The spread and prevention of varicella in China

The varicella-zoster virus (VZV), a common infectious disease in children, is the cause of varicella, a highly contagious illness. The infectious disease is more prevalent in youngsters, although it affects adults, pregnant women, and people with impaired immune systems more severely. The illness frequently manifests as itchy blisters and scabs, and it may start with a low-grade temperature and pain. Understanding the infectious mechanisms that contribute to varicella and the fundamental prevention actions is therefore essential. This essay will study the relationship between Varicella infectivity and temperature in meteorological factors as well as gender and age in personal factors through the way of paper review, and propose that the most common preventive measure is the way of vaccination. Finally, the result of the study is that the infection is indeed related to the change in temperature, and the temperature change in different regions makes the infection situation of Varicella at different temperatures different. In addition, Varicella infection is particularly high in infants and young children with low immunity, and the infection rate is slightly higher in men than in women.
