To prevent a fever, you need to prevent the underlying illness or disease. How this is done depends on how the underlying illness or disease is transmitted.

In general terms, however, good personal hygiene is an important means of preventing any infection. Encourage your family members to wash their hands thoroughly and often, particularly before eating and after using the bathroom. Avoiding close contact with someone who is ill and not sharing food, drinks, or eating utensils can help halt the spread of germs as well.

In addition, vaccination is the best prevention for a wide range of diseases. Ensure that you and your children are properly vaccinated.
