How are viruses transmitted?
There are multiple ways viruses can be transmitted, including:
1. Contact Transmission: This includes direct contact with an infected person or animal through touching, kissing, or sharing bodily fluids, as well as indirect contact with surfaces or objects contaminated with the virus.
2. Respiratory Transmission: Viruses can be transmitted through droplets or aerosols containing infectious particles that are released into the air when an infected person coughs, sneezes, talks, or breathes heavily. These droplets or aerosols can then be inhaled by others.
3. Fecal-Oral Transmission: This occurs when someone ingests food or water contaminated with feces containing the virus.
4. Blood or Body Fluid Transmission: This involves contact with infected blood, semen, or vaginal fluids during unprotected sexual intercourse, blood transfusions, needle sharing, or occupational exposures.
5. Zoonotic Transmission: Viruses can be transmitted from animals to humans, either through direct contact or by intermediary vectors like mosquitoes, ticks, or fleas.
6. Vector-Borne Transmission: Some viruses are transmitted by insects, such as mosquitoes, ticks, or sandflies. These insects carry the virus and transmit it to humans through their bites.
