Health Risk Warning
In October, the temperature in Hulunbuir City dropped, and the outdoor activities of the crowd gradually changed to indoor gathering activities, which is conducive to the spread of respiratory infectious diseases, and is suitable for the reproduction of some cold-tolerant pathogens.
1. Novel coronavirus
Although the number of cases of new coronavirus infection (hereinafter referred to as the new crown) in Hulunbuir City decreased in September, the temperature in autumn and winter is low, which is suitable for the survival and reproduction of the new coronavirus, and the general public needs to be vigilant against new crown infection in October.
At present, the main circulating strains of the new coronavirus in mainland China are the subclades of XDV and JN.1, which account for half of each strain. The new crown variants currently circulating in Hulunbuir are mainly XBB and JN series (JN.1, KP.2, KP.3). No significant changes in the pathogenicity of the various subclades of XDV and JN.1 have been observed. BA.2.86 and JN.1 are classified as "variants of concern (VOI)" according to the WHO classification of important variants, while the six subclades of currently circulating JN.1 are only VUM. The new variant that began to emerge from BA.2.86 has so far shown no evidence of an alteration in its pathogenicity.
Health tips: At present, the new coronavirus is still an Omicron variant, and like the prevention of infection with other Omicron variants, continue to maintain good personal hygiene habits, wear masks scientifically, adhere to regular work and rest, ensure a healthy diet, and improve the body's immunity.
2. Influenza
Influenza in Hulunbuir City still showed a low-level epidemic trend in September, but it has entered the influenza epidemic season since October, and it is recommended to strengthen influenza prevention as soon as possible.
Influenza is an acute respiratory infection caused by influenza viruses. Influenza viruses are easy to mutate and highly infectious, and the population is generally susceptible to influenza viruses, and the systemic symptoms are often obvious after infection, mainly manifested as acute onset, high fever, headache, muscle aches and fatigue. Children, the elderly, pregnant women, or people with chronic diseases such as asthma, diabetes, and heart disease are at high risk of severe disease after infection, which can lead to pneumonia, acute respiratory distress syndrome (ARDS), and multiple organ insufficiency.
Health tip: Getting vaccinated against the flu is the most economical and effective way to prevent the flu. Influenza viruses mutate easily, and the epidemic strains of influenza can change from year to year, so flu vaccination is required every year. Secondly, good hygiene and a healthy lifestyle can help reduce the risk of infection. Open more windows indoors for ventilation and frequent ventilation, and it is recommended to wear masks in public places. Try not to touch your mouth and nose with your hands, and try to avoid going in and out of crowded places. You can also exercise your body to boost your immunity.

Chickenpox is a respiratory infection caused by varicella-zoster virus (VZV) infection. The clinical manifestations are characterized by the appearance of pimples and herpes on the skin of the patient in batches, and the shape of the herpes is like a bean, and the color is clear and clear like blisters, hence the name.
