The Health Ministry has called on citizens to be wary of influenza during the rainy season, even though there has not yet been a serious outbreak.
The communicable disease control department has posted a short video clip to explain how to treat and prevent influenza so that everyone can protect themselves and their family.
The department said countries in the region had reported outbreaks in the rainy season, when the disease spreads.
Research has found that the strains H1N1, H3N2, influenza B and C often appear in Cambodia.
Ly Sovann, Health Ministry spokesman and director of the communicable disease control department, said yesterday there were a few cases of influenza last month but these did not cause serious problems.
Symptoms of influenza are temperature increases of more than 38.5 Celsius, a cough, sore throat and fatigue.
Last month, Mr Sovann warned people to be aware of the new avian influenza strain H7N9, which has spread to poultry in China and neighbouring countries.
