Why Do Blisters Appear on the Body?

Herpes is a type of skin rash with localized, raised, and fluid-filled lesions. The walls of the blisters are usually thin and easily ruptured. They can appear singly, in clusters, or scattered over the skin or mucous membranes of the human body. Herpes simplex infections usually manifest as blisters at the intersection of skin and mucous membranes, such as the lips or genital area. There are many factors that can trigger the development of herpes. Let's explore the reasons for herpes and its characteristics.

The majority of herpes cases are caused by herpes virus infections, insect bites, or allergic reactions. Herpes viruses can be classified into herpes simplex virus and varicella-zoster virus. Herpes simplex infections often result in blisters that appear at the intersection of skin and mucous membranes, such as the lips and genital area. These blisters may cause mild pain and tend to recur frequently. Varicella-zoster virus infections can cause herpes that can spread throughout the body without any conscious symptoms. The herpes can appear on one side of the body and is characterized by pain, numbness, and radiating neuralgia. In addition to viruses, connective tissue diseases such as pemphigus and pemphigoid can also cause symptoms of herpes throughout the body, but these are unrelated to viruses and can be challenging to treat with poor prognosis. Insect bites typically manifest as papular changes accompanied by intense itching, while herpes caused by allergic reactions also present with intense itching. It is recommended to seek medical attention for diagnosis and early treatment if herpes is suspected.

Herpes is a type of skin rash characterized by localized, raised, fluid-filled lesions with thin and easily ruptured walls. They can appear singly, in clusters, or scattered over the skin and mucous membranes of the body. In a broader sense, herpes refers to diseases caused by viruses of the Herpesviridae family. Currently, eight viruses from the Herpesviridae family, including herpes simplex virus types 1 and 2, varicella-zoster virus, human cytomegalovirus, Epstein-Barr virus, and human herpesviruses 6, 7, and 8, are known to cause human diseases. These viruses are collectively referred to as human herpesviruses (HHV). HHV is a group of moderately sized, enveloped DNA viruses that can cause various human diseases and can persist latently in the body, with recurrent infections occurring under certain conditions. Clinically, common manifestations include chickenpox, herpes zoster, herpes simplex, and genital herpes. Herpes can affect multiple organs in the human body and can occur at any age.

1. Strengthen the body and improve resistance to diseases. Older adults should maintain appropriate outdoor activities or participate in sports to enhance their physical fitness and improve their ability to resist diseases.

2. Prevent infection. Infection is one of the causes that can trigger herpes. Elderly patients should prevent infections from various diseases, especially during autumn when the temperature changes frequently. They should adjust their clothing appropriately to avoid catching upper respiratory infections due to cold exposure. Additionally, inflammation in the mouth and nasal cavity should be actively treated.

3. Prevent trauma. Trauma can reduce the body's resistance to diseases and increase the risk of developing herpes. Therefore, elderly patients should take care to avoid trauma.

4. Avoid exposure to toxic substances. Try to avoid contact with chemicals and toxic drugs to prevent skin damage, maintain good health, and maintain bodily resistance.
