Mozzies bite one person and then go on to another and pass any diseases on. It's one of the ways that malaria is spread. African football supporters carried the disease across the Atlantic to Brazil so why can't African migrants carry the disease across the Med?

I would think that the most likely vector for the disease into Europe would be infected migrants from North Africa who would be bitten by local mosquitoes which would then transmit the disease on.


The question is whether the local species of Aedes can transmit the virus. This is unknown, because it is a temperate species of mosquito. The tropical and sub-tropical Aedes species already known to transmit the virus are not present in northern Europe.

Indeed. I guess we can't infer much from malaria as the process must be quite difference for a virus spread. Only certain mosquitos, in certain areas, transmit malaria as the malaria parasite needs quite a long time in the mosquito before it can be transmitted back to humans. Most species, and all species in cooler parts of the world simply don't live long enough.

I'd guess this time limitation wouldn't apply for virus transmission though?

Presumably not, but without research or other evidence, nobody knows.

Next African epidemic on the march, an oldie but still a killer (5% fatalities ?)


https://www.theguardian.com/global-development/2016/aug/16/fears-of-global-yellow-fever-epidemic-grow-as-vaccine-stocks-dwindle

The usual moskito vector, potential to go pandemic, limited vaccine stocks
because of 3 year shelf life.

And here is a real sign of the times.

I would put that one at the theoretical threat level.

Once administered the yellow fever vaccine lasts you for ten years so mine is about 35 years out of date now but many others will still be covered.

There will be plenty of politicians who will vote for BAU, despite information like this.

Ebola is still/again a threat and no longer safely consigned to yesterdays news.

It doesn't look like too much to worry about, though it could break loose again. Or mutate?

More likely than that is a new, uncontrollable animal.

Ebola is a disease that appears now and again. It is a hemorrhagic disease, and so can relatively easily be controlled with vitamin C. The disadvantage then is that vitamin C puts people at higher risk of malaria.

No free lunches.

However a vaccine will be useless in the long term unless hygiene and nutrition are improved, and then a vaccine wouldn't be needed (or safe).

Reports state that a significant Ebola outbreak has occurred in a remote region of the democratic republic of Congo.

Hopefully it will be contained.

Details available from the news media of your choice.

Useful occurance for the snake oil purveyors in the US.

Spreading at present: http://www.bbc.co.uk/news/world-africa-44150762

Congo has had numerous outbreaks in the past, so may be more experienced at dealing with it than the countries affected a few years ago, but the spread into an urban area is concerning.

However, there is an experimental vaccine to try this time, though not without difficulty due to poor infrastructure in Congo:
