Shingles is caused by the activation of the varicella-zoster virus that lies dormant in the nerve roots, affecting both the skin and nerves. There are several ways shingles can spread, mainly through direct contact or droplet transmission. Direct contact transmission primarily occurs because the blister fluid in shingles blisters contains a high concentration of the virus. Therefore, before the blisters of a person with shingles are completely dry, they are somewhat contagious, primarily affecting those with lower resistance such as the elderly, children, women of childbearing age, pregnant women, and so on.

What family does shingles belong to?

Shingles can be treated in three medical departments. First, dermatology. Since the blisters primarily appear on the skin, seeing a dermatologist can treat shingles. Second, neurology. As shingles may be caused by nerve damage, treatment can be sought from a neurologist. Third, for severe pain, especially if postherpetic neuralgia remains after shingles, one can consult the pain management department. The initial symptoms of shingles are mainly pain, particularly unilateral limb or unilateral scalp/facial pain.

How many days can herpes zoster be cured?

Herpes zoster is a viral infectious skin disease that is most prone to epidemic in the spring, primarily caused by the varicella-zoster virus. It generally lies dormant in the body causing a belt-like cluster of herpes zoster to appear along the dermatome, accompanied by neuralgia. The course of herpes zoster generally lasts three to four weeks, and it usually does not recur after recovery. The main principles of treatment are antiviral, analgesic, anti-inflammatory, to shorten the duration of the disease, and to prevent secondary infections.

Does shingles cause fever?

After contracting shingles, it is possible to experience symptoms of fever because this illness can lead to inflammatory responses. These inflammatory responses may manifest as systemic symptoms, such as fever. If fever occurs, it is advisable to use physical cooling methods or antipyretic medications for treatment, while concurrently addressing the primary illness of shingles. This involves using antiviral drugs and medications that nourish the nerves. It is also important to maintain a light diet, avoid spicy and irritating foods, and ensure plenty of rest.

How long does herpes zoster take to heal?

The healing time for shingles varies from person to person; generally, younger people recover faster, while older individuals take longer. Treatment typically includes oral antiviral medications like famciclovir and acyclovir, as well as nutrients for nerve health such as vitamins B1 and B12, along with oral traditional Chinese medicine and acupuncture. However, if it progresses to postherpetic neuralgia, the condition tends to heal more slowly. Postherpetic neuralgia can only alleviate pain but is generally difficult to cure completely.

How long will shingles take to heal?

The duration of recovery from herpes zoster varies from person to person and depends on the severity of the condition. If the herpes zoster only causes skin symptoms and does not lead to complications such as postherpetic neuralgia, then it is possible to recover with antiviral treatment within two weeks. However, if it causes other infections or complications like postherpetic neuralgia, then it may take months or even years to heal. Therefore, during the period of suffering from herpes zoster, it is essential to strengthen one's immunity, rest more, and engage in appropriate exercise.
