How is Norovirus Spread?

The routes of transmission of norovirus generally include direct contact transmission, airborne transmission, and transmission through the digestive tract. Therefore, it is important to strengthen prevention in daily life.

1. Direct Contact Transmission: Norovirus can be transmitted through direct contact, such as by touching the feces and vomit of infected individuals, which contain the virus. Failure to promptly perform personal hygiene after contacting these substances may lead to contamination of the hands and induce infection. When handling the vomit and feces of patients, gloves should be worn to avoid direct contact with norovirus.

2. Airborne Transmission: When the excretions and vomit of infected individuals accidentally splash into the air, they may form small particles that can be inhaled through the respiratory tract and transmitted to healthy individuals. Masks should be worn when in contact with patients in daily life.

3. Digestive Tract Transmission: If food and water sources consumed in daily life are contaminated with norovirus, ingestion of such food will also lead to transmission through the digestive tract. Therefore, attention should be paid to dietary hygiene, and it is advisable to avoid consuming unclean food or raw meat.
