Respiratory Viruses

Respiratory viruses can cause the common cold and influenza-like illness.

While you may be familiar with these illnesses – and have likely had them before – you may not be as familiar with all the different viruses that cause them.

For weekly case count updates for all respiratory viruses in Wisconsin, see the Weekly Respiratory Surveillance Report, P-02346.



People at higher risk

Though most people will only experience mild to moderate symptoms from a respiratory virus, some people may get seriously ill or even die. Those with weakened immune systems, infants, older adults, and those with existing lung or heart conditions are at a higher risk of developing severe illness. See our People at Higher Risk webpage for more information on what it means to be part of these groups.
