1. Symptom-free Incubatory Stage
Most people assume that measles starts when rashes start to appear. However, medical experts recognize that the condition has an initial incubatory stage with no obvious signs or symptoms. Measles actually starts the moment the patient catches the virus. The incubatory stage can last for up to two weeks without showing any visible indications.
Even though the patient will remain asymptomatic during the incubation phase, this stage is considered relevant. And whoever gets into contact with the patient during this phase will be at high risk of getting infected.
