Herpes zoster (shingles) is not directly contagious to family members. However, the varicella-zoster virus (VZV) present in the fluid of shingles blisters can spread to individuals who have never had chickenpox or received the chickenpox vaccine, potentially causing them to develop chickenpox. Therefore, it is advisable for individuals with shingles to avoid close contact with those who are susceptible until the blisters have crusted over.

Herpes zoster, also known as shingles, is an acute infectious skin disease caused by the varicella-zoster virus. Under normal circumstances, it can be transmitted to family members through direct or indirect contact. If any abnormalities occur, prompt medical attention is recommended. Detailed analysis is as follows:

There is a large amount of virus present in the blister fluid of herpes zoster patients. If the blisters rupture, direct contact with the broken skin or blister fluid may likely lead to virus transmission. The varicella-zoster virus can also spread indirectly through shared items such as towels, clothing, and toothbrushes. Family members who share these items with the patient may become infected.

In addition, the virus may enter the air when the patient exhales or sneezes. If family members stay in such a virus-containing environment for a prolonged period, they may become infected by inhaling the virus-containing droplets. Elderly individuals, children, or family members with chronic diseases and weakened immune systems are particularly susceptible to infection by the varicella-zoster virus.

Herpes zoster patients can use medications such as valacyclovir tablets, gabapentin capsules, and pregabalin capsules under a doctor's guidance. Both patients and their family members should maintain good personal hygiene habits, such as washing hands frequently, bathing regularly, and changing clothes and bed sheets periodically, to reduce the spread of the virus.
