In Sweden, a form of hemorrhagic fever with renal syndrome called nephropathia epidemica occurs primarily in the northern parts of the country. It is a zoonosis, that is, an infectious disease that is normally transmitted between animals and humans when a bank vole, for instance, releases Puumala hantavirus via its saliva, urine, and feces.
Normally humans become infected by breathing in dust polluted by virus from bank vole secretions or by direct contact with the animal.
It has recently been shown in South America that the Andes hantavirus, which is closely related to the Puumala hantavirus, can in some cases be transmitted among humans. The Umeå team's findings indicate that a possible path of contagion for hantavirus disease might be human saliva.
During last year's outbreak of nephropathia epidemica in northern Sweden, saliva samples were collected from 14 patients in Västerbotten County, and virus RNA was found in the saliva in ten cases. It is not clear whether the virus found in human saliva is capable of infecting another human, but this question is now being studied intensively.
Nephropathia epidemica, is a serious disease, and patients coming to hospitals often have high fevers, headaches, muscle pain, and abdominal pain, and are in generally poor condition. In Sweden some 2,200 cases of nephropathia epidemica were reported in 2007, and more than 800 of them were from Västerbotten County. Up to 30% of those who were diagnosed with nephropathia epidemica wind up in the hospital, and in Västerbotten County two deaths occurred in 2007. In South and North America infections by close relatives of the Puumala hantavirus lead to death in 40% of cases.
The Umeå team consists of Associate Professor Magnus Evander and resident specialist physician and doctoral candidate Lisa Pettersson at the Division for Virology and Assistant Professor Clas Ahlm and Post-Doctoral Fellow Jonas Klingström at the Division for Infectious Diseases, all at the Department of Clinical Microbiology, Umeå University. Other co-authors are Jonas Hardestam and Åke Lundkvist, Swedish Institute for Infectious Disease Control, Stockholm. The findings will soon be published in the journal Emerging Infectious Diseases.

On the way to developing a new active ingredient against chronic infections

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
