We have updated estimates for the Mpox outbreak in Sierra Leone. We estimate that the G.1 lineage started to diversify in SL around 16 November, suggesting 1-2 months of circulation before detection. G.1's estimated growth corresponds to a doubling time of ~2 weeks: virological.org/t/genomic-ep...

The spread of Mpox in Sierra Leone is unlike anything we have ever seen - and we have been keeping an eye on this bug in the region for >15 years. Given geographical spread, 50/50 men vs women, this is no "sexual network". This could be the next one. clt.npha.gov.sl/outbreak.aspx

Well worth a read. Not because of the content - it's total horseshit - but because it's a prime example of what happens when you mix anti-science, conspiracism, arrogance, and a total lack of expertise.

Do you know what’s great about vaccines? We can stop outbreaks in the first place, so we don’t have to discuss half-witted hypotheticals about the precise circumstances we’d rather have kids exposed to a deadly, disabling virus…

RFK Jr: "It used to be that everybody got measles. And the measles gave you lifetime protection against measles infection. The vaccine doesn't do that ... it used to be that very young kids were protected by breast milk. Women who get vaccinated do not provide that level of immunity."

Frustrating to see science communicators posting videos about how a person with measles infects 18 others on average, without mentioning this is in a *fully unvaccinated* population. Measles can spread quickly in under vaccinated pockets of the population, but we don’t need to overstate risk. 1/
