What is Swine Flu?

Yu Pengbo, director of the Viral Disease Prevention and Control Institute of the Shaanxi Provincial Center for Disease Control and Prevention, said A flu is short for influenza A and is an acute respiratory infectious disease caused by influenza A virus infection.

Influenza viruses can be divided into four types according to their core proteins: A, B, C and D. Influenza viruses that circulate seasonally in humans are influenza A (subtypes A H1N1 and A H3N2) and influenza B (Yamagata and Victoria) viruses.

Compared with influenza B virus, influenza A virus has many hosts in nature, and is more likely to mutate or remix, resulting in its rapid spread in the population, and many large-scale outbreaks of influenza in history have been related to influenza A virus.

Influenza patients and latent infections are the main sources of seasonal influenza infection. Influenza viruses are mainly transmitted by airborne droplets, but can also be transmitted through direct or indirect contact with mucous membranes such as the mouth, nose,

and eyes. Contact with items contaminated with the virus can also cause infection. In crowded and closed or poorly ventilated rooms, it can also be transmitted by aerosol.

What's the difference between the flu and the common cold?

Yu Pengbo introduced, first of all, the etiology of the two is not the same, influenza is caused by influenza virus, common cold is caused by rhinovirus, adenovirus and so on. Second, the seasonality is not the same, influenza has obvious seasonality (north of China from October to March of the next year),

the common cold seasonality is not obvious. Third, the symptoms are not the same, the typical symptoms of influenza are fever, body temperature can be as high as 39 to 40 degrees Celsius, can be accompanied by chills,

systemic symptoms, headache, muscle pain, fatigue and so on. Common cold generally does not have fever or mild or moderate fever, mainly nasopharyngeal symptoms, sneezing, runny nose, nasal congestion, sore throat, etc.,

systemic symptoms are mild or no. Fourth, the harm is not the same, influenza generally 3 to 4 days after the onset of body temperature gradually subsided, systemic symptoms improved, but the elderly,

children, chronic disease patients, pregnant women and other high-risk groups can be combined with pneumonia, otitis media, myocarditis and other complications, can develop into severe or even death. Complications of the common cold are rare and usually resolve in 5 to 7 days.

How should I treat the flu?

Ye Feng, chief physician of the infection department of the First Affiliated Hospital of Xi 'an Jiaotong University, said that after the occurrence of symptoms, it is recommended that patients rest at home and keep the room ventilated. Get plenty of rest,

drink plenty of water, and eat a diet that is easy to digest and nutritious. Minimize contact with others to avoid infection. The focus of treatment is to relieve influenza-like symptoms such as fever and cough, and patients should be closely observed for changes in their condition.

In case of persistent high fever, accompanied by severe symptoms such as severe cough, dyspnea, altered consciousness, severe vomiting and diarrhea, patients should seek medical attention in time.

Children under 5 years of age, the elderly, people with chronic diseases, pregnant women or obese people are more likely to develop serious complications, and should seek medical attention as soon as possible, under the guidance of a doctor to use antiviral drugs as soon as possible, the use of antibiotics and hormones are not effective against influenza viruses.

It is important to note that not everyone who has the flu has to take antiviral drugs. Most flu antivirals are prescription drugs and need to be evaluated by a doctor before they can be used. At present, the main influenza antiviral drugs available in China are oseltamivir, zanamivir, peramivir, abidol and mabaloxavir.

How to prevent the flu?

Ye Feng introduced that in daily life, maintaining good personal hygiene habits is an important means to prevent respiratory infections such as influenza. Wash hands frequently, keep the environment clean and ventilated; Minimize activities in crowded places and avoid contact with patients with respiratory infections;

Observe coughing etiquette; If you have flu symptoms, you should pay attention to rest; Wear a mask when going to public places or medical treatment. In addition, vaccination is the most cost-effective and effective means of preventing influenza,

and can be administered 1 to 2 months before the peak of influenza epidemics, and during the epidemic season when vaccines are available.New research "killing two birds with one stone" to solve the device application problem ‍
