Measles has a high fever, with obvious symptoms of cough and runny nose. There are often measles mucosal spots on the cheek mucosa before the rash appears. Rubella generally does not cause a high fever, rarely causes cough, and has swollen lymph nodes behind the ears and on the occipital region. Roseola infantum has a high fever, but the fever subsides on its own after 2-3 days. Scarlet fever initially causes chills and fever, a red, swollen and ulcerated throat, and a "bayberry"-like tongue.

What causes herpes virus?

1. The most common herpes in daily life is shingles, which is an acute herpes caused by chickenpox and herpes zoster viruses. The virus can enter the human body through respiratory tract infection, and hide in the dorsal root ganglia of the spinal nerves, and may also hide in some human nerve cells.

2. Many times, the herpes simplex virus among viral herpes can cause genital herpes, causing infections of the skin, mucous membranes and many other parts of the human body. This type of herpes is usually transmitted through sexual contact.

3. Among viral herpes, there is also a type of simple herpes, usually called fever blisters. This is also an infection caused by a virus. Symptoms can appear anywhere in the body, most commonly in the mouth and nearby areas, and also frequently on the hands and cheeks.
