This article summarizes the important characteristics of these occurrence and the practical strategy of infection preventionism in education and protection of medical workers.

Norovirus is a very infectious virus that causes acute gastroenteritis. The CDC shows 91 outbreaks in the United States until December 5, 2024.^1* It spreads mainly through direct contact with contaminated foods, water, surface, and infected people. Symptoms, including diarrhea, vomiting, and stomach pain, usually appear within 12 to 48 hours of exposure and can last up to three days. Norovirus can survive on the surface for several weeks, making environmental hygiene a top priority for facilities.

Bird flu, especially H5N1 stocks, mainly affect birds, but rarely intersects humans by directly contacting infected poultry or contaminated environment. H5N1 human cases can cause severe respiratory diseases with symptoms such as fever, cough, and dyspnea. Propagation from humans to humans is very rare, but the mortality rate remains high. CDC confirmed several cases of bird flu in the United States in December 2024.²

Infection prevention doctors need to guarantee that medical professionals understand the path and clinical symptoms of norovirus and bird flu.

Bird flu, such as N95's respiratory organs, eye protection, and negative rooms, requires air and contact prevention measures.⁴

There is no norovirus vaccine, but seasonal influenza vaccination may provide partial protection against bird flu. Depending on the risk of infection, infectious diseases must be able to access appropriate personal protection equipment, such as gloves, gowns, masks, and face shields. A clear and consistent communication is essential. Staff must regularly update outbreak status, protocol change, and available resources. E -mail, posters, and face -to -face briefings are used in daily safety flocks to efficiently spread information.

The occurrence of norovirus and bird flu requires efforts to be alerted by infection preventionists to protect medical workers and patients. In particular, at the time of entry of facilities (such as emergency treatment rooms), continuous reminders of hygiene practices, and effective communication, medical facilities relieve the effects of these infections and maintain a safe environment during the winter. You can. season.
