- Two people in Ghana have died from the Marburg virus – and 98 been quarantined – raising fears of a mass outbreak.
- The highly infectious disease causes fever, muscle pains, diarrhoea, vomiting and, in some cases, death through extreme blood loss.
- Hundreds of people have died from the virus in the past, mostly in Africa.
A recent news article published in the BBC talks about Marburg virus and the ways to avoid it.
What is the Marburg virus?
A cousin of the equally deadly Ebola virus, according to the World Health Organization (WHO), the Marburg virus was first identified after 31 people were infected and seven died in simultaneous outbreaks in 1967 in:
- Marburg and Frankfurt, Germany
- Belgrade, Serbia
The outbreak was traced to African green monkeys imported from Uganda.
But the virus has since been linked to other animals.
Among humans, it is spread mostly by people who have spent long periods in caves and mines populated by bats.
This is Ghana’s first outbreak – but a number of African countries have had previously had cases, including:
- the Democratic Republic of the Congo
- South Africa
A 2005 outbreak in Angola killed more than 300 people.
But in Europe, only one person has died in the past 40 years – and one in the US, after returning from expeditions to caves in Uganda.
- 2017, Uganda: three cases, three deaths
- 2012, Uganda: 15 cases, four deaths
- 2005, Angola: 374 cases, 329 deaths
- 1998-2000, DR Congo: 154 cases, 128 deaths
- 1967, Germany: 29 cases, seven deaths
What illness does it cause?
The virus begins abruptly with:
- a fever
- severe headache
- muscle pains
This is often followed, three days later, by:
- watery diarrhoea
- stomach pain
The WHO says: “The appearance of patients at this phase has been described as showing ‘ghost-like’ drawn features, deep-set eyes, expressionless faces and extreme lethargy.”
Many people go on to bleed from various parts of the body, and die eight to nine days after first falling ill, because of extreme loss of blood and shock.
On average, the virus kills half those infected, says the WHO, but the most harmful strains have killed up to 88%.
How is it spread?
The Egyptian rousette fruit bat often harbours the virus.
African green monkeys and pigs can also carry it.
Among humans, it spreads through bodily fluids and contact with contaminated bedding.
Even after people have recovered, their blood or semen, for example, can infect others for many months afterwards.
How can it be treated?
There are no specific treatments or a vaccine for the virus.
But a range of blood products, drug and immune therapies are being developed, the WHO says.
How can it be contained?
People should also avoid contact with pigs in areas with an outbreak, says the WHO.
Men who have had the virus should use condoms for a year after the onset of symptoms or until their semen tests negative for the virus twice.
Those who bury people who have died from the virus should also avoid touching the body.
