“A total of 444 cryptosporidium infections have been reported in more than 40 states of the United States and Puerto Rico , which is an autonomous federal district, from 2009 to 2017. It is announced that 7465 people will rise.

Cryptosporidium is a type of protozoa that uses a wide range of vertebrates as its host, and infects humans through the fecal-oral route that is transmitted from the mouth via feces . The most common route of infection with Cryptosporidium is the pool, and about a third of the total was from recreational water including the pool.

When a person is infested with this

cryptosporidium, it develops cryptosporidiosis and causes symptoms such as diarrhea. In addition, it is said that this cryptosporidium-infected person releases up to about 100 million eggs in a single diarrhea and about 1 billion eggs (ocysts) in one day. And if only 10 of them enter the mouth, they will be infected with high probability.

Another complication is that cryptosporidium is highly resistant to chlorine. It is possible to survive for up to 7 days in a properly chlorinated pool. According to a survey conducted by the CDC in 2013, it was also found that 58% of the water collected from the public pool was contaminated with human faeces. 'Please do not enter.'

In addition to infection by water such as pool, it is reported by CDC investigation that there are 86 cases of infection by contact with animals and 57 cases of infection by child care. It is thought that child-rearing infections are second only to animal infections because people in child-rearing have many opportunities to contact the excreta of children who have been infected with Cryptosporidium by changing diapers.

The CDC states that 'Monthly cryptosporidium was the most common in July and August,' calling for the need to be especially aware of infectious disease measures in the hot season.
