Introduction

Epstein-Barr virus (EBV) is also known as human herpesvirus 4. In general, symptoms following EBV infection may include fatigue, fever, sore throat, enlarged spleen, and swollen lymph nodes. If these symptoms occur, medical attention is recommended. In daily life, maintaining a light diet, drinking plenty of water, and getting adequate sleep can help prevent infection.

Human herpesvirus 4 refers to the Epstein-Barr virus (EBV). In general, symptoms following EBV infection may include fatigue, fever, sore throat, spleen enlargement, and swollen lymph nodes. If any of these symptoms occur, medical attention is recommended. Specific analysis is as follows:

1. Fatigue

EBV infection triggers activation of the immune system, including increased activity of T cells and B cells. The activation of the immune system and viral replication process consume the body's energy resources, leading to feelings of fatigue in patients.

2. Fever

Immune system activation is typically accompanied by an increase in body temperature. Fever is part of the immune response against viruses, as elevated temperatures can enhance immune system activity.

3. Sore Throat

EBV infection may cause inflammation of lymphoid tissues, including those in the throat area, potentially resulting in a sore throat.

4. Spleen Enlargement

EBV infection can lead to proliferation of lymphocytes in the body, including lymphoid tissue within the spleen, possibly causing spleen enlargement.

5. Swollen Lymph Nodes

EBV infection may activate the immune system, and lymph nodes are one of the primary sites of immune response, thus leading to swollen lymph nodes.

In daily life, maintaining a light diet, drinking plenty of water, and ensuring adequate sleep can help prevent infection.

Can children with infantile roseola eat eggs?

During roseola in infants, eggs can be consumed in moderation as long as the child has no prior egg allergy and the eggs are thoroughly cooked. This illness is caused by human herpesvirus 6 or 7, most commonly affecting children between 6 months and 2 years of age. The typical course involves a sudden high fever lasting 3 to 5 days, followed by the appearance of a generalized rose-colored rash after the fever subsides. During the febrile phase, gastrointestinal motility slows and digestive enzyme activity decreases, so the diet should balance nutrition with easy digestibility.

Does infantile roseola recur?

Most cases of infantile exanthema are caused by infection with human herpesvirus 6 (HHV-6), while a minority are caused by HHV-7. After infection, the child's immune system produces specific antibodies that remain in the body long-term. When encountering the same type of virus again, these antibodies can quickly take effect and fight the infection, making recurrent disease extremely rare.
