9. HIV and AIDS – The World’s Worst STD
The Human Immunodeficiency Virus is the infection that results in Acquired Immune Deficiency Syndrome. This STD has no known cure and is therefore one of the most dangerous diseases on the planet. It attacks the body’s immune system directly, therefore leaving it unprotected. You are then susceptible to all other infections and diseases. The US Center for Disease Control reveals that roughly three in one-thousand Americans will contract HIV. The symptoms vary, including indications that resemble flu. High fevers, chronic diarrhea and unexplained weight loss are also common. Coughing, shortness of breath and swollen lymph nodes are also common. HIV and AIDS are one of the most serious health conditions ever to plague mankind. Infection rates skyrocket in third-world countries.
