Caused by the Influenza virus, the flu is found throughout the year in Thailand but spreads quickest during the rainy season. The flu can affect anyone of any age. However, children are more at risk than adults, especially young infants.
The virus is spread via contact with saliva and nasal secretion of someone already infected.
Symptoms of the flu
The symptoms may worsen to a point where admission to hospital is required due to complications, such as pneumonia, resulting from the virus.
Virus screening is carried out with a swab test taken from the throat or nose of the patient, with results being at their most accurate once the patient has already experienced a fever for 24 hours.
