Can hantavirus infection spread among humans?

In connection with last year's epidemic, a research team at Umeå University in Sweden has managed for the first time to show that hantavirus exists in human saliva. This raises the question of whether this contagion can spread among humans.

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.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
