On January 20, a strong cold air will hit Guangdong, and the lowest temperature in Guangzhou will drop to about 10℃. While people were digging out their down jackets one after another, they were also frightened by the online rumors that “Bi Liu is fierce”. Don’t panic! According to the Guangdong Provincial Center for Disease Control and Prevention, Guangdong is still dominated by influenza A. It is recommended to do these two things well to easily cope with the “cold air arrival”.
High-risk groups should pay attention to personal protection
Since the beginning of winter, respiratory infectious diseases have been common in winter. Viruses such as influenza and Mycoplasma pneumoniae have become popular at the same time and have been on hot searches many times. The National Health Commission press conference on January 14 stated that the current respiratory diseases are still dominated by influenza.
What is the specific situation in Guangdong? On the evening of January 16, an expert from the Guangdong Provincial Center for Disease Control and Prevention said: “At present, influenza is still the main disease, and influenza A is still the main disease in our province.”
There are rumors circulating on the Internet that influenza B is a ferocious disease. Some people are confused about the fact that a child infected with influenza A happens to be infected by influenza B. There is also a saying that influenza B is the ‘king of kings.’ Is it true that influenza B is more serious than influenza A? ?
Experts from the Provincial Center for Disease Control and Prevention responded: “Influenza B is the same as influenza A! They are both highly contagious, fast-spreading acute respiratory infectious diseases caused by influenza viruses, and the entire population is generally susceptible.” With sneezing, Unlike the common cold, which is dominated by nasal congestion, runny nose, and cough, influenza can cause a high fever with a rapid rise in body temperature in a short period of time, pain, fatigue, and more obvious systemic symptoms.
It should be noted that in the same influenza epidemic season, different types and subtypes of influenza viruses usually co-circulate. Even if people have been infected with influenza A, they may be infected with influenza B again. High-risk groups such as children under 5 years old, elderly people over 60 years old, patients with chronic diseases, and pregnant women are more likely to develop serious complications and should pay attention to personal protection.
Coping with strong cold air: Keep warm and cold, beware of colds
In the face of the coming strong cold air, disease control experts remind us to pay attention to keeping warm and prevent colds.
1. The cold wave is coming and the temperature is changing. The public should try to reduce outdoor activities as much as possible and avoid working or doing activities outdoors for a long time. Children, pregnant women, the elderly and patients with cardiovascular, cerebrovascular and respiratory diseases should reduce outdoor activities and go to crowded places as little as possible.
2. As long as the outdoor air conditions permit and the individual is well-kept warm, attention should be paid to opening windows for ventilation, preferably once in the morning, noon and evening.
3. Keep warm when going out, and carry and use hats, gloves, scarves and other thermal supplies.
4. Maintain a regular life schedule, exercise moderately, eat a balanced diet, and balance work and rest.
5. If you use gas or coal stoves to keep out the cold, be sure to pay attention to indoor ventilation to prevent carbon monoxide poisoning; when using heating tools such as small suns, be sure to turn off the power in time to avoid fires.
The first thing to do to prevent the flu: get vaccinated
Guangdong Provincial Disease Control and Prevention experts pointed out that influenza vaccination is the most effective way to prevent influenza and can significantly reduce the risk of serious complications in vaccine recipients.
Priority is given to recommending the following eight key and high-risk groups to receive influenza vaccines in a timely manner:
1. Medical personnel, including clinical treatment personnel, public health personnel, health and quarantine personnel, etc.;
2. Seniors aged 60 and above;
3. People suffering from one or more chronic diseases;
4. Vulnerable populations and employees in elderly care institutions, long-term care institutions, welfare homes and other crowded places;
Children aged 6.6~59 months;
7. Family members and caregivers of infants under 6 months old;
8. People in key places such as child care institutions, primary and secondary schools, and supervision places.
In addition, if the elderly have underlying diseases, especially those with chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), experts also recommend vaccination against pneumococcal vaccines, which can effectively prevent secondary infections.
The second thing to do to prevent influenza: take precautions
To prevent influenza, personal protection such as washing hands frequently, ventilating frequently, wearing masks, covering mouth and nose, and avoiding gatherings are indispensable. During the current influenza epidemic season, high-risk groups such as the elderly, children, pregnant women, and patients with chronic underlying diseases should avoid going to places where crowds gather and have closed spaces as much as possible. If they must go there, they should wear masks.
