Evidence suggests that parasites may influence the immune system and lessen its response. They may help lower the levels of inflammation and reduce MS disease activity. A large group of parasites produce an array of molecules that influence immune response. The properties of these compounds may have therapeutic use that can help treat immune conditions, like MS.

Can parasites reduce the risk of MS? Some evidence suggests that parasites may help reduce the risk of developing MS. This theory suggests that infections offer a protective effect rather than inducing auto-immune conditions such as MS.

The environment plays a significant role in developing MS. Some research highlights that the prevalence of MS is lower in areas where parasitic infections are more common. This suggests that a reduction in parasite exposure, due to improved hygiene, may favor the development of MS.

As such, this supports that parasitic infections may play a protective role in MS. (Let them be dirty! 😘)
