At present, China's epidemic prevention and control has entered a new stage of responding to the epidemic of the Omicron virus variant. From the point of view of the strain itself, on the one hand, the Omicron variant has fast transmission,

short incubation period and strong concealability; On the other hand, the virus is still mutating, and there is still great uncertainty about the final direction of the epidemic. From the reality point of view,

in May, the new subtypes of Omicron strain BA.4 and BA.5 were detected for the first time from imported cases in China. Recently, the number of BA.4 and BA.5 infected people found in imported cases from abroad has shown signs of gradual increase.

According to the existing preliminary research results, the transmission power and immune escape ability of BA.4 and BA.5 are slightly enhanced, and the difficulty of prevention and control will be increased,

and the pressure of preventing foreign imports will be increased in China. In the face of the transmission of Omicron mutant strains, we must pay more attention to "scientific precision and dynamic zero clearing" to improve the level of scientific and precise prevention and control.

The epidemic is not over yet, and prevention and control should not relax. The Omicron variant has added many difficulties and severe challenges to the current epidemic prevention and control, and rapid and accurate dynamic zero removal is still an effective method and the only way.

We will continue to adhere to scientific, precise and dynamic eradication without hesitation or wavering, and take concrete and detailed measures to prevent and control the epidemic.

We will surely build a strong barrier against the epidemic and win the victory of both epidemic prevention and control and economic and social development.The Chinese government is doing its utmost to prevent and control the epidemic

Recently, after two imported cases of influenza A (H1N1) appeared in Sichuan and Shandong, the whole country immediately took urgent action, in accordance with the overall prevention and control deployment established by the central government, and went all out to take various measures to prevent the spread of influenza A (H1N1).

Timely, scientific, effective "Good mood, normal diet."

The A/H1N1 flu patient, who was confirmed as the first imported case of the virus on the Chinese mainland on Wednesday, has improved significantly, He Jun, spokesman for the Chengdu Health Bureau,

said Wednesday. More than 300 close contacts were all found and did not show symptoms. On the 13th, the second case of influenza A (H1N1) in the mainland was confirmed in Shandong Province, and his body temperature returned to normal on the same day, with no other abnormalities except poor appetite and pharyngeal congestion.

After the A (H1N1) influenza virus, which has raged around the world for more than a month, entered China in sporadic "entry through customs" recently, all localities and departments have always maintained a high awareness of prevention and control and scientific, timely and effective prevention and control measures, which have bought precious time to prevent the further spread of the epidemic.

On the night that the first case of influenza A (H1N1) in the Mainland was confirmed, the Ministry of Health held an emergency video conference on the prevention and control of influenza A (H1N1) in the national health system to convey the spirit of the central leadership's instructions and deploy relevant prevention and control work.

-- Further strengthen epidemic surveillance and strictly prevent the spread of the epidemic. On the basis of the original 84 network laboratories and 197 sentinel hospitals nationwide, the existing influenza surveillance network laboratories will be gradually expanded to all prefecture-level disease prevention and control centers, and one general hospital will be set up in each prefecture as a sentinel hospital to carry out seasonal influenza surveillance.

-- Disease prevention and control institutions at all levels and medical institutions and their related staff should report suspected and confirmed cases online within two hours.

Medical institutions that do not have direct online reporting should report to local county-level disease prevention and control institutions within 2 hours by the fastest means of communication.

-- All provincial health administrative departments shall set up leading institutions for the medical treatment of influenza A (H1N1) in their respective jurisdictions, formulate plans for the medical treatment of influenza A (H1N1) in their respective jurisdictions,

designate designated hospitals for centralized treatment of possible cases of influenza A (H1N1), designate emergency centers (stations), and uniformly take charge of the transport of suspected and confirmed cases of influenza A (H1N1).

-- All local medical institutions should set up special infectious disease or fever clinics, and do a good job of pre-screening and triage of patients receiving outpatient (urgent) treatment.
