Causes of Kawasaki disease in infants

The cause of Kawasaki disease in infants is not yet clear, but it is generally believed to be related to infection, genetic susceptibility and immune response. Parents need to carefully observe the symptoms and choose to seek medical treatment in time.

Kawasaki disease is a disease that mainly occurs in infants and young children. It is a type of vasculitis that causes inflammation of small and medium-sized blood vessels throughout the body. Scientists have not yet discovered the specific cause of the disease, but speculate that it may be related to certain viral or bacterial infections, especially when the infant's immune system is not yet fully developed, it may be more susceptible to external pathogens. In addition, children with a family history of Kawasaki disease may have a slightly higher risk, so genetic factors are also considered a potential cause.

Kawasaki disease usually brings symptoms such as high fever, rash, conjunctival congestion, redness and swelling of the palms and soles, and chapped lips. These symptoms may last for a long time and may even be accompanied by the risk of coronary artery damage. Infants are also more likely to have "atypical" (incomplete symptoms) Kawasaki disease, which may increase the difficulty of diagnosis. Environmental factors such as seasonal changes and influenza may trigger an increase in related cases to a certain extent.

If parents find that their baby has a persistent high fever with obvious systemic symptoms, they should take their child to the hospital for a detailed examination as soon as possible. Usually, they can create a clean living environment for their children to reduce the chance of exposure to sources of infection such as influenza, and at the same time, they can properly match their diet to enhance immunity. If they suspect that there is a family genetic tendency, they need to pay more attention to possible abnormal manifestations and seek professional advice as soon as possible.
