1. Ebola virus: This filovirus causes Ebola virus disease (EVD), which can lead to severe hemorrhagic fever and high mortality rates. It is transmitted through contact with infected bodily fluids or contaminated surfaces.
2. Human Immunodeficiency Virus (HIV): HIV targets the immune system and weakens people's defense systems against infections and some types of cancer. This virus causes acquired immunodeficiency syndrome (AIDS) if not treated properly.
3. Rabies virus: Rabies is a fatal zoonotic viral disease that affects the central nervous system. It is primarily transmitted through the bite of infected animals, such as dogs and bats.
4. Measles virus: Measles is a highly contagious respiratory viral disease that can lead to complications like encephalitis, pneumonia, and blindness. It is transmitted through respiratory droplets and is highly preventable with vaccination.
5. Influenza virus: Influenza viruses cause seasonal flu, which can range from mild to severe. Some influenza virus strains, such as the highly pathogenic avian influenza A (H5N1), can lead to severe respiratory illness in humans.
6. Poliovirus: Poliovirus causes poliomyelitis, a highly infectious disease that can lead to paralysis and permanent disability. It is transmitted through contact with the fecal matter of infected people or contaminated food and water.
7. Hepatitis B virus (HBV): Hepatitis B virus can cause chronic liver disease, cirrhosis, and liver cancer. It is transmitted through contact with infected bodily fluids, such as blood or semen.
8. Hepatitis C virus (HCV): Hepatitis C virus also leads to chronic liver disease, cirrhosis, and liver cancer. It is primarily transmitted through contact with infected blood.
9. Dengue virus: Dengue virus is a mosquito-borne virus that causes dengue fever, a tropical disease that can lead to severe flu-like symptoms and, in some cases, develop into life-threatening dengue hemorrhagic fever and dengue shock syndrome.
10. Yellow fever virus: Another mosquito-borne virus, yellow fever causes a viral hemorrhagic fever with symptoms like fever, jaundice, bleeding, and organ failure.
