Water samples taken from Burger’s Lake in Fort Worth have tested positive for Cryptosporidium, the water-born parasite that can sicken people for to two weeks, health officials said.
Officials have eliminated environmental factors as a likely source of the outbreak, according to a statement from Tarrant County Public Health. The most likely source was an infected swimmer going to the bathroom in the lake.
The test was performed by the Centers for Disease Control and Prevention in Atlanta, Ga.
The lake’s owner voluntarily closed the lake last week after several people had visited the lake were diagnosed with the parasite. On Wednesday, health officials said they have confirmed 20 cases of Cryptosporidium. Three people had to be hospitalized, officials said.
