TEXTO
Brazil has declared an end to its public health
emergency over the Zika virus, 18 months after a
surge in cases drew headlines around the world.
The mosquito-borne virus was not considered a
major health threat until the 2015 outbreak revealed
that Zika can lead to severe birth defects. One of
those defects, microcephaly, causes babies to be
born with skulls much smaller than expected.
Photos of babies with the defect spread panic
around the globe as the virus was reported in dozens
of countries. Many would-be travellers cancelled
their trips to Zika-infected places. The concern
spread even more widely when health officials said
it could also be transmitted through sexual contact
with an infected person.
The health scare came just as Brazil, the epicentre
of the outbreak, was preparing to host the 2016
Olympics, fuelling concerns the Games could help
spread the virus. One athlete, a Spanish wind surfer,
said she got Zika while training in Brazil ahead of the Games.
In response to the outbreak, Brazil launched a
mosquito-eradication campaign. The health ministry
said those efforts have helped to dramatically reduce
cases of Zika. Between January and mid-April, 95%
fewer cases were recorded than during the same
period last year. The incidence of microcephaly has
fallen as well.
The World Health Organization (WHO) lifted its own
international emergency in November, even while
saying the virus remained a threat.
“The end of the emergency doesn’t mean the end of
surveillance or assistance” to affected families, said
Adeilson Cavalcante, the secretary for health
surveillance at Brazil’s health ministry. “The health
ministry and other organisations involved in this area
will maintain a policy of fighting Zika, dengue and
chikungunya.”
All three diseases are carried by the Aedes aegypti
mosquito.
But the WHO has warned that Zika is “here to stay,”
even when cases of it fall off, and that fighting the
disease will be an ongoing battle.
