Reservoir of Deadly Marburg Virus Detected in West Africa – Axios

Researchers chasing after the sources of fatal haemorrhagic fever, such as Ebola and Marburg, have made the first discovery of a Marburg reservoir in West Africa, Centers for Disease Control and Prevention, announced Thursday. Why the Question: After the fatal West African outbreak of the Ebola virus 2014-2016, researchers have sought more information about how animals, as the Egyptian fruitflies in Sierra Leone now carry Marburg, transmit the disease to humans. This discovery in West Africa means that there is a greater risk of human infection. Zoonotic viruses can jump from animals to humans . The animals are carriers of the disease but do not suffer from the effects of the infection. As human populations grow and settlements expand to new, once-forested countries, it is expected that people will encounter more zoonotic diseases in the coming decades. Background: In the wake of the Ebola eruption 2014-2016, two groups of researchers were searching for hemorrhagic disease services in West Africa. A member of the CDC and Njala University, and another by UC Davis and the University of Makeni. What the CDC Team Found : 5 Egyptian Rose Fruit Flakes – which can transmit the virus to humans through their saliva, stools or urine tested positive for active marburg virus infection. The Bad News: These bats were captured separately in 3 health districts, which means the risk is over a wide area.

Researchers chasing after the sources of fatal haemorrhagic fever, such as Ebola and Marburg, have made the first discovery of a Marburg reservoir in West Africa, Centers for Disease Control and Prevention, announced Thursday.

Why the Question: After the fatal West African outbreak of the Ebola virus 2014-2016, researchers have sought more information about how animals, as the Egyptian fruitflies in Sierra Leone now carry Marburg, transmit the disease to humans. This discovery in West Africa means that there is a greater risk of human infection.

Zoonotic viruses can jump from animals to humans .

  • The animals are carriers of the disease but do not suffer from the effects of the infection.
  • As human populations grow and settlements expand to new, once-forested countries, it is expected that people will encounter more zoonotic diseases in the coming decades.

Background: In the wake of the Ebola eruption 2014-2016, two groups of researchers were searching for hemorrhagic disease services in West Africa. A member of the CDC and Njala University, and another by UC Davis and the University of Makeni.

What the CDC Team Found : 5 Egyptian Rose Fruit Flakes – which can transmit the virus to humans through their saliva, stools or urine tested positive for active marburg virus infection.

  • The Bad News: These bats were captured separately in 3 health districts, which means the risk is over a wide area.
  • The Half-Goddess News: No-one in Sierra Leone has contracted the fatal disease, although there are indications that the virus is not new to the area (due to several genetic strains).
  • “We have long known that rosary flakes bearing Marburg viruses in other parts of Africa also live in West Africa. So it’s not surprising that we would find the virus in bats there,” CDC ecologist and team leader Jonathan Towner said in a press release.

Hot Level: The Marburg virus is found in the same philovirus family as Ebola, and also causes fever, headache, nausea and vomiting. Its symptoms can continue to bleed and several organ failure.

  • The largest and most deadly eruption of the Marburg virus occurred in Angola in 2005 and killed 90% of the 252 people infected.
  • In a worrying discovery, researchers working in Sierra Leone discovered the Angolan tribe of the virus in some of the flags there.

But, but: The colonies of Egyptian fruitflies tend to be much larger in sub-Saharan Africa, where Marburg viruses have infected humans, with more than 100,000 animals per colony, said CDC. The colonies in West Africa are much smaller, which can mitigate some of the risk of people there.
