Comparing Influenza and Cholera

The diarrhoea and vomiting, in turn, can cause very bad dehydration, leading to death if untreated. Flu symptoms include cough, sore throat, muscle aches and pains, fever, headache, and rarely vomiting and diarrhoea. Influenza can also lead to other diseases, such as pneumonia. This makes it especially dangerous to young children and old people. In other words, there is a big difference, apart from the rare case of D and V that can occur with flu.

It is most commonly spread by the microscopic droplets of mucus and fluid that are sent into the air when the sick person coughs or sneezes. Cholera is contracted by eating foods or drinking water contaminated with the bacterium Vibrio Cholerae. Sometimes, people get cholera...
