected in 4. However, positive samples were detected all year round. Only Results presented in this report suggest that respiratory viral infections are largely under diagnosed in immunocompetent adults.
Although the majority of young adult infections are not life-threatening they may impose a significant burden, especially in developing countries since these individuals represent a large fraction of the working force.
Acute respiratory infections represent a significant morbidity and mortality burden worldwide and are caused primarily by viral infections. Since , the World Health Organization has advocated the surveillance of acute viral respiratory disease programs worldwide. Most data available focuses on specific populations such as immunosuppressed, 5 , 6 , 7 , 8 , 9 homeless, 10 , 11 or elderly individuals. Viruses are the leading causes of acute respiratory disease throughout the world.
In , the Brazilian Ministry of Health established a countrywide surveillance system for respiratory viral infections. This system comprises a network of sentinel units that include outpatient clinics, emergency care departments, and general hospitals that issue a weekly report using an online system informing the total number of visits and the number of visits associated with influenza-like illness ILI defined as a case of fever accompanied by cough or sore throat with no other diagnosis.
The aim of this study was to determine the frequency and type of upper respiratory viral infections in non-hospitalized adults in the city of Rio de Janeiro, Brazil over a period of two years using molecular diagnostic methods. Relevant clinical information including age, sex, and clinical symptoms were collected during the medical visit using a standardized questionnaire. The amplification conditions consisted of 10 min at 95 Β°C, followed by 45 cycles of 10 s at 95 Β°C and 60 s at 60 Β°C.
