Influenza

Winter is the season of high incidence of respiratory infections such as influenza. At present, the country's influenza is in a high incidence state, and it is expected that in the next period of time, the intensity of influenza virus activity in this city will be at a relatively high level. Raise awareness of disease prevention, strengthen health protection, and maximize prevention of infectious diseases such as influenza.

Many people often confuse flu with the common cold, but in fact they are different in symptoms and causes.

common cold

1

Early symptoms include dry, itchy or burning throat, sneezing, nasal congestion, and runny nose. It thickens after 2 to 3 days and may be accompanied by sore throat.

2

Generally, there is no fever and systemic symptoms, or only low fever and headache. If there is no concurrent bacterial infection, it usually recovers within 5-7 days.

3

The common cold in adults is mostly caused by rhinovirus, followed by coronavirus, respiratory syncytial virus and so on.

 

influenza

1

Sudden high fever, headache and discomfort, severe systemic symptoms or respiratory symptoms. Initially it can be manifested as chills, chills, high fever, body temperature can reach 39 ℃ -40 ℃, accompanied by headache, body aches, weakness, and often have sore throat, dry cough, may have nasal congestion, runny nose, post-sternal discomfort Wait.

2

Some patients have symptoms such as sneezing, chest pain, nausea and vomiting, and abdominal pain and diarrhea. Sometimes accompanied by facial flushing, conjunctival congestion.

3

Influenza is caused by influenza virus, spread through droplets and close contact, the population is generally susceptible, highly contagious, and often has an obvious epidemic.

 

 

Three main reasons for the high incidence of flu

1

The temperature is too low: when the cold air is suddenly attacked, the human nasal mucosa is stimulated, and the ability to resist the invasion of external bacteria is reduced; cold air will also promote the activity of the bacteria.

2

Dry climate: People with chronic respiratory diseases, if the air humidity is too low, it is easy to cause sputum thick or dry scab is not easy to discharge, the stored sputum has become a breeding ground for viruses and bacteria, thereby further aggravating the infection.

3

Poor indoor ventilation: In winter and spring, most people don't open windows often for ventilation, and indoor pollution is dozens of times higher than outdoor.

 

According to the biological characteristics and transmission routes of influenza virus, to prevent influenza, it is recommended that you do the following:

Vaccination against influenza: Influenza vaccine can effectively prevent influenza and is one of the main measures to control influenza. In my country, the time to vaccinate flu is generally from September to November each year, because winter is a frequent season of influenza. Vaccination before the outbreak of influenza can help the vaccinated people to protect them to the greatest extent.

Pay attention to personal hygiene: Wash hands frequently-use soap/hand soap and wash your hands with running water to prevent the spread of bacteria and viruses, especially when you have been to public places and other crowded environments or your hands are in contact with respiratory secretions. handwashing. Cover your mouth and nose with a handkerchief or tissue when sneezing or coughing to avoid infecting others with droplets.

Pay attention to the ventilation of the window: as soon as the winter enters, the temperature becomes colder, and everyone starts to resist the style of the window. Especially in recent years, there has been frequent smog, and even fewer people are willing to open windows. As everyone knows, it is these factors that create the perfect conditions for the spread of the virus.

Strengthen resistance: If the resistance is good, the disease will not be easy to find. Strengthening physical exercise and maintaining adequate sleep are all well-known ways to enhance resistance, but many people ignore it, and resistance can be supplemented by "eating."

For example, onions and garlic have strong sterilization and disinfection effects, which can help the body prevent flu; white radish contains a large amount of organic sulfur compounds and rich vitamin C, trace elements zinc, can enhance the body's cold resistance.

Moderate dressing: Winter dressing is also a particular thing, too much is not good. First of all, we all know that wearing too little clothes on a cold day can easily catch cold and cold, giving colds an opportunity. But wearing too much and too thick will often sweat, after the sweat blows the wind is more likely to catch cold. Therefore, it is best to wear an appropriate amount and bring a coat with you, and add or subtract according to the environment and occasions.

Viruses have poor survivability in the outside world. They are afraid of ultraviolet rays in the sun, cleanliness, and dryness. In the fresh air, viruses will quickly die. Therefore, opening windows frequently in school or home environment can greatly reduce the risk of influenza infection.

Of course, the most important thing to enhance resistance is to have a balanced diet, strengthen exercise, and avoid excessive fatigue. Drinking more water is also a very good health care method.

Kangfeng launched a CADR900 household air purifier for particulate matter. The sterilization rate is >99.99% (30 cubic meter cabin) for 30 minutes. Its biggest bright spot is that home use can reduce the incidence and cross-infection of respiratory infectious diseases in susceptible people such as the elderly and children. A total of six gear speeds, a silent CADR250, and a second gear CADR of 390. The formaldehyde CADR is not high and only 200, CCM>F4. The volume is 378×375×775mm, the weight is 14.5kg, and the power is 95 watts. Its air disinfection effect exceeds that of professional medical disinfection machines currently on the market.
