Chikungunya poised to invade the Americas

08.04.2014

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 aegypti and Aedes albopictus, the same mosquitoes that transmit chikungunya, he says.

The basis of his worries is the study, in which he and his collaborators compared the ability of 35 populations of the two Aedes species to transmit three different genotypes of chikungunya. These populations ranged all over the Americas from Buenos Aires to Tyson, Missouri (near St. Louis.) Even in temperate Missouri, A. albopictus was found to have a high dissemination and transmission ability for two of the three chikungunya genotypes.

Chikungunya can cause severe joint pain, which can sometimes lead to permanent disability, according to the US Centers for Disease Control and Prevention. Mortality has been known to reach 1/1000. The virus' name reflects the condition of many of the stricken, "bent down or become contorted," in the Tanzanian Makonda language.

Transmission of chikungunya was first reported in the Americas in December of last year, on the Caribbean island of St. Martin. By February 5th, the disease had spread to nine additional Caribbean countries. "The danger of chikungunya virus spreading all over the tropical, subtropical, and even temperate regions of the Americas is a risk greater than ever," says Lourenco-de-Oliveira.

"Our results showed that the [Americas are] very receptive and vulnerable to CHIKV [chikungunya virus] transmission, and extremely exposed to the occurrence of an immediate chikungunya epidemic, since most regions are highly infested with both vectors."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
