The difference between roseola infantum and measles
The differences between baby roseola and measles mainly include the following points: Firstly, the causative pathogens are different. Baby roseola is caused by the infection of human herpesvirus 6, whereas measles is caused by the measles virus. Secondly, the symptoms of fever differ. Typically, in baby roseola, a rash appears after 3-5 days of fever as the fever subsides; in measles, a rash appears after 3-4 days of fever, during which the temperature may actually increase. Thirdly, the prognosis differs. Baby roseola is a relatively common disease that generally heals gradually as the fever and rash subside. If measles is not treated, it may lead to severe symptoms and potentially leave some sequelae. Lastly, their treatments are also different.
