Malaria was founded in the 2700 BC-340 CE and it is spreaded by other humans to other humans but it is also spreaded by mosquitoes. Malaria started in Africa but later on moved to pretty much everywhere besides Antarctica. It started when scientist were studying parasites and then they happen to get the disease which ended up to be deadly. There was a health hazard during World War 2 for Malaria. There was a major out brake during the years of 1905-1910 and this was during the time of the construction of the Panama Canal (this is a epidemic). Malaria was a very effective disease way back about 10,000 years ago but now it is a very controllable disease and we have not had a breakout in at least 100 years because we have medicine for it.
