For a given epidemic or pandemic, the average of its estimated death toll range is used for ranking. If the death toll averages of two or more epidemics or pandemics are equal, then the smaller the range, the higher the rank. For the historical records of major changes in the world population, see world population. [3]
Measles is quite uncommon in populations of highly vaccinated areas, yet when it does occur, it is more commonly seen in adults. [19] The development of the measles vaccine has been vital in reducing outbreaks. Without a measles vaccine, measles epidemics could happen every 2 to 5 years and last up to 3 to 4 months at a time.

A hypothetical measles timeline from exposure to illness. Measles arrived in Samoa in 1893, carried by a steamer from New Zealand. By the end of 1893, over 1,000 people, of a population of 34,500, had died from measles. [11] Measles is much more contagious than other infectious diseases such as polio, which only requires an 80% vaccination rate ...

Measles cases in the US from 1938 to 2019. Before the vaccine was available in the United States, the Centers for Disease Control and Prevention (CDC) estimated that about three to four million were infected each year, of which approx. 500,000 were reported, with 400 to 500 people dying and 48,000 being hospitalized as a result.
The 2019 measles outbreaks refer to a substantial global increase in the number of measles cases reported, relative to 2018. [1] As of April 2019, the number of measles cases reported worldwide represented a 300% increase from the number of cases seen in the previous year, constituting over 110,000 measles cases reported in the first three months of 2019.
Cases of measles rose from 56 in 1998 to 1370 in 2008, and similar increases occurred throughout Europe. [153] In April 2013, an epidemic of measles in Wales in the UK broke out, which mainly affected teenagers who had not been vaccinated. [154] Despite this controversy, measles has been eliminated from Finland, Sweden and Cuba. [155]
Measles outbreaks have been on the rise in the United States, especially in communities with lower rates of vaccination. [123] A different vaccine distribution within a single territory by age or social class may define different general perceptions of vaccination efficacy. [ 193 ]
