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.

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.

CD4 T cells are not to be blamed for pushing dengue fever from bad to worse

No one knows what makes a mild dengue viral infection morph into a severe and sometimes deadly dengue hemorrhagic fever/dengue shock syndrome.

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.

Investigational vaccine protects macaques against four types of hemorrhagic fever viruses

Scientists funded by the National Institutes of Health have developed an investigational vaccine that protected cynomolgus macaques against four types of hemorrhagic fever viruses endemic to overlapping regions in Africa.

Vaccine for Lassa fever set to enter clinical testing in humans

There is currently no vaccine for the Lassa arenavirus, which causes Lassa fever. This hemorrhagic fever, endemic in West Africa, infects up to 300,000 people each year.

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.

Second round of Ebola vaccination trials on the way to DRC

A second experimental Ebola vaccine made by Johnson & Johnson will soon undergo clinical trials in the Ebola affected Democratic Republic of the Congo (DRC) announced health officials. The second round of vaccinations is to begin middle of October this year.

Researchers analyze people’s initial immune response to dengue fever

Researchers have come one step closer to understanding how our immune system responds to acute dengue fever, a disease that has affected hundreds of thousands of people in Southeast Asia this summer alone.

Promising new strategy to treat severe dengue disease on the horizon

Researchers led by Duke-NUS Medical School have discovered that tryptase, an enzyme in human cells that acts like scissors to cut up nearby proteins, is responsible for blood vessel leakage in severe dengue hemorrhagic fever.

Studying human behavior might help curb mosquito-borne illness

Control and prevention of Aedes-transmitted viruses, such as dengue, chikungunya, or Zika relies heavily on vector control approaches. Given the effort and cost involved in implementation of vector control, targeting of control measures is highly desirable. However, it is unclear to what extent the effectiveness of highly focal and reactive control measures depends on the commuting and movement patterns of humans.
