An interesting article by Peter Cunliffe-Jones of Africa Check entitled "The Focus of Misinformation Debates Shifts South" is available here: http://www.niemanlab.org/2018/12/the-focus-of-misinformation-debates-shi...
Cunliffe-Jones writes, "In September 2018, my organization Africa Check ran a workshop in Nigeria on health misinformation, attended by stakeholders from mainstream media to the minister of state for health to leaders of the Nigerian Media Association. The workshop heard of messages circulating on WhatsApp that go beyond the widespread anti-vaccine scares to messages urging parents whose children are suffering conjunctivitis to bathe their eyes in battery acid to “cure” the problem. Research on this issue is being conducted now and details will emerge in 2019, including when the world’s leading fact-checking organizations meet in Cape Town in June."
In case you don't know it, Africa Check (https://africacheck.org/) is dedicated to fact-checking politicians and others, with a strong health focus.
