The American epidemic is self-sufficient. Why did Legionella suddenly appear?

Because through the report released by the CDC, we know that once the building is closed for a period of time, it may lead to the breeding of Legionella.

We know that because the epidemic situation in the United States is very serious now, isolation and blockade measures have been taken in some areas, and some buildings have been temporarily closed, which may lead to the growth of Legionella during this period. Because when the buildings are closed, the water supply pipeline will also be closed, so the tap water stored in them will not flow as before, and chlorine ions and other disinfectants contained in the water may gradually evaporate. Therefore, if the tap water stays stagnant for a long time, the temperature may rise to 25~42 degrees Celsius, which is very suitable for the growth of bacteria, and Legionella is taking the opportunity to grow up at this time.

Legionella was found in the building rented by the CDC, and the emergency control center immediately took corresponding measures to deal with it. For safety reasons, they will not work until the Legionella in the building is completely cleaned up, and the office building will continue to be closed. However, it is not clear whether Legionella will aggravate the current epidemic, because the timely discovery of Legionella has not caused some impact on society. Do we know? Legionella is caused by the long-term closure of buildings, which have always been closed. Even if Legionella appeared in the water, it was not spread out for human use. Therefore, the emergence of Legionella did not put too much pressure on the American medical system.

But the United States must be vigilant, because even the buildings rented by the CDC in the United States have Legionella, which means that there may be closed factories, schools, restaurants and gyms in other places, and Legionella may appear. Therefore, all these buildings must be thoroughly inspected and must compete. If Legionella may cause great trouble in the later economic recovery of the United States, in mid-July, Cheng Juan, a resort hotel in California, also said that he had tested the tap water during the closure period, and found that the test result of Legionella competition was positive, and a school employee in Ohio was also found to have Legionella disease. Then it means that Legionella has begun to spread in American society, and we must control it in time before it spreads widely and causes most people to be infected.
