U00-U49: Provisional assignment of new diseases of uncertain etiology or emergency use

U11: Need for immunization against COVID-19

The need for immunization against COVID-19 falls under a group of conditions related to preventive health measures. COVID-19 is a viral illness caused by the SARS-CoV-2 virus, which spreads primarily through droplets from coughs or sneezes, as well as close contact with infected individuals. Common symptoms include fever, cough, difficulty breathing, loss of taste or smell, fatigue, and body aches. The disease can progress rapidly, mainly in vulnerable groups such as the elderly or those with underlying health conditions, and can affect various body systems, particularly the respiratory system. It's important to note that some individuals may show no symptoms but can still spread the virus. Immunization involves vaccination, which triggers an immune response that helps protect the individual from a future natural infection.
