By Angelica. N. Kuria

Background ILI sentinel surveillance system Case definition Data analysis Results Conclusion Implications

Laboratory confirmation of the cause of ILI is very important as it will dictate the management instituted

Influenza, RSV, and certain bacterial infections can lead to serious complications requiring hospitalization

ILI can spread rapidly and outbreaks can have potentially devastating consequences, particularly for immunocompromised persons hence need for sentinel surveillance

More males were affected (56.3%)

All the four regions in Tranquilidad were affected by the respiratory viruses

Influenza A was the major cause of ILI while RSV was the least cause

• Most cases occurred between weeks 29 and 36

• Residents should be vaccinated against the respiratory viruses early enough to prevent outbreaks as most cases occur between weeks 29 and 36

• More surveillance in the region is needed to determine why some viruses are more prevalent in one region than the other
