Climate changes will increase evolution of new flu strains

with one comment

A report from Duke University’s Nicholas School of the Environment says changing climate will affect the likelihood of contracting a new deadly strain of the flu. Never mind the heat — it’s the infection that will get you.

Migratory birds play a central role by giving a virus an additional opportunity to evolve

It’s the shifts between El Nino and La Nina weather that will wreak havoc with the bird migration patterns. Birds, migratory birds in particular, play a central role, by either passing a flu strain directly to humans (as in the case of H1N1) or indirectly via an intermediate host, giving the virus an additional opportunity to evolve.

The El Niño-La Niña oscillations cause significant changes in regional rainfall rates and wind patterns, which in turn affect the migration pattern of birds. And these shifts lead to different groups of of bird species coming into contact with each other in a given region, allowing for new strains of influenza to develop that eventually jump to humans.

In Viral Times, birds are an active transmission agent in the spread of the New Flu and other viruses. The dominant breeds of birds, especially starlings and crows, are among the deadliest of these agents.

The El Niño-Southern Oscillation (ENSO) refers to the state of the tropical Pacific Ocean as it sloshes back and forth, like water in a huge bathtub, west and east between Asia and the Americas. This movement affects temperatures and weather patterns worldwide.

One means to combat the infection might be to reduce use of fossil fuels. But after generations of burning coal and oil, it might be too late to reverse the Nino-Nina bathtub slosh effects. It’s back to our firewall of protection against viruses: natural immunity.
