'''Measles''' is a highly [[contagious]] viral [[disease]] that is easily treatable and has not typically been fatal for more than a half-century. There has been only one reported death in the U.S. from measles since 2003 (actually, from [[pneumonia]] induced by measles).<ref>https://www.forbes.com/sites/tarahaelle/2015/07/02/first-u-s-measles-death-in-more-than-a-decade/#55e36712a196</ref> 

[[Vitamin A]] is known to be effect in combatting and preventing harm from the measles.<ref>https://wwwnc.cdc.gov/travel/yellowbook/2024/infections-diseases/rubeola-measles#:~:text=Administer%20vitamin%20A%20as%20follows,a%20day%20for%202%20days.</ref>  Despite the known benefits of Vitamin A for the measles, health authorities often avoid mentioning it and instead urge the [[MMR vaccine]] - which can take three weeks to become effective.<ref>https://www.aol.com/news/cdc-dispatches-team-chicago-measles-220410412.html</ref> Some 4% of those vaccined by the MMR vaccine can still develop symptoms from the measles.

The [[Centers for Disease Control and Prevention]], with its bias for [[vaccination]] attributes most cases of measles in the U.S. to parents choosing not to vaccinate their children.<ref>https://www.cdc.gov/vaccines/pubs/pinkbook/meas.html</ref> In recent years, the number of measles cases in the U.S. has increased. According to the CDC, this is due to unvaccinated travelers contracting measles overseas and then spreading the virus when they return to the country.<ref>[https://www.npr.org/blogs/health/2011/05/24/136618682/u-s-measles-cases-hit-15-year-high?ps=sh_sthdl]</ref> In 2013, the CDC announced that measles outbreaks were increasing, but the total number of cases has remained very small compared with the overall population.<ref>[https://www.usatoday.com/story/news/nation/2013/12/05/measles-cdc-vaccine-vaccinations-disease/3878375/]</ref>

==Transmission==
Measles is very contagious, the virus is spread by respiratory droplets (when an infected person coughs, sneezes, etc). Measles virus can survive in the air and on surfaces for up to 2 hours, and 90% of non-immune people who are exposed to measles become infected.<ref>https://www.cdc.gov/vaccines/pubs/pinkbook/meas.html</ref>

==Symptoms==
A fever typically begins 10-12 days after exposure, the fever increases in stepwise fashion, often reaching 103-105 degrees F. Fever is followed by runny nose, pinkeye, and distinctive white spots inside the mouth ("Kopilk spots"). 1-7 days (usually 2-4)  after onset of fever, a rash appears at the hairline, this rash spreads over the body and then disappears in the order that it appears, lasting a total of 5-6 days. Peeling skin may occur on those body parts most affected by the rash. From 1985 to 1992 8% of measles cases in the US involved diarrhea, 7% resulted in ear infection, 6% resulted in pneumonia, 0.6-0.7% involved seizures, and 0.2% (1 in 500) were fatal (usually due to pneumonia or encephalitis), according to the CDC.<ref>https://www.cdc.gov/vaccines/pubs/pinkbook/meas.html</ref>

Acute encephalitis (brain inflammation) occurs in about 0.1% of measles cases (1 encephalitis case per 1,000 measles infections), and is fatal in 15% of cases, with up to 25% of survivors suffering permanent neurological damage. <ref>https://www.cdc.gov/vaccines/pubs/pinkbook/meas.html</ref>

==Prevention==
One dose of the MMR (measles, mumps and rubella) vaccine is at least 95-98% effective in creating immunity to measles.<ref>http://www.cochrane.org/CD004407/ARI_using-combined-vaccine-protection-children-against-measles-mumps-and-rubella</ref> Two doses are recommended by the CDC.<ref>https://www.cdc.gov/vaccines/schedules/hcp/imz/child-adolescent.html</ref> This is a live virus vaccine, and may cause some of the symptoms of measles, mumps, or rubella infections, such as fever, rash, and, in post pubescent females, temporary joint pain. Serious side effects listed by the WHO are as follows(1 in 10 means 1 case of the side effect per 10 doses of vaccine):<ref>http://www.who.int/vaccine_safety/initiative/tools/MMR_vaccine_rates_information_sheet.pdf</ref>

Acute arthritis (in teen girls and women): 1 in 10 

Febrile seizures: 1 in 2,000 to 3,000 

Thrombocytopenia (a blood clotting disorder): 1 in 30,000

Mumps virus meningitis: 1 in 100,000 to 1,000,000

Anaphylaxis (life-threatening allergic reaction): 1 in 285,000 to 1,000,000

Encephalomyelitis (autoimmune brain injury): 1 in 1,000,000

==Controversy==
Because it is the most contagious vaccine-preventable disease in the United States,{{cn}} measles is often cited as a justification for [[mandatory vaccination]]. However, measles is extremely rare in the US,<ref>https://www.cdc.gov/measles/cases-outbreaks.html</ref> despite the fact that 17 states allow parents to opt out of vaccinating their children for any reason.<ref>https://www.nvic.org/Vaccine-Laws/state-vaccine-requirements.aspx</ref> MMR vaccine has been the subject of controversy ever since a series of studies by [[Andrew Wakefield]] and others in the late 1990s raised suspicions that the vaccine may cause autism and bowl disease.<ref>https://www.historyofvaccines.org/content/articles/do-vaccines-cause-autism</ref> Since then, reviews of non industry funded studies(although some studies may have been funded by the federal government)<ref>https://articles.mercola.com/sites/articles/archive/2017/12/16/how-much-do-you-know-about-vaccine-safety.aspx</ref><ref>http://www.cochrane.org/about-us/our-funders-and-partners</ref> have not found evidence that MMR vaccine causes autism or bowle disease<ref>https://www.nap.edu/read/13164/chapter/6#144</ref><ref>http://www.cochrane.org/CD004407/ARI_using-combined-vaccine-protection-children-against-measles-mumps-and-rubella</ref>
