World Health Organization Approves 15-Minute
Ebola Detection Test
By Lydia Ramsey
Today, the World Health Organization gave the green light to doctors in West
Africa to use the first ever rapid test for diagnosing the Ebola vírus. Until now,
the standard way to check for Ebola in the region was to use the nucleic acid
test, which works by identifying the genetic materiais of the vírus from a blood
sample. Yet the test requires a full lab to succeed, and it takes between 12 to
24 hours to process the results. ln comparison, the ReEBOV Antigen Rapid
Test gets the job done in 15 minutes by testing a patient’s blood for Ebola’s
antigen protein, which is distinguishable from other healthy proteins found in
the body. The rapid test isn’t as precise as the full lab test, but it can still identify
92 percent of people infected with Ebola and 85 percent of those without the
infection. This way, the quick test can easily identify who should at least enter
quarantine, thus putting a damper on potential flare-ups. However, WHO does
recommend following up the rapid test with a regular one to better assess if
a patient has the infection. As the epidemie dissipates, being able to clearly
distinguish Ebola from other diseases with similar symptoms will be key. Over
the next few years, animais may reintroduce the virus to humans, and it will
be important for health care providers to quickly identify which diseases they
are dealing with: Is it a routine case of malaria, or Ebola? With this test, they’II
have a good idea before things get worse.

Sobre o ReEBOV Antigen Test, é CORRETO afirmar que
A)
faz um diagnóstico tão preciso quanto outros testes usados.
B)
requer um laboratório equipado e profissionais especializados.
C)
identifica os infectados que deveriam entrar em quarentena.
D)
não distingue o vírus do Ebola de outras doenças.
Gabarito: C
Resolução:
O novo teste de detecção do Ebola identifica os infectados que deveriam entrar em quarentena. “this way the quick test can easily identify who should at least enter quarantine.”
