Chickenpox second time - this is an exception to the rule. Usually, the infection occurs only once in a lifetime. But despite the high prevalence of the disease, particularly the formation of the immunity to it, as well as the other herpetic infections, are not fully understood.
Chickenpox - especially childhood infection
Chickenpox - an acute viral infection characterized by a moderate violation of general condition of the body, as well as the emergence of bubble rash on the skin and mucous membranes. Chickenpox is caused by the herpes virus type 3
Herpes type 3 - causes chicken pox and shingles
- Varicella zoster. In young children, in most cases of chickenpox is mild, but in adolescents and adults - hard. Therefore, before it was thought that the child should recover as early as possible the infection, due to which some parents send their children to special source of infection.
In recent decades, it was clearly established that young children chickenpox often runs hard, with complications. Therefore, in the 70-ies of the last century there were a vaccine against chickenpox. The vaccine can prevent the development of infection or reduce the risk of severe its course.
It was also found that chicken pox is more severe in children and adults with impaired immunity. All the symptoms of the disease in these patients more pronounced: the incubation period is shorter, higher body temperatures, rashes spread more rapidly and quickly, the number of waves rash more elements of the rash more pronounced and are often formed on the palms of hands and soles of the feet, the healing of the rash proceeds longer, often joins secondary bacterial infection. Significantly increases the risk of death of the patient.
It is believed that the immunity after chickenpox transferred retained all his life, except for recurrent disease. But such a situation is typical for children and adults with normally functioning immune system.
One of the signs of our time is immunodeficiency caused by a variety of reasons, so today there are more reported cases of repeated occurrence of chickenpox parties, had already undergone this infection. Very often repeated chickenpox occurs in cancer patients - immunity they disturbed both by the underlying disease, and as a result of treatment - chemotherapy and radiotherapy.
Can I have had chickenpox twice?
A feature of chickenpox is that after undergoing pathogen infection it is not removed from the body and remains there in a dormant state, hiding in nerve cells. With the weakening of immune disease manifests itself in the form of local (in the course of the nerve branches) rash, similar to the rash of chickenpox. When sharply weakened immunity may cause a characteristic rash all over the body, ie chickenpox. In this case, there is no re-infection infection and activation of infection, which remains in the body after a person has had chickenpox the first time.
With a sharp decrease in immunity, and weakening of the body is very rare chickenpox a second time can be observed as a result of re-infection, which is obviously due to the violation of the formation of specific antibodies (immunoglobulins). Some experts have questioned the possibility of re-infection of chickenpox.
Finally, the "re windmill" may be due to diagnostic error. Despite the fact that this infection is very characteristic bubbly rash, it is sometimes confused with some other viral diseases, including herpes and enterovirus infections.
Currently it identified eight types of herpes viruses, many of which cause infection accompanied by various kinds of rash. Especially it seems can flow infection caused by herpes simplex virus
Herpes simplex - in fact, not so simple
1 and 2 diabetes. The herpes virus type 6
Herpes type 6 - causes different diseases
can cause disease in young children, accompanied by fever and a rash, which sometimes takes the form of small bubbles.
When enteroviral infections of the skin of patients often appear different kinds of rashes, including bubble. Sometimes this kind of bubble rash mistaken for chickenpox, noting that the patient developed chicken pox again.
Re chickenpox in children
Chickenpox in children - a mild infection, but there are exceptions
often it develops when the child is ill with this infection in grudnichkovom age when he has not yet formed immunity.
So is it possible to get sick with chickenpox again? Most experts believe that it is still possible, but very rare. In each case, re-disease chickenpox should understand individually, including the use of laboratory diagnostic techniques.
