The whole family is isolated at home, how can the child have a fever?

This question was seen in a comment today. Viruses, bacteria and mycoplasma are easily spread from person to person, so children who have just entered kindergarten are more likely to get sick. On the contrary, home isolation and reduced contact with people can greatly reduce the risk of infectious diseases. So long-term home isolation not only reduces the risk of new coronavirus infection, but also reduces the risk of flu, common cold, pneumonia and other diseases, and can also reduce some digestive tracts The risk of infectious diseases, which can make a child less likely to have a fever. However, reducing the risk of fever does not mean that there will be no fever. There are many possible reasons for the child to have a fever, in addition to the incubation period of some pathogens exposed before isolation. The spread of the virus mainly depends on person-to-person, not going out and not in contact with outsiders. Except for a few viruses that can be transmitted through animals, such as epidemic hemorrhagic fever, dengue fever, etc., the virus can hardly spread from home. Spread out to the family. But there are still people in the family, and some viruses can still be spread among family members, because some viruses can be carried on people asymptomatic for life, such as human herpes virus-6 that causes acute rash in young children , almost every adult carries it, as well as herpes simplex virus, varicella-zoster virus, etc. These viruses can be carried asymptomatically. If it is transmitted to a child, if the child just doesn’t have the corresponding antibody, it may become infected and cause fever. In addition, viruses are not the only pathogens that cause infection and fever. Bacteria and fungi can also cause infections, and they have their own energy metabolism systems, so they can survive for a long time outside the body, so they are not susceptible to human-to-human transmission. Dependency is not that great. For example, food can also be contaminated with Salmonella, Escherichia coli, etc. After eating it, acute gastroenteritis may occur, bacteria entering the urinary system may also cause urinary tract infection, and some skin diseases may appear if they are not well controlled Skin infections and soft tissue infections can also cause fever. There are also some children who have congenital malformations, such as intestinal malformations, urinary malformations, hydrocephalus, etc., are also relatively more prone to infection, leading to fever. . Come again, although infection is the main cause of fever, it is not the only cause. Although childhood tumors and immune diseases are relatively rare, they can also cause fever. Therefore, if you are isolated at home, your child may still have a fever, but it will be much less likely than going out every day to play with others.
