It has been reported that some patients have been misdiagnosed with Allergic Reaction, when in fact the correct diagnosis in their specific case was Measles.
Measles also known as rubeola is a highly contagious viral disease caused by morbillivirus. Symptoms of measles includes a high fever, tiredness, a barky cough, bloodshot eyes, runny nose, and a signature red spotty rash that begins at the head and spreads down. Due to the measles, mumps and rubella vaccine, measles is now a rare diagnosis. Therefore misdiagnosis is common for conditions such as dengue fever, chicken pox, rubella, hand-foot-and-mouth disease, parvovirus, scarlet fever, and meningococcal.
