Novel coronaviruses can spread in hot and humid climates, and signs of transmission have been found in hot, humid and dry countries. Therefore, it can be judged that the new coronavirus is not very restricted by weather and is not afraid of hot and humid weather. Therefore, until a vaccine and drugs are developed, the most critical measure is to eliminate the source of infection and cut off the transmission route. The general public should try to cooperate with the state’s appeal and go out as little as possible. For workers who have returned to work, they should take precautions by washing their hands regularly, wearing masks, keeping a distance from other people, avoiding crowds, and taking good personal protection.
