Scrub insects are also very violent, and there have been incidents of scrub insects biting people to death. Recently, there is also a high incidence of scrub insects, so everyone should avoid playing in some grass and bushes.

Mobilize the masses to remove rotten wood, waste materials, and weeds around the houses, and destroy the habitats and breeding grounds of cryptopteryx. Do not pile up waste items indoors, keep the room clean and tidy, so that there is no hiding place for cryptoptera insects that invade the room. Units that need to work at night in summer should install screen doors and windows to prevent nocturnal insects (including cryptoptera) from flying into the room and reduce the chance of human contact with cryptopterus.

(2) Periodicity, but not obvious.
and (3) the relationship between pathogenesis and meteorological factors
The disease is more common in seasons with high temperature, high humidity, high rainfall, and low air pressure. According to the incidence of the disease in Nanchong and Chongqing for many years, the disease often breaks out in years of continuous high temperature and drought and continuous autumn rain.
