The wake of the insects has passed, and the spring equinox is approaching. The spring of recovery of everything has quietly entered people's lives. However, the temperature is unstable, and the temperature difference between day and night is large. At the same time, the COVID-19 continues throughout the country. Here, Chaineng editor and QATM metallographic consumables warmly remind everyone to always pay attention to preventing the spread of infectious diseases.


I believe that all the small partners have also noticed that in the near future, the situation of the surrounding international and domestic COVID-19 epidemic is relatively serious, and the inbound cases and the local epidemic have also increased recently. The prevention and control work of COVID-19 cannot be relaxed. We must continue to take precautions and pay attention to personal safety. Chaineng editor and QATM metallographic consumables suggest that everyone do the following:


1. Enhance personal protective awareness. Adhere to good personal hygiene habits such as frequent hand washing, wearing masks, constant ventilation, less gathering, using public chopsticks, and serving of individual dishes. Once symptoms such as fever, dry cough, and fatigue occur, it is necessary to seek medical attention in a timely manner according to standardized procedures, and proactively inform the patient of their 14 day activity trajectory and contact history. Wear a mask throughout the medical journey and avoid taking public transportation.


2. Active vaccination against COVID-19. Please follow the arrangements of the community or unit, strictly follow the immunization procedures, and receive the vaccine on time and in sequence.


3. Adhere to the principle of not leaving the country unless necessary, not going to medium to high risk areas, and areas with local cases of COVID-19.


4. Adhere to normalized epidemic prevention and control measures. Winter and spring are the high incidence seasons of respiratory infectious diseases, and it is necessary to adhere to wearing masks in crowded places and enclosed spaces. Wear masks scientifically and maintain a distance of at least 1 meter when in contact with people.
