The latest monitoring results of China CDC show that acute respiratory infectious diseases in China are on the rise, mycoplasma virus and syncytial virus are still at a high level, and influenza has also entered a seasonal epidemic period, and the positive rate has increased significantly, but it is still lower than the same period last year. November to March every year is the high-incidence season of influenza in northern China. This year, the high-incidence period in Beijing came late, and it began to enter the epidemic season in December. The main strain in this epidemic is influenza A H1N1.
When the weather just turned cold, there were more mycoplasma infections. With the flu season, especially after December, the number of flu cases increased significantly. At present, the main popular respiratory diseases include influenza, mycoplasma, chlamydia, rhinovirus, syncytial virus, human metapneumovirus, etc. These diseases have the possibility of cross-infection. A person may be infected with multiple respiratory diseases at the same time, because after getting the flu or mycoplasma, the protective ability of the respiratory tract will decrease, and it is easy to have superimposed infections.
At present, only influenza has vaccine. It is suggested that the elderly, infants, pregnant women, patients with basic diseases, obese people and other people with low immunity should be vaccinated with influenza vaccine to reduce the risk of serious illness and complications. Recently, some citizens reported dizziness after being infected with the flu, but the relevant departments said that no new strains of respiratory infectious diseases had been found. Different individuals have different symptoms of respiratory virus infection, such as dizziness, headache, fatigue and muscle soreness, which are the self-protection mechanisms of the immune system after recognizing the virus.
Antiviral drugs for influenza have the best effect within 48 hours after symptoms appear, which can shorten the course of disease and reduce the risk of severe illness. You can always keep antipyretic and analgesic drugs at home, but you need to follow the doctor’s advice to avoid repeated medication. If the patient has persistent high fever, severe cough, breathlessness, listlessness and other symptoms, or still does not improve after 5 days of onset, he should seek medical advice in time.
In recent cases aged 14 and below, human metapneumovirus infection showed a fluctuating upward trend. This virus can cause acute respiratory infection, the main symptoms include fever, cough, runny nose, etc., and the incubation period is usually 3 to 6 days. At present, there are no vaccines and specific drugs, and most of the treatment measures are symptomatic support treatment. Human metapneumovirus is more common in autumn and winter, and it is less likely to cause severe illness. Preventive measures include washing hands frequently, wearing masks, and avoiding crowded places or closed spaces.
Different respiratory diseases have different infection symptoms. After the onset of influenza, there will be respiratory symptoms such as fever, sore throat and cough, as well as systemic symptoms. The course of the disease is usually 5 to 7 days. Mycoplasma infection is mainly caused by cough, and the fever is not obvious or low-grade, and the course of disease is long, which can last for more than one month in severe cases. After syncytial virus and rhinovirus infection, the main symptoms are cough, sneezing, stuffy nose, fever and sore throat, and the symptoms generally improve after one week. The severity of these diseases is different between adults and children. Adults often suffer from influenza more seriously than mycoplasma, while children are more likely to develop severe mycoplasma infection.
