There is a child in the building, this year went to kindergarten, mother immediately felt the burden on her shoulders lightened a lot, happily dismissed the nanny. Don’t want to just go to half a month, the child out of chickenpox, rest at home for a week. Mother had to take annual leave to accompany her at home. This day met me in the corridor, complained:
[It’s just chicken pox. What a big deal, a few pox will be over. If you are afraid of infection, ask other children not to touch my son! I have to go home and isolate myself. Once again, you don’t have to worry any more. How nice! ]
A few short words revealed many misunderstandings of an ordinary mother about chickenpox. I didn’t know where to argue at the moment, so I had to ask vaguely, “Have you ever had chickenpox?” You have to take care of him and don’t get infected.]
She was surprised: [I am old, how can I still have chickenpox? ]
I think it’s time to tell you some truth about chickenpox.
Is chicken pox just a few pox? No.
Chickenpox occurs in children without underlying diseases (such as leukemia, HIV infection and other systemic diseases that cause low immunity), Fever is relatively mild, generally not more than 39 ℃, rash occurs within one day of fever, and pruritus is mild. Although rash can occur in batches, each batch starts to dry and scab in two or three days. Generally, the course of the disease will not exceed 2 weeks. As long as there is no scratching by itself, most of the scab will not leave scars after scab removal, and most of them are indeed self-limited.
Generally speaking, if you completely ignore it, it will be good for itself.
Therefore, in the eyes of many people, there is an illusion that chickenpox is not a big deal in what. Even when some parents take their children to the hospital, they will be laughed at by some three elder sisters and six elder aunts, saying that you are burning so much money that it is not good for their children not to be treated at all.
They don’t understand, In fact, chickenpox can also be severe, Both the number of rashes and the degree of fever will come differently from their children. In addition, Blister ulceration may lead to secondary skin infection. There are also some rare but real complications. Such as varicella pneumonia, encephalitis, hepatitis and thrombocytopenic purpura. Therefore, When the patient is too young, or any one of the abnormalities such as high fever, local suppuration infection, cough, headache and vomiting, it is still necessary to seek medical treatment in time. These are still aimed at ordinary people. If it really occurs in people with immune defects, such as leukemia and HIV infection, the mortality rate of infection has greatly increased and should be paid more attention to.
In particular, it is worth mentioning that chickenpox occurs in pregnant women during pregnancy and perinatal period, which may seriously endanger the fetus and newborn, and has certain risks of teratogenicity, resulting in serious systemic chickenpox infection of newborn and even death of newborn.
Afraid of infection, don’t touch chickenpox patients? Nor is it.
The virus that causes chickenpox is present in respiratory secretions, blister fluid and blood of patients. The main route of transmission is not direct contact with blister fluid, but through droplets. Various statistics show that nearly 60% of our children have chickenpox by the time they graduate from primary school and nearly 70% by the time they graduate from junior high school. We will be surprised to meet an adult who has not had chickenpox in our life.
Why do so many people have chicken pox? It is because the infectivity is very strong. From the day before the onset of the disease to the day when all skin lesions are scabbed, it is necessary to isolate them. Kindergarten advised this child to rest at home for a week. In fact, it is not harsh at all. It is not strict. If there is no isolation, other children may be infected just by talking close to each other for a while.
Have you ever had chickenpox and have you been safe ever since? Not exactly.
A child who has had chickenpox, even if the whole class has chickenpox, is unlikely to be infected again and suffer from chickenpox again. Because after infection, one can indeed obtain lifelong immunity and rarely suffer from secondary infection.
However, what the public does not know is that the full name of the pathogen of chickenpox is actually [varicella zoster virus), or VZV for short, which causes chickenpox and herpes zoster. In other words, although the child will not get chickenpox again, he may get herpes zoster in the future.
Varicella is the most common manifestation of human infection with VZV for the first time. A few are hidden infection. You think your fever has subsided, chickenpox has removed scabs, and your body has been completely cured. In fact, the virus has not gone at all. It ran to the epithelial sensory nerve endings of the skin, walked straight towards the road, walked to the neurons of the posterior root ganglion of the spinal cord, and stayed down. For a while, it did not say a word, nor did it make trouble, and lurked in the human body for a long time.
He is not a good master in what, he is a bully. In what, you were overworked, or happened to have pneumonia and gastroenteritis. What’s body was weak, or he was undergoing radiotherapy and chemotherapy for tumors, or even simply bullying you to be old. All these factors may make him run out again to dominate. This time it is manifested as herpes zoster.
Because VZV comes from the nerve in herpes zoster, the skin lesions are mostly a band distributed along the nerve direction with a group of herpes on it. It is also because it comes from the nerve. So it hurts. In elderly patients with herpes zoster, Residual neuralgia often persists after the skin blisters have completely subsided, A considerable part can last as long as half a year. The most common site of onset is intercostal nerve. Therefore, traditional Chinese medicine also calls this disease [Winding Waist Fire Pill]. In fact, it can also invade cervical nerve, trigeminal nerve, etc. When invading different nerves, There may be different complications. For example, when it invades the ocular branch of trigeminal nerve, it can form ulcerative keratitis, when it involves facial nerve and auditory nerve, it can cause tinnitus and deafness, and when it invades the central nervous system, it can also lead to meningoencephalitis.
Do adults still have chickenpox? Yes.
As mention earlier, Varicella is highly contagious, In the absence of vaccination, people are generally susceptible, So most people already have chickenpox before they reach adulthood, It won’t last that long, It makes people feel that chickenpox is a disease of children. This is a complete illusion. As long as you haven’t had it, Without vaccination, [Getting Older] This kind of thing won’t make you immune for no reason. Unfortunately, Adults suffer from chickenpox, and the symptoms are more severe than children’s: the fever is higher, the maintenance time is longer, the feeling is more tired and weak, and the blisters are more and more itchy. For example, the author, when he was 25 years old, received a child with chickenpox and developed chickenpox. From then on, I also accompanied VZV for a lifetime. It is really a regrettable story that the evening festival is not guaranteed.
