In the face of the virus, in fact, very small, but always found after the injury, why not do a good job in prevention?
Mixed with waves of coughs and crying, this year's flu came menacing: some schools announced an emergency suspension of classes, major hospitals in the country have been squeezed out of pediatrics, and even the hospital's pediatricians to work overload to all the sick, and helpless Closure.
On January 17, Academician Zhong Nanshan, director of the National Center for Clinical Research of Respiratory Diseases, interpreted the characteristics of this year's influenza and pointed out that there are some variations in the current epidemic of influenza B virus. However, at present, the trivalent influenza vaccine used in China fails to cover this virus Subtype.
Academician Zhong Nanshan also said that there may be a new wave of influenza coming in March and urged relevant departments to make preventive measures and to promptly produce the tetravalent vaccine against the flu. Only with early prevention can fewer children be left behind Suffer, parents must be careful to understand.
1, why the recent influenza so presumptuous?
The recent outbreak of the flu is caused by a combination of factors. Winter has always been a period of high incidence of influenza, coupled with the dominant strains of this year (B) has not become the dominant strains for many years, the population lacked immune barrier, increased susceptibility to the crowd.
Zhong Nanshan Academy of Sciences in interpreting the characteristics of this year's flu said:
1, according to the nuclear protein, influenza can be divided into A, B, C, D four major antigen type, including A, B are two common;
2. Since April 2017, there was no significant variation in the prevalence of Influenza A (H3N2), Influenza A (H1N1) and Influenza B (Influenza A) in our country. However, Influenza B virus mutated from the end of last year to the beginning of this year. Influenza B Yamagata type significantly increased .
3, the existing match of B vaccine can not keep up, failed to play a preventive role for the current wave of this crowd , the population of the new virus is lack of immunity , so the number of doubled.
National Health and Family Planning Commission held a routine conference recently also pointed out:
The prevailing predominant strain is influenza B Yamagata, which has not been widely spread over many years, leading to a lack of immune barrier in the population and an increase in susceptible populations.
In response, Zhong Nanshan said "the flu is still an unpredictable threat to us." Because the strain of the flu is not static, it is very cunning that it can keep evading the population from its immune attack.
2, why March may usher in a new wave of flu?
On the afternoon of January 17, when interpreting the characteristics of this year's influenza, Academicians Zhong Nanshan repeatedly reminded: In March this year, a new wave of influenza may emerge and vigilance must be heightened.
"What we are most afraid of now is the bird flu and the human flu. If the problem of mixing is bigger, we must be very vigilant." Academician Zhong Nanshan said that in accordance with the prevailing laws in previous years, the H7N9 bird flu virus was concentrated in January-March. The current epidemic of influenza B virus, if at the same time in March outbreak, will be a kind of situation?
He went on to explain that so far no virus or pathogen has evolved as rapidly as the flu virus, and that the flu virus has the ability to spread across species, once crossed the species barrier, is likely to have a serious impact on public health security.
Fever, headache, muscle aches, dry cough, sore throat and tiredness are classic flu symptoms. Some people also have pain in their eyes and joints. Children also experience vomiting or diarrhea.
3, trivalent vaccine is also effective for the new virus subtype?
There is no doubt that vaccines are the best way to reduce the probability of infection. Many parents take this approach to help prevent influenza. However, the trivalent flu vaccine currently used in our country can not cover this type of influenza B, that is to say, now The vaccine does not match the current virus .
However, it is still necessary for us to vaccinate the trivalent vaccine because the influenza virus can not be completely touched. Perhaps the next three waves will turn the other three (A, C and D) viruses into turns.
In addition, the country is planning to produce a tetravalent vaccine and is expected to go public in the second half of the year. Four-valent vaccine is based on the trivalent, the now popular anti-influenza B added. Vaccine to be effective two weeks, I remember before the outbreak of flu injection.
Although trivalent vaccine is not effective in prevention of "Influenza B Influenza" currently, it can still play a preventive role for other influenza.
4, once the flu symptoms to eat what medicine?
"In the early stages of the outbreak, the use of anti-influenza drugs can reduce the spread of the virus," Zhong Nanshan said.
National Health and Family Planning Commission have also released the latest version of "influenza treatment program," the program clearly recommended a number of anti-influenza virus drugs, including oseltamivir, zanamivir, peramivir, even Huaqing plague capsules and suitable for children to use child resistant and susceptible particles, pediatric drum Alice heat particles, antelope horn powder and other antiviral drugs.
Among them, Zhong Nanshan according to clinical experience, said:
Early treatment with oseltamivir within 48 hours of developing flu-like symptoms does help relieve fever and other symptoms and reduce the risk of pneumonia, and Lianhuaqingwen Capsulehas the same effect of shortening the course and reducing the viral load .
In addition, parents should pay attention to these 3 drugs are no longer recommended to use, including the resistance to a drug amantadine and rimantadine, was sold out of stock of Radix is also referred to the cold is invalid, may also need Do further medical research.
5, refuse influenza you have to do what?
① wash their hands: hands easily stained with viruses, and then touch the nose and mouth caused by infection, in addition, you may like to wash your hands after a towel to dry, in fact, the towel is easy to latent bacteria, it is best to use disposable paper towels or choose to dry naturally.
② keep the environment clean and ventilated: keep the indoor clean, keep the ventilation, maintain proper dry, can prevent the breeding of bacteria and viruses.
③ to protect the mouth and nose: reduced to densely populated places, you must remember to go out to bring masks to children, so that it can effectively protect the mouth and nose are not infected by the virus.
④ good habits of the nose and mouth: cough, sneeze, cover the nose and mouth with a tissue, and then remember to wash their hands and avoid touching the eyes, nose and mouth to prevent the virus from invading the body from elsewhere.
⑤ hot foot bath: foot bath can promote blood circulation, speed up the body row of cold, people in the warm state, not easily hit by the virus.
Write in the end
Flu outbreak is only a matter of time, and you do not know the next will be more violent, because no one can predict the virus will evolve into what it looks like, parents can do is to make a good knowledge of reserves more bottom, and daily routine preventive measures Reduce the damage!
Last reminder, if the children in the house move, please take care of their children's family members are wearing masks, because this year's flu virus is really amazing, please let all parents know: Only adults are not sick, can take good care of children.
