Poisonous algal blooms in coastal waters may increase as a result of warming temperatures or changes in littoral sea life. A newly emergent virus, carried by mosquitoes that causes fever and weakness, has spread quickly through Africa and the Middle East, killing people, along with camels, cattle, goats and sheep.
Global warming will change the distribution of the tsetse fly that carries the disease, now infecting more than , people yearly in Africa.
Victims become lethargic and may suffer severe swelling of the lymph nodes. Both the human and livestock varieties of TB are likely to increase, particularly the latter as droughts bring livestock and wildlife into closer proximity at watering holes.
Mosquitoes spread this disease, which causes fever and jaundicelike symptoms, between wildlife and humans, and will likely spread into new areas as the climate changes. To counter outbreaks, monitoring efforts for yellow fever in South American monkeys have already helped target health interventions and vaccinations.
And the Global Avian Influenza Network for Surveillance GAINS —an international effort to monitor bird flu in wild and domestic birds—has helped map how the disease spreads, and helped prevent a major outbreak in humans. Karesh and his colleagues argue that this bird flu network should be transformed into a broader effort that surveys all wildlife diseases.
As it stands, those risks are increasing as a result of human encroachment on remaining wild landscapes, mining and logging, and rapid global transport such as jet travel that promote the speedy spread of disease as does global trade in both livestock and wildlife.

Why Do Facts Fail? Deconstructing Denial Learn More. The best defense, according to the authors of these reports, is a good offense in the form of wildlife monitoring to detect how these diseases are spreading so that health professionals can learn and prepare to mitigate their impact.
Bird flu, cholera, Ebola, plague and tuberculosis are just a few of the diseases likely to spread and get worse as a result of climate change. DEADLY BY THE DOZEN - Kindle edition by Mark Terry, Natasha Fondren, Lise McClendon, Jude Hardin, Robert Weibezahl, Betsy Dornbusch, Erica Orloff.
