A few months after global efforts culminated in clipping the claws of
Ebola virus disease in Africa, the World Health Organization, WHO,
Friday night announced the presence of Zika virus strain on the
continent. In a message made available to Sunday Mirror, WHO informed
that Zika virus had been raging in Cape Verde, located in West Africa,
where Ebola virus disease had killed over 11,000 people and destroyed
health systems of Liberia, Sierra-Leone and Guinea that were mainly
affected, within two years.
WHO proclaimed that the strain of Zika in Cape Verde is the same as
the one circulating in the Americas, Asian and the Caribbean. Presence
of Zika virus in Africa validates earlier fears that the disease might
return to a region where it was first discovered in 1947 – Uganda.
The disease is caused by the Zika virus, which is spread to people
primarily through the bite of an infected Aedes species mosquito. Should
the disease spread in Africa, as it has done in other regions, the
continent may face huge crisis, given large population of mosquitoes,
among which are aedes species, Sunday Mirror observation revealed. Among
others, Zika virus transmission results in congenital malformations,
such as microcephaly, as well as Guillain-Barré syndrome.
This is the first time that the Zika strain responsible for the
outbreaks linked to neurological disorders and microcephaly has been
detected in Africa, the organization noted. According to the
organization, as of May 8 this year, there had been 7,557 suspected
cases of Zika in Cape Verde, while three cases of microcephaly had been
reported from the country with one case reported by the U.S. Centers for
Disease Control and Prevention (CDC), after being delivered in the
United States. WHO Regional Director for Africa, Dr Matshidiso Moeti,
was quoted in the release as saying the findings were of concern, as
according to him, it is further proof that the outbreak is spreading
beyond South America and is on the doorstep of Africa. He added that
WHO’s message would help countries on the continent re-evaluate their
level of risk and adapt, and increase their levels of preparedness
against the disease.
The organization appealed to countries on the continent to heighten
risk communication to pregnant women to raise awareness of complications
associated with the Asian type of Zika virus and promote protection
steps to avoid mosquito bites as well as sexual transmission. “In
addition, countries should increase their surveillance for Zika
transmission and congenital malformations, such as microcephaly, as well
as Guillain-BarrĂ© syndrome. “Activated since February 2016, WHO Zika
Virus Disease Incident Management System in Brazzaville and at
headquarters will continue to review existing risk assessments, increase
surveillance, and assess laboratory testing capacity and support
community engagement and risk communications in priority countries. “In
addition, WHO and its partners will support the countries in the African
region to step up preparedness efforts for early detection,
confirmation and management of potential complications related to Zika
infection.
The response will build on investments in strengthened systems made
in West Africa during the Ebola emergency,” the agency stressed. Before
2007, at least 14 cases of Zika had been documented, although other
cases were likely to have occurred and were not reported. Because the
symptoms of Zika are similar to those of many other diseases, many cases
may not have been recognized, according to the US Centre for Disease
Control and Prevention. The agency added: “In May 2015, the Pan American
Health Organization (PAHO) issued an alert regarding the first
confirmed Zika virus infection in Brazil.
On February 1, 2016, the World Health Organization (WHO) declared
Zika virus a Public Health Emergency of International Concern (PHEIC).
Local transmission has been reported in many other countries and
territories. Zika virus will likely continue to spread to new areas.”
