Measles

Explanation :

• Measles, also known as morbilli, rubeola, red measles, and English measles is a highly contagious infectious disease caused by measles virus.
• Measles morbillivirus, formerly called measles virus (MeV), is a single-stranded, negative-sense, enveloped, non-segmented RNA virus of the genus Morbillivirus within the family Paramyxoviridae.
• Humans are the natural hosts of the virus; no animal reservoirs are known to exist.
• Measles is an airborne disease which spreads easily through the coughs and sneezes of infected people.
• It may also be spread through direct contact with mouth or nasal secretions.

Symptoms

• The first sign of measles is usually a high fever, which begins about 10 to 12 days after exposure to the virus, and lasts 4 to 7 days.
• A runny nose, a cough, red and watery eyes, and small white spots inside the cheeks can develop in the initial stage.
• Koplik's spots seen inside the mouth are diagnostic for measles, but are temporary and therefore rarely seen.
• These are small white spots that are commonly seen on the inside of the cheeks opposite the molars.
