10. Influenza

The CDC explains that “Influenza, (aka the flu), is a contagious and viral respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year. Every year in the United States, on average 5% to 20% of the population gets the flu; more than 200,000 people are hospitalized from flu complications, and; about 36,000 people die from flu-related causes. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.”

Unfortunately, the flu can mutate into new diseases such as bird flu and swine flu. According to the WHO, “Influenza affects mainly the nose, throat, bronchi and, occasionally, lungs. Infection usually lasts for about a week, and is characterized by sudden onset of high fever, aching muscles, headache and severe malaise, non-productive cough, sore throat and rhinitis.”

11. Avian Influenza (Bird Flu)

The CDC: “Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them. Infected birds shed influenza virus in their saliva, nasal secretions, and feces.

“Human influenza virus” usually refers to those subtypes that spread widely among humans. Symptoms of avian influenza in humans have ranged from typical human influenza-like symptoms to eye infections, pneumonia, severe respiratory diseases and other severe and life-threatening complications. “ The WHO estimates 421 cases and 257 deaths have occurred since the outbreak started in 2003. Indonesia was the country hardest hit by the disease with 115 deaths.
