In
the wake of ‘Zika’ virus creating havoc in Latin American countries, World Health Organization (WHO) declares Zika as global emergency. This gesture
reflects the seriousness of the situation as Brazil is worst hit by the
disease, as there are already 4000 registered cases by the end of 2015.
Zika was first appeared in Brazil by May 2015
and the virus quickly spread to as many as 20 countries within Americas. This
virus is basically affecting pregnant women, resulting abnormal child birth.
Children born of mother affected due to ‘Zika’ are born with abnormally small
heads with damaged brains. Doctors are of the view that this is a clear
evidence of ‘Microcephaly’ a congenital disease associated with abnormally
small head, with signs of incomplete brain development. Researchers are not
able to crack the mysterious link of the the Zika virus with that of Microcephaly
till date.
Causes
and consequences:
The
initial understanding about the spread of this killer virus was through Aedes mosquito bites, which acts as carriers of ‘Zika’ virus. Most of the ‘Zika’
affected do not show any symptoms and the minor symptoms if any can be seen in
the form of mild fever, headache, joint pains, eyes turning red, and rashes for
a week.
Zika
virus remains active for a week in the blood and it spread from person to
person through blood transmission, and sex.
Although
the disease appeared during 1947 in Uganda, scientists could successfully
prevent its spread for decades. Brazil firmly believes 2014 World Cup
Tournaments as the root cause of this disease, as foot ball fans in tens and
thousands have visited this country from across the globe.
Important
Measures to prevent Zika
Although
there is no clear vaccine to prevent this epidemic, the spread of the disease
can be prevented by taking necessary measures including safe sexual practices,
use of condoms, taking all necessary measures in case of blood transfusions
during emergency and measures that can stop the breed of mosquitoes freely. Pregnant
women must particularly stay very careful and should not visit the affected
countries.
Although
Bharat Biotech Ltd, a Hyderabad based Indian company declared that it has got
the breakthrough in the form of earliest vaccine to prevent this disease, it is
still at the nascent stage of trials and it may take 2 years or more to be
available for the general consumption.
