Because brain eating amoeba can cause fatal damage, Floridas Department of health has issued a reminder to Hillsborough County residents, asking local people - especially those who like to swim in rivers and lakes - to be alert to amoeba and avoid contact with water with their noses.
According to the BBC, brain eating amoeba generally appear in warm water, such as lakes, rivers, ponds or streams, and are most susceptible to infection in summer in July, August and September. Amoeba can enter the body through the nose, and the infected person may have fever, nausea, vomiting, neck stiffness, headache and other symptoms. Most of the infected people died within a week. However, there is no human to human transmission of amoeba.
According to the Centers for Disease Control and prevention of the United States, brain eating amoeba is relatively rare in the United States, and generally only occurs in some southern states of the United States. In the United States, there have been 143 cases of brain eating amoeba, of which only four survived.
