Why is summer easy to get some intestinal diseases?

Infectious diseases of digestive tract can occur all year round, but in midsummer, high temperature and high humidity accelerate the reproduction of bacteria and food is easily spoiled. In addition, people drink more water to dilute stomach acid, and at the same time, the hot weather makes people sweat more and sleep less, which leads to the decline of human immunity and makes pathogens take advantage of it.

In addition, a large number of fresh fruits and vegetables are on the market in summer, and they will inevitably be infected with pathogenic bacteria, especially Escherichia coli, in the process of growth, picking, transportation and sales. If eaten directly without cleaning, it is likely to cause digestive tract diseases such as diarrhea. The leftovers in the refrigerator have been stored for a long time, which also creates conditions for the reproduction of germs.

Food and water contaminated by pathogenic bacteria have not been thoroughly treated and disinfected, such as eating cold dishes and drinking raw water, which are the most common causes of typhoid and paratyphoid. There are many epidemics caused by water sources, mainly the collective water supply pipes such as drinking river water, lake water, pond water and tap water pipes are broken or improperly disinfected, and are contaminated by typhoid Bacillus. Close contact with patients' daily life can also cause infection, so pay attention to personal protection when taking care of patients.
