Early this morning, when I arrived at the clinic, a young woman came in with an acute febrile appearance, conjunctival congestion in both eyes, red papules and blisters all over the scalp, face and trunk, and small pustules at the top of some of the blisters. The patient said that the rash was a little itchy at the beginning, but later the rash slowly became more and more, and the scalp was covered with it, and the blisters on the pressure area were painful and uncomfortable when she slept at night. I carefully examined the patient and thought it was chicken pox, and continued to ask about her medical history. The patient told me that she was a kindergarten teacher, and that several children in her class had recently been infected with chicken pox. Now, it is the spring back to the earth, chickenpox cases also have a rising trend, especially infants and young children, such as contact with herpes zoster patients can also occur chickenpox, because both are caused by varicella zoster virus, through the patient droplet transmission, highly contagious, but also direct contact with herpes contaminated clothing, utensils and other infectious. The actual fact is that the people’s understanding of chicken pox may be the following misconceptions: Misconception 1: Chicken pox patients are only contagious when they have a rash. In fact, patients often have fever, headache, sneezing and other symptoms of upper respiratory tract infection before the rash, from a week before the rash to about a week after the rash is contagious. The first thing you need to do is to get a good idea of what you are doing. The actual fact is not, the general body after the occurrence of chickenpox will produce lifelong immunity, adults re-infection is indeed rare, but in malnutrition, malignant tumors, leukemia, diabetes and long-term use of immunosuppressants, glucocorticoids and other cases of the body’s immunity decline can not exclude the possibility of secondary infection. In addition, because the varicella zoster virus infection can be long-term latent in the ganglion, when the body resistance or fatigue, cold, the virus can replicate again, manifested as herpes zoster. The first thing you need to do is to get a good idea of what you are getting into. The fact is just the opposite, generally speaking, adults chicken pox high fever, headache and other symptoms are more prominent, the symptoms of systemic toxicity is heavier, the number of rashes more, and more likely to appear pneumonia, encephalitis and other complications, if not timely and effective treatment, and may even secondary sepsis and other life-threatening. Finally, remind everyone to be aware of prevention, as little as possible to public places where people gather, pay attention to ventilation at home, avoid contact with chickenpox patients, children over 1 year old who have not had chickenpox can go to the hospital to get vaccinated against chickenpox.
