Since November, disease control departments in Yunnan, Guangdong, Sichuan and other regions have successively issued notices reminding that respiratory infectious diseases such as chickenpox have entered a high incidence period. The disease is highly contagious and prone to outbreaks in schools, daycare institutions and other places. It is necessary to prepare for the outbreak of chickenpox and pay attention to scientific prevention. How is chickenpox transmitted? How to identify and prevent? How to avoid being infected when someone around you is infected? How to get vaccinated? China News Network interviewed relevant experts on this matter. 01 Highly contagious herpes zoster patients can also be infected. The Chinese Center for Disease Control and Prevention has issued an article introducing that chickenpox is an acute respiratory infectious disease caused by the chickenpox zoster virus, which is highly contagious and can occur throughout the year. It is more common in winter and spring. Li Dong, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital affiliated with Capital Medical University, once told China News Network that the incubation period of chickenpox is relatively long in infectious diseases, usually between 10 and 20 days. Most patients develop symptoms around two weeks after exposure to the virus. There are two main ways of transmission, one is through air transmission, which is transmitted through secretions in the patient's respiratory tract; The second is indirect transmission through direct contact with the patient's herpes fluid or contact with contaminated items. He reminded that after recovering from chickenpox, there may be latent chickenpox zoster virus in the body, which can recur in the future when the immune system declines, causing shingles. Although herpes zoster is not transmitted through the respiratory tract, the patient's herpes fluid also contains viruses that are contagious. Some children who have not suffered from chickenpox or have been vaccinated against chickenpox may also become infected with chickenpox after coming into contact with herpes zoster patients at home. What are the clinical manifestations of chickenpox that can be cured in about two weeks due to the difficulty in distinguishing early symptoms? How to identify early on? How long can there be no contagiousness after being infected with chickenpox? Li Dong once said that generally, after about 2 weeks of onset or when all herpes has scabbed and no herpes fluid, it can be considered non infectious. He pointed out that patients with chickenpox may experience symptoms similar to a cold or flu in the early stages of the disease, such as fever, headache, fatigue, muscle soreness, etc. It is difficult to distinguish in the early stages, and identification requires asking the patient's epidemiological history. However, rash usually appears on the day of fever or one or two days later. Initially, it is a red maculopapule that quickly develops into blisters, making it relatively easy to diagnose. The characteristic is that the trunk areas such as the chest, back, and abdomen, as well as the head and face, can appear, with fewer limbs. Water blisters initially appear clear, like droplets of water, gradually becoming cloudy and then scabbing. "It usually takes two weeks to recover. In the first week, there will be repeated fever and occasional rash. The first characteristic of the rash is that it appears in batches, and the second characteristic is that it will no longer appear in new rash or fever after about a week, and then gradually scab." Li Dong once said. "Adult patients generally have severe symptoms, and a single infection can basically provide lifelong immunity," Ms. Shang told China News Network. She never thought that at the age of 25, she would also get chickenpox. On the evening of November 10th, she felt dizzy, had a slight headache, had a low fever, and felt drowsy. Later, she developed a pimple on her body, but at that time, she did not pay attention. Until the 12th, chickenpox began to appear densely, and she quickly went to the hospital to prescribe medication. This is my first time getting infected, I don't even know how to get it. Fourth
