An increase since its previous update, this number translates to someone, somewhere in the world, being newly diagnosed with the disease every five minutes, the National MS Society announced in a press release on the update.
A data-collecting study led by the Multiple Sclerosis International Federation (MSIF) and funded by the National MS Society, among others, the atlas provides up-to-date information about MS and its “global footprint.”
It was first published in 2008, and updated in 2013. For this newest update, the atlas’ epidemiology survey was completed by experts from 115 countries, representing 87% of the Earth’s population, between September 2019 and March 2020.
MS prevalence, data show, has increased in every world region — rising from an 2.3 million people affected in 2013 to 2.8 million in 2020.
“Since the last edition of the Atlas of MS in 2013, we have seen continued improvement in diagnostic guidelines and their global adoption is enabling many people with MS to be diagnosed earlier in the disease course. This is one of the factors contributing to our higher estimate of the total number of people living with MS,” Peer Baneke, CEO of the MS International Federation, wrote.
The 3rd edition also places the prevalence of pediatric MS, or disease diagnosed in people under age 18, at 30,000 worldwide.Based on atlas data, researchers can look for trends in who develops MS according to age, race, and geographical location. Such analyses may help to clarify what driving the increase seen in MS prevalence, and in identifying populations at highest risk.
Robust epidemiological data is also thought to be crucial in helping to inform decision making regarding policies and healthcare interventions for people with MS.
