Here’s a summary table based on the concept of Virus: 101 Incredible Microbes from Coronavirus to Zika:

Virus	Key Information	Impact on Health	Transmission	Notable Facts
Coronavirus	A large family of viruses, including SARS-CoV-2 (COVID-19), that cause respiratory illness.	Can lead to severe respiratory issues, pneumonia, and death.	Primarily respiratory (airborne droplets, aerosols).	First identified in 1965, with the current pandemic originating in 2019.
Zika Virus	A mosquito-borne virus that causes mild illness but can lead to severe birth defects (e.g., microcephaly) when contracted during pregnancy.	Often mild symptoms, but dangerous for pregnant women.	Spread by Aedes mosquitoes (mosquito bites).	Outbreaks occurred in the Pacific Islands, Southeast Asia, and the Americas.
Influenza	A seasonal respiratory virus that causes flu-like symptoms, including fever, cough, and body aches.	Can cause severe respiratory infections and complications, especially in high-risk groups.	Person-to-person, through coughing or sneezing.	Annual vaccinations are recommended to prevent infection.
HIV (Human Immunodeficiency Virus)	A virus that attacks the immune system, leading to AIDS if untreated.	Weakens the immune system, increasing susceptibility to infections and cancers.	Blood, semen, vaginal fluids, and mother-to-child.	First identified in the early 1980s; treatments now allow for manageable viral load.
Hepatitis B	A virus that affects the liver, potentially leading to chronic disease, cirrhosis, or liver cancer.	Liver inflammation, possible long-term liver damage.	Blood and bodily fluids (including sexual contact).	Vaccination available for prevention.
Measles	A highly contagious viral infection characterized by a red, blotchy rash, cough, and fever.	Can lead to serious complications like pneumonia, encephalitis, or death.	Airborne transmission via coughing and sneezing.	A highly effective vaccine exists, but outbreaks still occur due to vaccine hesitancy.
Smallpox	A virus eradicated in the late 20th century, once causing deadly outbreaks marked by fever and distinctive skin rashes.	High mortality rate, severe scarring.	Airborne droplets, direct contact with infected fluids.	Eradicated in 1980, one of the greatest successes in public health.
Ebola	A viral hemorrhagic fever that causes severe bleeding, organ failure, and death in many cases.	High mortality rate, particularly in outbreak settings.	Direct contact with bodily fluids.	Outbreaks primarily in Central and West Africa.

This table covers a range of viruses with varying impacts, transmission modes, and unique characteristics, emphasizing their significance in public health and history.
