Causes of Ripe Warts
- cause : Ripe warts are warts caused by an infection with unripe rice warts. which is a virus known as “MCV(Molluscum contagiosum virus – MCV*) This infection occurs only on the epidermis. Will not enter the body through the bloodstream or nervous system. The patient therefore had no symptoms of agitation, weakness or aches before. but will have the main symptoms Within after being infected by exposure This virus will divide in the epidermis cells. As more and more divisions, they clump together in the cytoplasm of the cell (Cytoplasm, the fluid inside the cell), called Molluscum bodies, which can be seen under a microscope. And when the doctor detects this lump through a biopsy of the skin that has the disease, it can help confirm the diagnosis.
- contact : This disease can be transmitted directly.from skin contact at the lesionfrom one person to another (But not everyone who touches it must be because it depends on the individual’s immunity and personal hygiene), from peeling or scratching the skin (from one skin to another in the same person, for example the first lesion is on the hand But when the finger that touched the disease to rub the eye It will cause the eyelids to stick to the rice warts as well), from having sex with a patient and can be attached fromSharing things with the patientwith lesions of rice warts such as handkerchiefs, towels, clothes, shoes, equipment in the gym including the use of a swimming pool with the patient (In young children, it is often transmitted from family members or from schoolmates.)

But it is especially found in children aged 1-10 years (in children, it is more common than adults. Because the immune system in children is not fully developed. In younger children, the immune system is transmitted from the mother. It is often not infected with this infection) and is often found in AIDS patients or people with low immunity. Because this group of people are more susceptible to virus infection than the general population. (The rate of rice warts is higher in AIDS patients, which is found in 5-18% of the AIDS population.)
- incubation period : From infection to onset of symptoms, it usually takes about 2-7 weeks.
note : There are four subtypes of MCV virus: MCV subtype 1, 2, 3, and 4. All four have the same symptoms and treatment methods, with MCV subtype 1 being the causative agent of the disease. most 98%
