[Respiratory virus in children aged less than 10 years old suffering from respiratory infection in the Hospital Militar Central in Bogota from 2000-2001].

Objective: A study was carried out on children seeking medical care at the Hospital Militar (Hosmil) in Bogota due to acute respiratory infection; it was aimed at estimating the frequency of respiratory virus-associated acute respiratory disease (ARD) in children aged under 10.

Methods: Three to five children aged less than 10 years old were selected every week from the hospital's emergency ward or ambulatory services over an 18-month period from March 2000 to September 2001. Nasopharyngeal samples were obtained from them and processed using indirect immunofluorescence.

[Adenovirus in children under five years of age. Circulation patterns and clinical and epidemiological characteristics in Colombia, 1997-2003].

Objective: The Colombian National Institute of Health has been studying the epidemiology of several respiratory viruses since 1997 to identify their circulation patterns and the role they play as pathogenic agents of acute and/or moderate respiratory infection (RI) in children aged less than 5.

Methods: The study used sentinel surveillance methods in sentinel hospitals in Bogotá and Manizales. Four to eight nasopharyngeal samples were collected every week in the sentinel hospitals from children aged less than five consulting for low or high RI.
