Nucleic acid detection is the most important means of "early detection" in epidemic prevention and control, and it is also an important defense line to strengthen self-protection. For your own safety, the health of your loved ones and the orderly operation of the city, please do personal protection and health monitoring, take the initiative to carry out nucleic acid detection, develop good habits such as washing hands frequently, using public chopsticks, being ventilated frequently and gathering less, wear masks correctly in public places, and actively cooperate with the temperature measurement.
However, if it is a high-risk area, according to the local epidemic prevention regulations, it may take two days, three days and five days to do a nucleic acid test. Even elderly people with mobility difficulties and farmers at the grass-roots level need to do nucleic acid testing when they don't go out at ordinary times, because not going out doesn't mean that they won't be infected with COVID-19, and there is still the possibility of indirect infection with COVID-19 due to contact with others or other items. Active nucleic acid detection is helpful to find the epidemic situation early and prevent its spread.
