respiratory virus infections

Respiratory virus infections are illnesses caused by viruses that primarily affect the respiratory system, including the nose, throat, and lungs. Common examples include the flu, common cold, and COVID-19. These viruses spread through respiratory droplets when an infected person coughs, sneezes, or talks. Symptoms often include cough, sore throat, fever, and fatigue. While many infections are mild and self-limiting, some can lead to more serious complications, especially in vulnerable populations. Good hygiene practices, such as handwashing and vaccination, can help prevent the spread of these viruses.
