J09-J18: Influenza and pneumonia
J12: Viral pneumonia, not elsewhere classified
Viral pneumonia is a type of lung infection caused by various viruses, not classified under other specific types. These viruses can be easily transmitted from person to person through respiratory droplets when an infected person coughs or sneezes, or by touching surfaces contaminated by the virus and then touching the face. Common symptoms include a cough, high fever, and difficulty breathing, although they may vary depending on the severity of the infection and the virus involved. The disease progression can also differ, with some individuals recovering within a week, while others may take longer and experience more severe symptoms. This illness primarily affects the respiratory system, particularly the lungs, where it causes inflammation and sometimes fluid build-up that can impact breathing. It’s important to know that viral pneumonia can affect people of all ages but is more prevalent in those with a weakened immune system, the elderly, and children.
