4 Deadly Killers by: Nick Taylor
Malaria (Plasmodium Falciparum)
Botfly Larvae (Gasterophilus Intestinalis)
Schistosomaiasis (Schistosoma mansoni)
Schistosomaiasis has the second highest infection amount at 250 million people. The disease is spread by contact with water that contains the parasites. These parasites are released from snails that have been infected. The disease is especially common among children in poor countries as they are more likely to play in infected water. Other high risk groups include farmers, fishermen, and people using infected water for their daily chores. A way you can know you have this is by finding the eggs of the parasite in a person's urine. This, in humans, mostly affects the digestive and sometimes the respiratory system.
