Lassa Virus News and Research

RSS

Lassa virus or Lassa viral haemorrhagic fever is an acute illness of 1-4 weeks duration that occurs in West Africa. Though first described in the 1950s, the virus causing the disease was not identified until 1969. The virus is a single-stranded RNA virus belonging to the virus family Arenaviridae. Lassa fever is known to be endemic in Guinea (Conakry), Liberia, Sierra Leone and parts of Nigeria, but probably exists in other West African countries as well.

Lassa fever epidemic in Nigeria beginning to slow, but concern remains

After nearly 400 confirmed infections and 100 deaths, the spread of Lassa fever in Nigeria is beginning to slow but the epidemic is far from contained, the World Health Organization and the Nigeria Centre for Disease Control have warned.

Lassa fever strikes in Nigeria - high rates of fatality with no cure and no vaccine

Nigeria has been affected with an outbreak of the deadly Lassa fever since the start of this year. This disease typically has a high rate of fatality, no known cure and no vaccines have been developed against it yet. This is an unprecedented outbreak of this disease that is spreading faster than before. It is infecting more individuals than health workers can handle with their limited resources, say official sources.

New treatment protects nonhuman primates against Lassa fever eight days after infection

A collaborative team of scientists, led by a group at The University of Texas Medical Branch at Galveston, have successfully protected nonhuman primates against one of the most deadly viruses in the world, Lassa fever, eight days after they became infected.

Tulane University receives $12 million NIH grant to develop drug and vaccine against Lassa fever

The National Institutes of Health has awarded Tulane University more than $12 million to test a promising drug treatment against Lassa fever and develop a vaccine against the deadly disease endemic in parts of West Africa.

Researchers study Lassa fever patient's immune response and viral persistence

When an American nurse working in West Africa became ill with Lassa fever and was evacuated to the U.S. for treatment in 2016, it provided a rare opportunity.

TSRI study reveals first-ever structure of Lassa virus protein

Before Ebola virus ever struck West Africa, locals were already on the lookout for a deadly pathogen: Lassa virus. With thousands dying from Lassa every year - and the potential for the virus to cause even larger outbreaks- researchers are committed to designing a vaccine to stop it.

Researcher aims to eliminate chemotherapy-resistant ovarian tumors using virus treatment

In some cases, the Lassa virus starts with a fever and general weakness, moving toward headache, muscle pain, possible facial swelling, deafness, and worse. About 15 percent of patients hospitalized with severe cases die.

New model helps predict outbreaks of zoonotic diseases

A model that predicts outbreaks of zoonotic diseases -- those originating in livestock or wildlife such as Ebola and Zika -- based on changes in climate, population growth and land use has been developed by a UCL-led team of researchers.

TSRI study reveals important traits in LCMV, Lassa virus

For the first time, scientists at The Scripps Research Institute (TSRI) have solved the structure of the biological machinery used by a common virus to recognize and attack human host cells.

Investigational antiviral drug effectively treats Lassa virus infection in guinea pigs

Favipiravir, an investigational antiviral drug currently being tested in West Africa as a treatment for Ebola virus disease, effectively treated Lassa virus infection in guinea pigs, according to a new study from National Institutes of Health scientists and colleagues.

Antiviral agent protects rhesus monkeys from deadly Ebola virus

Rhesus monkeys were completely protected from the deadly Ebola virus when treated three days after infection with a compound that blocks the virus's ability to replicate. These encouraging preclinical results suggest the compound, known as GS-5734, should be further developed as a potential treatment, according to research findings to be presented tomorrow at the IDWeek conference.

TSRI study reveals ancient roots of Lassa virus and how it has changed over time

Working as part of an international team in North America and West Africa, a researcher at The Scripps Research Institute has published new findings showing the ancient roots of the deadly Lassa virus, a relative of Ebola virus, and how Lassa virus has changed over time.

Increase in Lassa fever cases could be due to human-to-human transmission, research reveals

One in five cases of Lassa fever - a disease that kills around 5,000 people a year in West Africa - could be due to human-to-human transmission, with a large proportion of these cases caused by 'super-spreaders', according to research published today in the journal PLOS Neglected Tropical Diseases.

New method could make Ebola surveillance quicker, cheaper for West African nations

A new method for examining the Ebola virus genome could make surveillance quicker and cheaper for West African nations, and help detect new forms of the virus. The detailed procedure is being shared with the research community along with the study paper, which is freely available in the open access journal Genome Biology.
