Hemorrhagic Fever News and Research

RSS

Viral hemorrhagic fevers (VHFs) refer to a group of illnesses that are caused by several distinct families of viruses. In general, the term "viral hemorrhagic fever" is used to describe a severe multisystem syndrome (multisystem in that multiple organ systems in the body are affected). Characteristically, the overall vascular system is damaged, and the body's ability to regulate itself is impaired. These symptoms are often accompanied by hemorrhage (bleeding); however, the bleeding is itself rarely life-threatening. While some types of hemorrhagic fever viruses can cause relatively mild illnesses, many of these viruses cause severe, life-threatening disease.

Hantavirus can also be transmitted by wild or domesticated rats

A group of researchers from Charité - Universitätsmedizin Berlin have confirmed Germany's first-ever case of animal-to-human transmission involving a specific species of virus known as the 'Seoul virus'.

Promising new antivirals target arboviruses and SARS-CoV-2: Nodosome inhibitors

A new study describes two promising small molecules that inhibit a host cell factor, called nucleotide binding oligomerization domain-containing protein 2 (NOD2), that inhibits the replication and spread of many arboviruses. This could lead to the development of broad-spectrum antivirals. The study's findings have been published on the preprint server bioRxiv*.

New review explores the role of antibodies and T-cells towards an effective COVID vaccine

More than 100 companies have rushed into vaccine development against COVID-19 as the U.S. government pushes for a vaccine rollout at "warp speed" -- possibly by the end of the year -- but the bar set for an effective, long-lasting vaccine is far too low and may prove dangerous, according to Marc Hellerstein of the University of California, Berkeley.

Is COVID-19 the dreaded ‘Disease X' scientists warned us about?

Back in February 2018, the World Health Organization (WHO) talked about a new virus that will emerge and wreak havoc across the globe. Disease X was the term used for this new unknown pathogen that might cause a future epidemic.

Research shows how Ebola virus interacts with human lipids

Robert Stahelin studies some of the world's deadliest viruses. Filoviruses, including Ebola virus and Marburg virus, cause viral hemorrhagic fever with high fatality rates.

Marburg virus detected in fruit bats of Sierra Leone

The Marburg virus is a close relative of the Ebola virus explain researchers. It may also lead to the deadly life threatening hemorrhagic disease in patients as seen with Ebola. Until now there have been no reported cases of Marburg infection in Sierra Leone say health officials. The detection in the bats however could signal the risk the local population might be at or getting infected.

Scientists detect Marburg virus in Sierra Leone fruit bats

Scientists have detected Marburg virus in fruit bats in Sierra Leone, marking the first time the deadly virus has been found in West Africa. Eleven Egyptian rousette fruit bats tested positive for active Marburg virus infection. Research teams caught the bats separately in three health districts.

Sterilizing mosquitoes may be the answer to curb Zika, Dengue, Chikungunya, WHO reports

A new technique that sterilizes male mosquito through radiation shows promise in fighting mosquito-borne illnesses, including Zika, dengue and chikungunya. Soon, health experts plan to test the technique as part of global health efforts to control these diseases.

Computer model predicts location of future Ebola virus outbreaks

The Ebola virus disease (EVD) is a deadly infection that is highly contagious. It has taken thousands of lives across history, with a number of outbreaks mostly happening in West Africa. In the worse outbreak, between 2014 and 2016, there had been 28,616 cases of EVD, 11,310 of whom had died in the continent. Overseas, there had been 36 cases and 15 deaths.

Kazan University researchers study the genetics of nephropathia epidemica

This particular inquiry pertains to CCR5 - a gene which has lately been on the focuses of research worldwide. In particular, CCR5 deletion was used in China to perform the first ever genetic editing on human embryos. It's also known that a CCR5-Δ32 mutation can make people immune to HIV.
