NAIROBI, March 9 (Reuters) - Global warming is pushing northwards
diseases more commonly found in developing countries, posing a risk to
the financial and physical health of rich nations, the head of a
livestock herders' charity said.
Steve Sloan, chief executive of GALVmed, said on Friday insect-borne
diseases were increasingly moving north, such as the viral infection
bluetongue that has hit cattle and sheep in the Netherlands, Belgium,
France and Germany.
If Kenya's Rift Valley Fever also reached Europe, the impact would be
immense, he said.
"These 'African' diseases have become global issues because of climate
change," Sloan told Reuters in an interview.
"Following the bluetongue outbreak in Germany, some meat markets in the
country saw an annual drop of up to a third," he said. "Wait until
something like Rift Valley Fever arrives, that brings death with it as
well."
Bluetongue, which is not harmful to humans, has been present for several
years in Spain and Italy.
The disease, transmitted by midges, was first discovered in South Africa
and has been spreading north since the late 1990s. Experts say that is
due to global warming.
"There is a very real threat that diseases like River Valley Fever will
follow bluetongue into Europe," Brian Perry, senior scientist at the
International Livestock Research Institute, told Reuters. "Climate
change has a definite impact in the establishment of these diseases."
Within a month of bluetongue being detected in the southern Netherlands
last year, the number of Dutch farms affected by it had doubled to more
than 400, despite measures to stop the spread of the virus.
"These are economic diseases that should frighten the hell out of
Europe's meat business, not to mention the threat they pose to human
lives," Sloan said.
"Climate change is bringing them to Europe."
GALVmed aims to reduce poverty of livestock keepers in developing
countries by improving access to pharmaceuticals and vaccines.
