Will you get a stream B if you have a stream?
How to do a good job of personal protection.
It is also a respiratory infectious disease
What we need to pay attention to.
1. What is flow B.
Epidemic infection is an acute respiratory infection caused by influenza viruses. Influenza viruses can be divided into three types: A, B, and C. Influenza B is an epidemic caused by the influenza B virus.
The incubation period of influenza B is mostly 1 4 days.
Infected patients often have systemic symptoms such as fever (body temperature up to 39 40), headache, muscle aches, general weakness, loss of appetite, accompanied by respiratory symptoms such as cough, sputum, nasal congestion, runny nose, and sore throat. Gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea are more pronounced than those of influenza A.
Take anti-flu medications as soon as possible and don't put it off.
There is no difference between influenza B and influenza A, mainly with anti-influenza drugs, which can shorten the course of the disease. Take the medicine as soon as possible, if you take the medicine late, you will either get better, or it will become serious, and the effect will be greatly reduced.
It is recommended that patients with underlying lung diseases, immunodeficiency, diabetes, obesity, pregnant women, and patients on dialysis should go to the hospital as soon as possible.
Be sure to rest in time and don't procrastinate.
Repeated infection with mycoplasma, influenza A, and influenza B in a short period of time is related to low immunity and not recovering well, so it is important to pay attention to rest.
2. Will there be repeated infection if you have had influenza A or influenza B?
Influenza A and influenza B are two different subtypes of influenza that do not have a cross-immune mechanism. After influenza A or B infection, if the patient is relatively weak, there is still a chance of infection with another subtype of influenza virus.
It is unlikely that you will be infected with the same subtype of influenza virus within a year.
For example, if the A(H3N2) subtype of influenza A virus is currently circulating, and the patient will have immunity to this type of virus after infection, the probability of reinfection with the same type of virus within one year is small.
However, because influenza A viruses mutate easily, people who have not been vaccinated may be reinfected with other subtypes of influenza A viruses, but in recent years, because influenza B viruses have not mutated much, the spread range is relatively small, and the probability of reinfection with influenza B within a year is also small.
3. Is it reliable to take oseltamivir to prevent B flu?
Doctors recommend that physical means of protection should be the mainstay, supplemented by drug prevention. It is impossible to prevent people from gathering, you can't take medicine all the time, and wear a mask in a confined space. If a family member is infected with influenza B, wear a mask when in close contact with the patient; Other family members reduce their exposure to people with influenza B, especially children who are not infected.
Hands should be washed with detergent or disinfectant after direct contact with a sick person.
In view of the current prevalence of respiratory infectious diseases, it is necessary to increase or decrease clothes in time according to the changes in the weather, pay attention to balanced nutrition in diet, regular work and rest, do not overwork, enhance their own resistance, and get sick as soon as possible, and try to achieve early diagnosis, early isolation, and early **.
