Measles is a highly contagious infectious disease caused by measles virus. Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than 40 °C (104 °F), cough, runny nose, and inflamed eyes. Measles is an airborne disease which spreads easily from one person to subsequent through the coughs and sneezes of infected people. Despite major advances in increasing coverage with measles and rubella vaccine, recent reports note that a lot of countries and regions aren't on track to succeed in Global Vaccine Action Plan targets. To achieve vaccination coverage and equity targets that leave nobody behind, and accelerate progress toward disease eradication and elimination goals, sustained and predictable investments are needed for the identified research and innovations priorities for the new decade. Antibiotics won't help against the measles virus, but they'll sometimes be prescribed if a further bacterial infection develops. A biopsy will confirm the presence of the rubeola virus. People who have already had measles are normally immune and that they are unlikely to urge it again. People who aren't immune should consider the measles vaccine. There has been concern about an alleged link between the MMR vaccine a risk of autism, but scientists have found no evidence of a link.
