Dr. Yong Prof. Dr. Yong Phuworawan Head of the center specializing in clinical virology Faculty of Medicine Chulalongkorn University stated through Facebook that “RSV” In Thai children, there is a high incidence of infection. It can be repeated again. open research data “RSV” of the center has been published in the journal International Journal of Infectious Disease It can be seen that immunity is passed on from the mother and declines rapidly within 6 months, after which a large number of infections occur in the first and subsequent years, in other words, at the age of 4. Almost everyone has been infected. “RSV” And some people have recurrent infections. or repeated almost every year.
This study was a long-term study. In children from birth to 4 years of age, an autoimmune test is performed. “RSV” seeing that the landscape from mother It will be sent to protect the baby in a relatively short period of time. And when the immune system is reduced or gone, the child will start to get infected. Therefore, it is not strange that the infection is often seen, whether small children andincrease after 6 months Infection this year and next year there may be another infection.
In general, infection in small children Symptoms are more severe in older children. and over the age of 3, the infection “RSV” Most of the symptoms are mild, and after 5 years of age, there is still an infection. even in adults will create another problem in the elderly or those with impaired immune systems, as well as respiratory disease other and the same as Covid19
Longitudinal study in the pediatric population It took more than 5 years to study and saw the information of Thai children clearly. especially the level of immunity detection and the detection of recurrence. The information obtained will be useful in the future if any. vaccine in defense It should be given before the first 6 months.
ongoing studies, see species of re-infected viruses found that although the virus is the same group RSV-A or RSV-B It can still be repeated. subspecies same as ON1 Once attached, it can be repeated again.
Details of the project study will continue to be published in international journals. The information made is very important as a new body of knowledge. especially in terms of bringing vaccines to use So it’s not easy. to prevent infection “RSV”
