Recently, the ** Meteorological Observatory released a message that due to the impact of the cold wave, most parts of China will have "cliff-like" cooling weather. Around the end of this week, temperatures in the central and eastern regions will enter a real trough period, with highs and lows from north to south. The maximum temperature in most of the north was below 0, and it was freezing all day.
The cold wave "King Bomb" is coming, in addition to keeping warm, anti-cold, anti-flu, are you ready?
Correctly distinguished, the common cold and flu are very different
In life, people often encounter symptoms such as nasal congestion, runny nose, cough, sore throat, etc., and they will invariably say "I have a cold". Actually, this statement is not accurate, and the symptoms may also be infected with the flu virus.
The common cold and the flu can be distinguished from two major aspects.
First, the pathogens are different
The common cold can be caused by a variety of pathogens, among which viruses are the most common, including rhinovirus, adenovirus, metapneumovirus, bocavirus, etc., and bacteria and mycoplasma can also be caused.
Influenza is an acute respiratory infectious disease caused by influenza viruses, which can be divided into four types: A (a), B (b), C (C) and D (D), among which influenza A (H1N1 subtype and H3N2 subtype) and B influenza virus cause seasonal epidemics every year. The latest influenza surveillance on December 7 showed that the influenza viruses in the southern and northern provinces of China were mainly A(H3N2) subtype.
Second, the symptoms are different
The symptoms of the common cold are mild, and there is no fever or low-grade fever;Cough is a common clinical symptom, but also often manifested as sneezing, nasal congestion, runny nose, etc., and systemic symptoms such as headache, body aches, chills, fever, etc. are mildThere are generally no serious complications.
Influenza generally has an acute onset, fever (body temperature can be as high as 39-40), and patients often have severe systemic symptoms such as chills, chills, headache, muscle and joint aches, fatigue, and loss of appetite. In addition, a small number of severe patients may develop complications such as rhabdomyolysis, pneumonia, encephalitis, and encephalopathy.
Keep in mind the "tips" to keep warm and maintain respiratory health
The temperature has dropped due to snowfall, and the outdoor body feels cold, so everyone needs to pay attention to the weather forecast in time and pay attention to cold and frost protection.
Early flu vaccination is an effective way to prevent influenza. Recently, the China Disease Control and Prevention issued health tips for winter influenza vaccination, making it clear that the current season is high for influenza, and for people who have not been vaccinated before, vaccination is still effective, and it is recommended that everyone get vaccinated as soon as possible.
For the common cold, there is no preventive vaccine, and the body can only improve its immune function by strengthening the body to resist the invasion and damage of the virus.
In addition, health protection is essential. Frequent handwashing is an important measure to prevent influenza. Wash your hands with soap and running water for at least 20 seconds, and avoid touching your mouth, nose, eyes, etcEat reasonably, maintain indoor air circulation, avoid contact with infectious sources, try to avoid contact with infected patients, wear masks if you must come into contact, and keep your distance;If someone in the family is infected, it is advisable to isolate as much as possible.
Anti-cold, anti-flu, family standing Lianhua Qingwen
Colds and flu are the most common respiratory infections in winter. Under the attack of strong cold air, it is more likely to be infected with the risk of "pricking".
Experts say early use of anti-flu drugs early in the flu can significantly reduce the chance of severe disease and death. If you have flu symptoms such as fever, sore throat, cough, and muscle aches all over the body, it is important to take medication in time and treat the symptoms.
As for the selection of anti-influenza drugs, the "Epidemic Diagnosis and Treatment Plan (2020 Revised Edition)" issued by the National Health Commission has given detailed references, such as neuraminidase inhibitors in Western medicine and Lianhua Qingwen in Chinese patent medicine are effective choices. In particular, a number of clinical studies have confirmed that Lianhua Qingwen can shorten the duration of influenza symptoms such as fever, cough, muscle aches, fatigue, headache and other flu symptoms in influenza patients, and has the overall advantages of antipyretic, anti-inflammatory, reducing upper respiratory tract symptoms, and regulating immunity more than a single antiviral drug.
Therefore, in the face of this round of "king bombing" level cold wave invasion, for colds and flu with the family medicine box as the main counterattack position, it is recommended to keep Lianhua Qingwen at home, and take it as soon as possible when symptoms appear, so as to play an early inhibitory role.
Warm reminder, the risk of cold and flu is high under the cold wave, please increase or decrease clothing in time according to weather changes, and do a good job of effective protection. Once infected, it is advisable to seek medical attention as soon as possible if the symptoms are severe or if there are other underlying medical conditions.
