Viral fevers are difficult to prevent. They occur as epidemics of infection depending on their mode of spread. Vaccines have been tried targeting the respiratory and gastrointestinal viruses with little success due to several sub-groups of viruses with different forms of antigenicity, all of which cannot be covered with a single vaccine. Fortunately since most infections are mild and self-limited, we can be assured of a full recovery.
