Zika virus has created concerns among professionals in the Health care industry,
raising questions about the best way to tackle the recent public health emergency.
Initially discovered in
monkeys in 1947, the virus was first diagnosed in a human in Nigeria around 1954.
Since then, the virus has slowly been spreading to areas in
Africa, South East Asia, and the Pacific Islands. Although no locally
transmitted cases have been reported in the United States, there have been
cases reported amongst travelers
returning from countries where the virus is spreading. In 2016, from January 3rd to March 5th, more
than 4,500 people were tested for Zika, of which 182
virus spreads primarily through infected mosquitos and produces minor symptoms;
such as mild fevers, conjunctivitis, headaches, joint pains, and rashes. The
main reason health authorities are concerned, however, is because of the
link to birth defects, namely
is a defect in which a baby is born with a smaller than normal head, leading to
improper brain development. The fact that Zika is a cause of microcephaly, can
transmitted, and is found in individuals who have returned from areas where
the virus is spreading, are all reasons why health authorities in the U.S. are
taking safety measures to address the virus. One Such safety measure has been the FDA’s recommendation
that Zika infected individuals be deferred from donating blood.
FDA’s concern regarding blood transmission of Zika is premised on reports of transfusion
associated infections that have occurred outside the U.S., specifically
in Brazil, and the fact that many who are infected with Zika are not aware that they have
symptoms. Zika symptoms typically do not last for more than a week and those affected
typically do not visit the hospital because their condition does not worsen. The
chances of someone contracting Zika and being aware are low, which could
potentially affect the national blood supply if a Zika infected blood donor
transmits his or her blood to another already ill patient. Therefore, the FDA
that donors at risk of contracting the virus be deferred from donating blood
for four weeks. Those at risk include anyone who has had Zika-related symptoms,
sexual contact with someone who has traveled to or been in an area where the
virus is spreading in the past three months, or traveled to areas that have a
high transmission rate of Zika in the past four weeks.
addition, the FDA recommends that blood collection centers update
their donor history questionnaire to better determine which donors have a
history of living in or visiting Zika-infected areas. The FDA also provides
guidance for those blood centers that have collected blood, distributed it,
or know that it has been transfused. For blood centers that have collected
blood from a donor that may be at risk of having Zika, the FDA recommends the
center to quarantine and destroy all blood components collected. Likewise, for
blood centers that have distributed blood already, the FDA recommends that the
center advice the transfusion service to quarantine and destroy all blood
components. Lastly, for blood centers that believe a transfusion has been made,
the center should inform the blood transfusion recipient’s physician so that
the physician can monitor the health of the patient. The FDA recommendations on
blood transfusions are a source of guidance on how best to keep the nation’s
blood supply healthy. Although the threat of a Zika virus outbreak in the U.S.
is low, taking safety measures is necessary to remove any slight possibility of
a public health crisis.
