Global emergency may be declared as yellow fever outbreak in South Africa. 293 people were dead as per WHO's reports.

Yellow Fever Outbreak In Southwest Africa

Johannesburg: Yellow fever outbreak in southwest Africa and could spread if not quickly contained. Medical experts are studying on this case whether to declare an international health emergency.

Though the panel convened by the World Health Organisation (WHO) may not make the declaration; a move had taken with Ebola and Zika outbreaks.The session will be held in Geneva on Thursday that speaks to the seriousness of the disease’s spread in Angola. Yellow fever infections tied to Angola already have been reported in China.

Faculty director of Georgetown University’s O’Neill Institute for National and Global Health Law,Lawrence Gostin, reported in an email that in his view, calling an emergency committee for yellow fever is clearly the right thing to do.There is the potential for rapid spread to other countries and regions, threatening the health of large populations in Africa, Asia and elsewhere, Gostin added. As the crisis escalates, global supplies of the yellow fever vaccine are dwindling and we could easily face a critical shortage. What this new emergency committee demonstrates is that mosquito-borne diseases — Zika and now yellow fever pose major threats. This requires a war against mosquito vectors with resources and a full range of technologies, as well as health education he made it clear.

Yellow fever is transmitted by Aedes aegypti mosquitoes, which also carry the virus Zika,which can cause severe birth defects that have swept South America in recent months.

The symptoms of yellow fever include high temperatures, jaundice, bleeding and eventually shock and failure of multiple organs. Between 20 per cent and 50 per cent of those who become jaundiced, entering what is known as the “yellow” phase of the disease, die from the virus, WHO officials said.

Gostin and his colleague Daniel Lucey, an immunologist at the O’Neill Institute in a paper published this month in the Journal of the American Medical Association, asked WHO to urgently convene an emergency committee to coordinate an international response, mobilise funds, and spearhead a surge in vaccine production to meet this emergency situation.The disease emerged last December in Angola, which had not had an outbreak in almost 30 years. Since then,as per the statistics provided by WHO 2,267 suspected infections have been reported and 293 people have died from the virus.There is also a situation where the disease has been imported by travellers from Angola to Kenya, China and the Democratic Republic of Congo, raising the alarm in other nations, including Namibia and Zambia that share a long border with Angola.The disease now spreads to other parts of the World.

WHO’s director of the pandemic and epidemic diseases department,Sylvie Briand told reporters at a briefing in Geneva last week that the risks for other countries really depend on how fast the cases are detected and the density of mosquitoes.We are concerned for other countries that may have high density of mosquitoes he added.

The outbreak in Angola is particularly worrisome because it is happening in urban areas such as the capital city Luanda, where the first cases in the country were detected, health officials said.Briand said that the there are trillions of mosquitoes and millions of people, so the capacity of transmission of the virus is multiplied enormously.The virus is far easier to fight in sparsely populated rural areas, she added.There is a situation for widespread of the disease as the vectors are enormously huge.

There is no treatment for yellow fever adds complication to the situation. The vaccination used to prevent the disease is highly effective. But the global supply of the vaccine is limited, according to information published WHO. The agency said that because of the current outbreak, shipments of the vaccine that would ordinarily be used in routine immunisation programmes in other countries where yellow fever is endemic were being used in Angola and other affected countries.

Ray Arthur, director of the Global Disease Detection Operations Centre at the Centres for Disease Control and Prevention (CDC), said in emailed comments that there had been no local transmission of yellow fever in the US since the early 1900s. And while many areas in the country have mosquitoes that can become infected and transmit yellow fever virus, the agency was not expecting local transmission of yellow fever in the continental United States,Arthur reported.

However, the CDC is concerned about travellers going to Africa and South America, where yellow fever is endemic, Arthur added and there can be a situation where travellers can return to the United States with a yellow fever virus infection.The agency is advising travellers to countries with yellow fever to review the vaccine recommendations and requirements to determine their need for vaccinations.
