Flu, according to the DOH is transmitted when the influenza virus enters into the respiratory tract when someone coughs or sneezes. It is also transmitted via ontact with the surfaces, material, and clothing contaminated with discharges of an infected person.

Signs and symptoms

The signs and symptoms of flu include fever of at least 38°C, runny nose, sore throat, cough, or other respiratory manifestations, and sometimes muscle of joint pains.


Flu is prevented by minimizing contact with a person who has influenza, avoiding crowded places, and getting vaccinated against the viral infection yearly. Washing hands frequently with soap and water and covering the mouth and nose when sneezing or coughing also helps prevent the spread of the virus.


The use of antiviral agents, such as oseltamivir or zanamivir, within the first 2 days may shorten the illness and help prevent serious complications, the DOH says. Also important are having adequate rest and increasing the intake of fluids and nutritious food. For fever, paracetamol may be taken.
