Allergic purpura is a relatively common disease, and the risk of children developing it is also relatively high. Therefore, pediatric allergic purpura is not a rare disease. However, many parents are not very familiar with allergic purpura and are concerned about its infectivity. So now let's take a look at whether pediatric allergic purpura can be contagious?
Allergic purpura is not contagious. To determine whether the disease is contagious or not, it mainly depends on the nature of the disease. Allergic purpura is actually a vasculitis disease in rheumatology and immunology, characterized by vasculitis like manifestations caused by immune disorders, and is completely different from infection and infectious diseases. Tuberculosis, hepatitis, and other infectious diseases are only contagious if they have sources and transmission routes. Allergic purpura is not originally related to the source of infection, and the pathogenic factors are not related to the pathogen, so allergic purpura is not contagious.
The cause of allergic purpura is not particularly clear, and the disease may have triggers such as mosquito bites. After being bitten by mosquitoes and insects, some children may show symptoms of allergic purpura a few days later, but there are also some children who may experience symptoms of the disease after being infected with tonsillitis or respiratory tract infections. Some children may experience symptoms of the disease after eating seafood, but the above may be triggering factors and not directly related to allergic purpura itself. So not all cases of allergic purpura require an allergy test to confirm that it is allergic purpura.
