1. Is roseola infantum contagious?

Roseola infantum is an acute infectious disease caused by a virus and usually spread through saliva brought out of the respiratory tract. So it is contagious. If a child has close contact with a sick child and lacks immunity, it is entirely possible that he or she will be infected. Since the incubation period of roseola infantum is 1 to 2 weeks, you should closely observe your child during this period. If your child develops a high fever, you should immediately take measures to temporarily isolate him or her to avoid further infection.

Roseola infantum is a common exanthematous disease in infants and young children. Currently, most scholars believe that it is related to viruses.

This disease is mainly common in infants under one year old and can occur in any season. It is extremely rare for a person to be infected more than twice in his or her lifetime. Its clinical manifestations are acute onset, high fever reaching 39-40℃, which lasts for 3-5 days and then drops suddenly, with immediate improvement in spirits. Its characteristics are fever subsides and rash appears, or rash appears and fever subsides. The rash is mostly irregular, in the form of small rose spots, which may also merge into one piece and disappear with pressure. It first appears in the neck and trunk, and quickly spreads throughout the body, especially in the waist and buttocks. The rash disappears within 1-2 days without leaving any pigmentation. The disease may cause respiratory or digestive tract symptoms before the rash appears, such as pharyngitis and diarrhea. At the same time, the lymph nodes around the neck are generally enlarged, which is very meaningful for the diagnosis of roseola infantum.

There is no specific treatment for this disease, and antibiotics are ineffective. Only symptomatic treatment is needed. When you have a high fever, are irritable or easily startled, you can use antipyretic sedatives. If the high fever persists, you need to drink more fluids, such as boiled water, vegetable soup, fruit juice, etc.

Roseola infantum mostly occurs in infants and young children aged 6 to 18 months. The disease often develops suddenly, with a rapid rise in body temperature, usually between 39°C and 40°C. Severe patients with high fever in the early stages may have convulsions, and some may experience mild runny nose, cough, eyelid swelling, and conjunctivitis.

During the fever period, there are symptoms such as poor appetite, nausea, vomiting, mild diarrhea or constipation, as well as congestion in the pharynx and swollen lymph nodes in the neck. After three to five days of fever, the body temperature drops suddenly. After the fever subsides, the child may develop light red macules or maculopapules of varying sizes all over the body, starting from the chest and abdomen and quickly spreading to the whole body. At this time, the child's fever has subsided and he can fall asleep peacefully. This is medically called "fever rash", which is a unique manifestation of roseola infantum.

If the body temperature is high and the child is crying and irritable, physical cooling or a small amount of antipyretic drugs can be used to avoid convulsions. When a young mother encounters this situation, she should not rush to reduce her child's fever. Instead, she should check her child's vaccination status and cooperate with the doctor's treatment.
