What virus is this epidemic in Weihai? (There is an epidemic in Weihai)

★ What are the characteristics of Omicron variants and how should the public guard against them?

The viral genome of this epidemic in our city was sequenced as Omicron. Omicron mutants have shorter incubation period, stronger infectivity and faster transmission speed. Studies abroad show that the intergenerational days of transmission are 2-3 days, and the transmission power is several times that of Delta mutant. Symptoms are not obvious. Many people have no symptoms, some of which are mainly non-specific symptoms such as fever, dry cough, headache, stuffy nose, fatigue and sore throat, which leads to its spread being very hidden and more prone to multiple sporadic or concentrated outbreaks.

The mutant strain of Omicron is still COVID-19. The route of infection is mainly respiratory transmission, but also through close contact and aerosol transmission. At present, epidemic prevention and control measures are still effective. Remind all citizens and friends to continue to do the following: First, maintain good personal hygiene habits, pay attention to hand hygiene, wear masks scientifically, ventilate frequently and gather less. Pay attention to keeping a "one-meter line" and cover it with a paper towel or elbow sleeve when coughing or sneezing. The second is to vaccinate the whole process. Vaccination with COVID-19 vaccine is the most effective way to prevent COVID-19, which can reduce the severity and mortality. Third, people who have an intersection with the case trajectory should take the initiative to report to their communities, hotels and work units after receiving health warning messages and abnormal health codes, and cooperate with the implementation of epidemic prevention policies.
