People often mistake influenza as a cold and don't pay attention to it, which can easily lead to serious illness and serious consequences. The main reason why they admit mistakes is that they have similar symptoms and are difficult to distinguish. Now let's learn about the main symptoms of influenza and the difference between influenza and common cold.
The main symptoms of influenza the difference between influenza and common cold
Main symptoms of influenza
The virus is not heat-resistant, inactivated at 100 ℃ for 1 minute or 56 ℃ for 30 minutes, sensitive to common disinfectants (1% formaldehyde, peracetic acid, chlorine containing disinfectant, etc.), sensitive to ultraviolet light, resistant to low temperature and drying, and can survive under vacuum drying or - 20 ℃. Among them, influenza A virus often occurs antigen mutation, infectious, spread rapidly, and prone to large-scale epidemic.
Typical clinical symptoms are: acute high fever, general pain, significant fatigue and mild respiratory symptoms. Generally, autumn and winter is the high incidence period, which causes serious complications and death. The disease is caused by influenza virus, can be divided into a (a), B (b), C (c) three types, a virus often occurs antigen mutation, infectious, spread rapidly, easy to occur large-scale epidemic. A H1N1 is also a type A. The disease is self limited, but in infants, the elderly and patients with cardiopulmonary diseases, it is easy to complicate pneumonia and other serious complications, leading to death.
The difference between influenza and common cold
Influenza is a viral cold. Viral cold is caused by virus infection, while cold is only caused by cold.
Viral cold is the upper respiratory tract infection, also referred to as Shanggan, is a common respiratory infectious disease caused by a variety of viruses. The causes include cold, rain, fatigue and malnutrition. The patient's nose, saliva and sputum contain virus, which can be spread into the air by sneezing, coughing and speaking, and infect others. Healthy people can also be infected with the virus due to contact with the patient's towel, washbasin or tableware. The main manifestations of cold are sneezing, nasal congestion, runny nose, dry throat, sore throat, cough, hoarseness and other symptoms. The general symptoms include headache, aching, fatigue, loss of appetite, or no fever, or low fever, or high fever, chills and other symptoms. The course of disease is generally 3-7 days.
Influenza is an acute respiratory infectious disease caused by influenza virus. The virus exists in the patient's respiratory tract and spreads to others through droplets when the patient coughs or sneezes. Influenza is highly infectious. Because this virus is easy to mutate, even people who have suffered from influenza will still be infected when they encounter the next influenza epidemic, so influenza is easy to cause an outbreak. Generally, there is more chance of epidemic in winter and spring, and 20-40% of people may be infected with influenza every time.
The difference between influenza and common cold
The symptoms of simple influenza are: sudden chills, fever, headache, body aches, nasal congestion, runny nose, dry cough, chest pain, nausea and loss of appetite. Infants or the elderly may have pneumonia or heart failure. Patients with toxic influenza are characterized by high fever, nonsense, coma, convulsions, and sometimes death. Therefore, the disease is very easy to spread, so it should be isolated and treated as soon as possible.
Influenza is a highly infectious respiratory infectious disease. Therefore, in areas where influenza is prevalent, gatherings or mass activities should be avoided. People should wear masks when they go out when influenza is prevalent to reduce the chance of infection. Open windows frequently for ventilation, wash clothes and bedding frequently.
For influenza patients, they should rest in bed, give food easy to digest and absorb, drink more water, and take compound aspirin (i.e. APPC), keganmin, Yinqiao Jiedu Tablets and other drugs. If you have high fever, you can give infusion of glucose and saline; if you have pneumonia, heart failure or coma and convulsions, you should give corresponding treatment.
