New from me, in @ConversationUK
"#Dengue in France: tropical diseases in Europe may not be that rare for much longer" theconversation.com/dengue-in-fran…

A bit like #scabies, we do have Neglected Tropical Diseases in Europe
#ntds #beatntds
(1/n)
Few dozen cases of local dengue transmission, more than has been observed before (bit of a theme for #infectiousdiseases in the recent past...)

An infected traveller would have returned to France, been bitten by a local mozzie, with onward transmission from biting new humans.
Seeing more mosquito-driven disease in Europe. Loads of #westnile virus in the lowlands in northern Italy, plus a few cases across other Euro countries
Here in the UK, not seeing that so far. But there are intrepid entomologists who go bug hunting in the marshes to see what they find, to try and pick up early warnings of anything new and nasty
But #climatechange, along with other factors like globalisation, are shifting where we see mosquitoes and their pathogens
(indeed, #malaria was common in Europe about 100 years ago)
We'll be seeing more of things like Dengue, plus #yellowfever (fortunately a vaccine against that one, nasty disease, high mortality rate of a few percent seen in outbreaks)
And Europe isn't likely to escape the March Of The Mosquitoes.

We must be prepared, because we probably aren't right now (heard that one before in relation to #infectiousdiseases?)

The UK #monkeypox outbreak is very interesting. A 🧵of some key points
- typically very limited human-to-human transmission, needs very close contact
- therefore, transmission is nothing like #COVID19
- to add to other #publichealth voices, very very low risks to wider general public
- if close contact, then public health teams will follow up
- monkeypox can be very nasty (case fatality rates upwards of 1%, albeit most outbreaks in areas where healthcare is v limited)
- UK has several specialist facilities for handling unusual tropical medicine cases. NHS is very good at this.
- Name is a bit misleading. First identified in monkeys, but small animals like rats/other rodents a more common host (typically in parts of West/Central Africa)

Quick summation of thoughts around JCVI. Broadly agree with the concerns 👇, but have other comments

I also agree with views that 12-15 years vaccination should have been implemented a lot earlier. So much evidence in favour, never been much against.
(1/n)
I think a lot of the concerns could have been resolved by clearer comms.
Though bear in mind the top-level comms comes from Dept of Health & Social Care. Including decisions around publishing minutes, and what to publish/redact.
Consensus statements trump individual comments, that could have happened here with JCVI.
Where individual comments are ambiguous (for whatever reason) that can (and has here) muddied the waters.
Among the things that could be made clearer…

SAGE have now put out a statement, highlighting that segmentation (trying to reach #herdimmunity by letting the virus rip through a population) is not a good idea.

This follows on from many other expert groups saying the same. And there has been suggestions that scientists are divided on this topic.
Individually and collectively, they/we're really not... here's a few more examples...
The WHO, who called the idea ‘scientifically problematic and unethical’.

Pleased to announce new #beatNTDs paper published, covering our 2019 study on #scabies and skin infections in #Ghana.
Published in Transactions @RSTMH, with equity in authorship - academic.oup.com/trstmh/advance…

#globalhealth (/1)
We trained healthcare staff on recognising scabies & other skin infections. Over 6-month period, study clinics recorded and reviewed 385 cases of skin infections. There were 45 diagnosed scabies cases (3rd most common skin infection, behind bacterial #dermatitis and #tinea) (/2)
We also assessed how far the patient travelled from home to clinic. There was a lot of ‘bypassing’ (i.e. they did not attend their nearest health centre, they travelled further than in theory they needed to) (/3)
