Legionnaires’ disease acquired its name in July 1976, when an outbreak of pneumonia occurred among people attending a convention of the American Legion in Philadelphia. It’s a form of atypical pneumonia with symptoms that include cough, shortness of breath, high fever, muscle pains, and headaches. This often begins two to ten days after being exposed.
Cholera is an infection of the small intestine and affects an estimated 3–5 million people worldwide, causing 28,800–130,000 deaths a year.. t is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria and undercooked seafood is a common source. Though the classic symptom is large amounts of watery diarrhea that lasts a few days causing dehydration and electrolyte imbalance, vomiting and muscle cramps may also occur. Prevention methods against cholera include improved sanitation and access to clean water. Cholera vaccines that are given by mouth provide reasonable protection for about six months.
