Chikungunya to infest the Americas

AI Thread Summary
Research published in the Journal of Virology highlights the potential for a chikungunya virus epidemic in the Americas, particularly due to the influx of visitors for the FIFA World Cup in Brazil. The study emphasizes that Brazil, which has the highest incidence of dengue, is at increased risk because the same mosquitoes, Aedes aegypti and Aedes albopictus, transmit both dengue and chikungunya. The discussion also touches on the historical presence of these viruses and their spread due to increased human population density and mobility. While some participants express skepticism about the focus on chikungunya, pointing to the rising concern over Zika virus, they acknowledge that all three viruses are transmitted by the same mosquito species. The conversation reflects on the implications of mosquito-borne diseases and human travel patterns in the context of public health.

A team of French and Brazilian researchers warn that chikungunya virus is poised to invade, and become epidemic in the Americas according to research published ahead of print in the Journal of Virology.

The risk of a "catastrophic" epidemic in the Americas is boosted by the FIFA World Cup, to be held in Brazil next month, what with people coming in from near and from far, says corresponding author Ricardo Lourenco-de-Oliveira of the Instituto Oswaldo Cruz in Rio de Janeiro, Brazil. Brazil annually reports the highest incidence of dengue, a virus that is transmitted by Aedes aegyptiand Aedes albopictus, the same mosquitoes that transmit chikungunya, he says.

Where the heck are all these originating from?
 
Physics news on Phys.org
Check the date on the article: It's from two years ago. They probably picked the wrong flavivirus, as Zika virus, not Dengue or chikungunya, is causing the most concern at present.

As far as I can find, they've been in the environment for centuries. They now spread because human population has increase in density and there is increase mobility, particularly intercontinental travel. Human activity may also have reduced populations of birds (other animals?) and insects (arachnids?) that feed on mosquitoes.

What you say is true and it sucks that it is that way with the news and media because despite all the commotion and talks, it is less lethal than Dengue and Chikungunya and symptoms are less aggressive on the host. It simply became famous because of what happens to pregnant woman's babies.

Source (symptoms) (I copied them from Astronuc's post): Zika vs Chikungunya vs Dengue

Putting the symptoms and effects of the viruses in a balance, Zika should be of little concern to not-pregnant people imo. Although that doesn't imply it should be ignored. In the end it is the same kind of mosquito that can transmit all of the 3 diseases. Which probably answers Wolram question:

From the same kind of mosquito.
 
mosanto. the company. notice how mosanto and mosquito sound similar? :wideeyed::nb)
i said. it. there. ugh oh. i am smartest person in the king of the world.

anyways. as a killing agent, a mosquito is probably the best weapon, it produces so many and it travels because a human will get the virus and travel/
meaning if you travel a lot like some people you can acquire many viruses via mosquito. if your blood is exceptional. they will love you in asia and west indies.
