Watery vesicles on the skin and mucous membranes are caused by?
Watery vesicles on the skin and mucous membranes can be caused by viral infections such as herpes simplex virus (HSV), varicella-zoster virus (VZV) causing chickenpox or shingles, and coxsackievirus causing hand, foot, and mouth disease. These vesicles typically contain clear fluid and are often accompanied by itching or pain.
What is the connection between varicella and the chickenpox vaccine?
Varicella Zoster is a type of herpes virus that is commonly the cause of chickenpox. The chickenpox vaccine, often called the Varicella vaccine, is a live virus vaccine to protect against chickenpox, as it can be extremely dangerous in adults. As shingles can also result from the same virus, the vaccine protects against that as well.
Are ulcers in the mouth oral herpes?
No, mouth ulcers are not the same as oral herpes. Mouth ulcers, also known as canker sores, are small open sores that occur inside the mouth, while oral herpes is an infection caused by the herpes simplex virus, typically manifesting as cold sores on the lips or mouth.
What is Acyclovir?
Aciclovir is a medication used to treat the herpes virus infections. It also is used to treat chickenpox. It is not meant to cure these infections but to prevent a breakout of herpes or blisters.
Are canker sores a form of herpes?
No, canker sores are not a form of herpes. Canker sores are small, shallow ulcers that occur inside the mouth, while herpes is a viral infection caused by the herpes simplex virus which typically causes cold sores or genital herpes.
What is erythema multiforme, is it a disease?
Erythema multiforme is a skin disorder due to an allergic reaction or infection. The symptoms are fever, general ill feeling, itching of the skin, joint aches, and multiple skin lesions. If not treated it can be really serious, even fatal.
What are common circumstances for getting transverse myelitis?

Different anug and herpetic gingivostomatitis?
Angular cheilitis is a condition characterized by inflammation and cracking at the corners of the mouth, typically caused by a combination of factors including fungal or bacterial infections, nutritional deficiencies, and drooling. Herpetic gingivostomatitis is a viral infection caused by the herpes simplex virus, presenting as painful sores in the mouth and on the lips. Both conditions can be uncomfortable but are treated differently, with angular cheilitis often responding well to antifungal or antibacterial creams, while herpetic gingivostomatitis may require antiviral medication.
Herpes viral culture of lesion?
DefinitionHerpes viral culture of a lesion is a laboratory test to check if a skin sample is infected with the herpes simplex virus.See also:Genital herpesHerpes labialis(cold sores)Serum herpes simplex antibodiesAlternative NamesCulture - herpes simplex virus; Herpes simplex virus cultureHow the test is performedA sample from a skin lesion (often a genital sore) or blister is needed. The health care provider will collect the sample during an active outbreak and place it in a laboratory container. The sample must include cells, not just fluid from the blister, because the virus is in the skin cells of the blister or ulcer.At the laboratory, the sample is placed in a special dish and watched for the growth of the herpes simplex virus, or substances related to the virus. Special tests may also be done to determine whether it is herpex simplex virus type 1 or 2.Results are available within 16 hours to 7 days (usually 2-4 days), depending on the laboratory method used.How to prepare for the testThe sample must be collected during the worst part of an outbreak. This is considered the acute phase of infection.How the test will feelWhen the sample is collected, you may feel an uncomfortable scraping or sticky sensation. Sometimes a sample from the throat or eyes is needed. This involves rubbing a sterile swab against the eye or in the throat.Why the test is performedThe test is done to confirm herpes simplex infection. The diagnosis is often made by physical examination (the health care provider looking at the sores), and the cultures and other tests are used to confirm that diagnosis.Normal ValuesA normal (negative) result means that the herpes simplex virus did not grow in the laboratory dish and the skin sample used in the test did not contain any herpes virus.Unfortunately, a normal (negative) culture does not guarantee that you do not have a herpes infection or have not had one in the past.What abnormal results meanAn abnormal (positive) result may mean that you have an active infection with herpes simplex virus. Herpes infections include herpes genitalis, which is genital herpes, or cold sores on the lips or in the mouth.If the culture is positive for herpes, you may have recently become infected or you may have become infected in the past and are currently having an outbreak.What the risks areRisks include slight bleeding or infection in the area where the skin sample was removed.Special considerationsThe viral culture for herpes test is most likely to be accurate when a person is newly infected (during the first outbreak).ReferencesGupta R, Warren T, Wald A.
