AIDS (Acquired Immune Deficiency Syndrome) was first recognized in 1981 and originated from Africa. It has led to the deaths of more than 2.1 million people, including 330,000 children. 77% of women in sub-Saharan Africa are living with AIDS. AIDS is an infectious disease that attacks the human immune system. It is caused by a retrovirus and spread by transfer of infected blood, a contaminated hypodermic needles or by being born to a mom who is infected. Malaria is one of the most common infectious diseases caused by a protozoan transmitted by infected anopheles female mosquitoes, and resulting in intermittent chills and fever or any foul of unwholesome air. It results in about one to two million deaths annually; most of which are young children. Malaria originated from Africa and eventually spread through in other places in Asia and some parts of America. Typhus is one of the oldest pestilential diseases of mankind caused by louse-borne bacteria. It is an acute, specific infection caused by Rickettsia prowazeki. It’s consists of groups of contagious rickettsial diseases marked by high fever, a rash, a nervous and mental disorders and extreme prostration. Most of Napoleon’s soldiers in Russia were killed by Typhus between 1919 and 1923; 3 million people have killed. Cholera is an acute, infectious gastroenteritis caused by enterotoxin-producing strains of the bacterium Vibrio cholera, epidemic disease, characterized by serious intestinal disorders. Eight types of cholera pandemics have killed millions of people worldwide as it first originated in the Ganges River delta in India. Smallpox is a contagious, epidemics deadly disease throughout history caused by the variola virus that emerged in human populations and eradicated from nature. This contagious disease killed 3 million people yearly in the 20th century. Smallpox was started in East Asia and spread through India, Africa and the Middle East. Spanish Flu is an influenza pandemic that killed between 30 to 100 million people with unusually high death rates among healthy adults and young in less than 2 years as it rapidly spread around the world. It was the worst infectious pandemic in history and originated in France in 1916. Now the seventh killer plague would be Swine Flu.... Hope so we will be able to get medicine for these diseases.
