The Measles outbreak in the USA is a surprise. In follow up from Part 1 Signs and Symptoms of Measles in Authentic Medicine, I have discussed the treatment needed for a patient with measles and exposure prophylaxis of others in close contact with someone with Measles. Please read in Authentic Medicine Part 2 for the treatment of Measles. As of April 26th, 2019 the USA had reached 704 confirmed cases of measles.
