SARS Found in Tears

22.06.2004


SARS, the highly infectious respiratory virus, has been found in tears, reveals a small study in the British Journal of Ophthalmology.

The finding suggests that tear analysis could not only be an effective means of diagnosing the infection, but also an unrecognised source of its spread, if appropriate preventive measures are not taken, say the authors.

Tear samples were swabbed from the tear ducts of 36 patients in Singapore with suspected SARS over 12 days in April 2003. Most of those thought to have the infection were healthcare workers, including nurses.



Eight of these patients subsequently turned out to have probable SARS.

Chemical analysis confirmed the presence of the infection in three of these patients; in one, the virus was found only in the tears. These patients had only recently become infected - they were tested within 9 days of the start of symptoms.

The other five patients had no discernible evidence of the virus in their tear samples. But their symptoms had started over 11 days earlier, suggesting that the tear duct sampling may be a sensitive test for early stage infection, say the authors.

If the infection is caught early, this could make treatment (and isolation) more effective, they say. But the presence of the virus in tears poses a hazard for healthcare professionals caring for these patients.

It is not unusual for viral particles to be present in the eye, say the researchers. Herpes viruses, chicken pox, Epstein Barr virus, hepatitis C and B, and measles have all been detected in tears. But these are the first reported cases of SARS in tear duct fluid, they say.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
