Tulane researcher reports on origin of deadly fever outbreak

15.09.2006
Multiple genetic varients clue to source of Marburg hemorrhagic fever outbreak

Bats or other cave dwelling animals may have been responsible for the deadly 1998–2000 outbreak of Marburg hemorrhagic fever among gold miners in the Democratic Republic of the Congo, according to an article in the Aug. 31, 2006, issue of the New England Journal of Medicine.

Daniel G. Bausch, associate professor of Tropical Medicine at Tulane University School of Public Health and Tropical Medicine and an international team of researchers identified multiple genetic variants of the virus in the outbreak, meaning the fever may have been spread directly to humans by the host animals. Marburg hemorrhagic fever, a severe filovirus-caused disease related to Ebola, was first identified in European research facilities in 1967 after outbreaks traced to infected monkeys imported from Uganda. Only a few sporadic cases were reported until the 1998–2000 outbreak in the Democratic Republic of the Congo.

The team recorded a fatality rate of 83 percent for that outbreak. Young male miners comprised 52 percent of the cases, suggesting that exposure in underground mines was a factor in the spread of the disease. The discovery of multiple different genetic variants of the virus indicates that the two-year outbreak was fueled by repeated new introductions of the virus into humans from the primary reservoir, rather than simply a single introduction followed by person-to-person spread.

Bausch's study enhances our understanding of Marburg virus, which the Centers for Disease Control and Prevention list as a "select agent" that may potentially be used in bioterrorism. There is currently no approved treatment or vaccine for the disease.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
