Scientists believe that Zika virus could become a greater threat to humanity than Ebola, which has so far claimed more than 11,000 lives. This virus is a special danger for all expectant mothers, as it is associated with microcephaly, or incomplete development of the brain and skull in babies. If a woman is bitten by an infected mosquito while she is pregnant, exactly this disorder is one of the consequences for the baby.

zika virus-what to know about

There is no vaccine that would effectively prevent the spread and the doctors explain that the development of such a drug is particularly complicated because it had to be tested on pregnant women.  Symptoms usually appear three to seven days after the bite of infected mosquitoes, and usually include fever, rash, joint pain, eye redness and pain, muscle pain, headache and vomiting.

Virus, therefore, does not represent a major threat to the health of adults, but it has terrible consequences on the development of babies in the womb, as the virus passes through amniotic fluid to the fetus. However, a major problem is the fact that in 80 percent of cases does not come to any symptoms, so women do not even know that they are infected.

Where is present?

This virus was previously diagnosed in the tropics inhabited by large populations of mosquitoes, most in Africa, North and South America, southern Asia and the Western Pacific.
Zika virus was discovered in 1947, but for many years was very rare. Only 2007 was recorded the first spread of infection, and since 2013, there were a number of such cases in the mentioned parts of the world.

What are the symptoms?

The first symptoms occur only a few days after a person is being bitten by a mosquito, and most infected fall into a mild fever and can get a rash. Also conjunctivitis can occur, pain in joints and muscles and fatigue, and symptoms usually last from two to seven days.

What are the potential complications?

Given the fact that epidemics are not recorded before 2007, little is known about the possible consequences of this disease. During the epidemic in French Polynesia in 2013 and 2014, which “coincided” with an epidemic of dengue fever, it is noticed an increasing number of cases of Guillain-Barre syndrome. The potential role of Zika virus in that is still being investigated, but it is interesting that Guillain-Barre syndrome is more often diagnosed in Brazil in 2015 – just during the first epidemic of Zika virus in this country.

Last year, researchers in Brazil also noticed an increased number of children born with microcephaly during this epidemic, however, and this connection is currently still being examined.

What WHO is doing?

To help countries around the world to prepare for and respond appropriately to Zika virus, WHO works with ministries of health to improve laboratories and enabled them to recognize the virus, providing recommendations for treatment and control of infected patients, and supports monitoring and reporting on the spread of the virus and the development of complications.

Also, the World Health Organization helps in exploring potential links between microcephaly and Zika virus.
