The unpredictable climate in spring, with unpredictable warm and cold temperatures and windy conditions, can be used by bacteria and viruses and other pathogenic microorganisms to spread infectious diseases such as influenza, chicken pox and rubella. Recently, a patient in his 40s came to Professor Locke’s clinic with prodromal symptoms such as fever, headache, sore throat, general malaise and abdominal pain five days before the rash. He was treated locally as a cold only, and the red papular rash on the face and trunk appeared as shown in the picture. It is no coincidence that another young man in his 20s came to Prof. Locke’s clinic. His symptoms included a migraine in his right ear, followed by a dozen blisters in his ear canal and increased pain. Then later there was tinnitus and even a little bit of inaudible sound …… The male was admitted to the ENT department for 10 days and then came back to see Prof. Locke’s clinic. He complained of itching in and out of his ears, and he could not sleep at night. And from the surface, the blisters have crusted over. In the two cases mentioned above, the first one had a head and face rash and the second one was herpes zoster in the ear, both of which are caused by varicella-zoster virus. The virus, because of its neurophilic nature, can be latent in the neurons of the posterior root ganglion of the cremaster nerve for a long time after infection. When resistance is low or when there is exertion, infection, cold and fever, the virus can grow and multiply again and move along the nerve fibers to the skin, causing intense inflammation of the invaded nerves and skin and producing pain. Usually the older you are, the worse the nerve pain is. As spring returns, chickenpox also has a tendency to rise, especially in infants and young children, and may also occur if they are in close contact with herpes zoster patients, because both diseases are caused by varicella-zoster virus, which can be spread by patient droplets and is highly contagious, and can also be contaminated by direct contact with herpes-contaminated clothing and utensils. It is important to note that after getting chickenpox, you should do early isolation until all the rash is crusted over, and avoid scratching the blisters, otherwise chickenpox leaves more than just a small “comma” for the patient. The following misconceptions about chicken pox may exist and should be screened. The first misconception is that chickenpox patients are only contagious when they have a rash. In fact, patients often have fever, headache, sneezing and other symptoms of upper whistle infection before the rash, from a week before the rash to about a week after the rash is contagious. The second myth is that if you have had chicken pox before, you will never get it again? The body is generally immune for life after the occurrence of chicken pox or shingles, and it is indeed rare for adults to get infected again. The actual fact is that you will not be able to get a new one if you have a new one, but you will be able to get a new one if you are overtired, malnourished, have a malignant tumor, have leukemia, have diabetes, and have a decreased immunity from the use of glucocorticoids and immunosuppressants. 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. Myth 3: Adults have a strong resistance and do not need to go to the hospital if they have chicken pox? The truth is just the opposite. In general, adults with chickenpox fever, headache and other symptoms are more prominent, the symptoms of systemic toxicity is heavier, the number of rash is more, and more likely to appear pneumonia, encephalitis and other complications, if not effectively treated in a timely manner, and may even be secondary to 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.
