Cholera is a deadly disease, caused by the bacterium Vibrio cholerae, which causes severe watery diarrhea. The World Health Organization states that signs of cholera can appear anywhere from 12 hours to five days after drinking contaminated water or eating contaminated food. Without treatment, this illness can cause death within hours. However, if caught early, it is easily treatable. The primary treatment for cholera involves rehydration with IV fluids. In severe cases, antibiotics may be helpful. The Centers for Disease Control and Prevention (CDC) reports that zinc treatment can speed the recovery of children infected with cholera.
9. Dengue Fever
Dengue can be a risk when traveling to tropical or subtropical areas. Mild forms of dengue can progress to dengue hemorrhagic fever, in which fluid escapes from the circulatory system and shock and death can occur. Dengue is carried by mosquitoes and there is no vaccine against this illness. Therefore, the best way to avoid contracting dengue is to avoid mosquito bites. When visiting subtropical areas, be sure to keep outdoor areas free of standing water, as this is where mosquitoes like to lay eggs. Use mosquito repellent and wear clothing with long sleeves to protect your skin.
8. Diabetic Ketoacidosis
Diabetic ketoacidosis occurs when a diabetic patient’s body lacks the insulin required to break glucose down to form the energy needed by the body. When this happens, the body begins to release ketones in order to break down fat instead of glucose. High levels of ketones in the blood can be poisonous, leading to coma or death. Large amounts of ketones can accumulate in the blood when a patient has been sick or has not injected the proper amount of insulin. It can also occur when a diabetic patient has not eaten enough food. Symptoms include dry mouth and thirst, frequent urination, fatigue, and nausea or vomiting.Related: 7 Most Common Symptoms of Diabetes
