In 2016, the Zika virus spread around the world, causing more than 5,000 cases of microcephaly in South America-Brazil alone. (Archyde.com file photo)
[Compiled by Chen Chengliang/Comprehensive report]As the Wuhan pneumonia (new coronavirus disease, COVID-19) sweeping the world has not yet subsided, a research team in the United States has warned that the Zika virus (Zika virus) may cause mothers to give birth to babies with microcephaly. Zika virus) is very prone to mutation, and it may become more contagious following another small mutation, and may break through the original immunity, and a large outbreak of Zika virus may occur at any time.
According to the BBC, researchers at the La Jolla Institute for Immunology in California, published in the journal Cell Reports, pointed out that Zika virus is prone to mutation. Even countries that have previously achieved herd immunity may not be able to withstand a new wave of epidemics.

When the researchers passed the Zika virus from mosquito cells to laboratory mice in the laboratory, some genetic changes occurred, and the mutated virus was also infectious, which means that the Zika virus is easy to mutate, which helps it reproduce and spread. , and even animals that have been infected with dengue will not initiate a cross-immune protective response.
Zika virus can be transmitted by mosquitoes, and the mortality rate of Zika infection is low in most people. Symptoms include fever, rash, joint pain, headache, eye socket pain, muscle pain, nausea, etc., similar to dengue fever, but if a pregnant woman is infected by the virus, the fetus may develop brain damage and be accompanied by microcephaly.
Experts and scholars also mentioned that the virus is a closely related virus of dengue fever, and also said that during the outbreak in 2016, tens of thousands of babies were bitten by Zika virus bugs in the womb before they were born. brain damage at birth
Mosquitoes that transmit Zika virus are found almost all over the world. The Zika virus is mostly spread by mosquitoes, but it can also be transmitted through sex.
