Measles is an extremely contagious viral disease caused by the measles virus, a member of the Morbillivirus genus. 

The World Health Organization (WHO) states that measles primarily affects children. The virus first infects the respiratory tract before spreading throughout the body.

Symptoms typically appear 10 to 14 days after exposure and usually last 4 to 7 days. Common symptoms include:

<ul><li>High fever</li><li>Cough</li><li>Runny nose</li><li>Rash covering the body</li></ul>

The WHO has maintained that vaccination is the most effective way to prevent measles and notes that disruptions caused by the COVID-19 pandemic led to setbacks in measles surveillance and immunization programs worldwide.

Vaccination rates have also been affected by growing vaccine hesitancy, with anti-vaccination groups discouraging <span>MMR vaccination</span>.

According to the WHO, measles vaccination alone has accounted for more than 60% of all childhood lives saved by vaccines worldwide over the past 50 years. 

One dose of the <span>MMR</span> vaccine provides about 95% protection against measles. A second dose, usually given between 4 and 6 years of age, increases protection to about 99%.

The second dose also provides 99% protection against rubella and 88% protection against mumps, making the two-dose schedule the global standard.
