New insights into how the Zika virus causes microcephaly A study published today in Science shows that the Zika virus hijacks a human protein called Musashi-1 (MSI1) to allow it to replicate in, and kill, neural stem cells. Almost all MSI1 protein in the developing embryo is produced in the neural stem cells that will eventually develop into the baby's brain, which could explain why these cells are so vulnerable to Zika.
The Importance of Continuous Learning in the Time of Zika According to the World Health Organization (WHO) and the Pan American Health Organization (PAHO), pregnant women have the same risk of being infected with Zika virus, which is transmitted by the bite of infected Aedes mosquitoes, as the general population.
Questions about Zika Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito (
Aedes aegypti and
Aedes albopictus). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms. However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects.
Microcephaly Zika and microcephaly: Microcephaly is a birth defect where a baby’s head is smaller than expected when compared to babies of the same sex and age. Babies with microcephaly often have smaller brains that might not have developed properly.
New Year update about Zika virus The Zika virus (ZIKV) is a mosquito-borne virus originally discovered in the Zika Forest area in Uganda in 1947. It was not considered a relevant pathogen for humans until the outbreaks of fever illness that occurred in the Pacific area in 2007, and later in 2013-14. However, it was its arrival and dramatic spread in Brazil and other Latin American and Caribbean countries that alarmed public health authorities and the scientific community.
Temperatures could accelerate the success of a Zika vaccine As warmer temperatures herald annoying mosquitoes, the researchers are feverishly working on several promising vaccines against zika, a virus known to infect humans through the bite of this insect. The speed and debilitating effects of last year's zika outbreak in the Western Hemisphere generated a race to develop a vaccine. Just over a year after this pandemic was declared a global health emergency, a group of volunteers are undergoing preliminary testing.
Babies with Zika virus malformations Three babies were born with malformations associated with infection with the Zika virus, and three others appear as probable cases. The most common malformation is microcephaly, but other associated complications may also occur as part of congenital zika syndrome (SZC) or congenital syndrome associated with zika. Health authorities had predicted the increase in this type of cases. Only last year, it was possible to confirm with laboratory tests the infection with this virus of 150 pregnant women. Of these, between 25% and 30% has already given birth.
Starts human trial of zika vaccine Sinergium Biotech has been investigating a safe immunization against zika virus. It is expected that this year will begin tests in humans, after obtaining good results in mice in the preclinical stage. The zika virus expands throughout the region, and in the summer the countries seek to limit the circulation of the disease, transmitted by the same mosquito as dengue.
Prevent Mosquito Bites Use Environmental Protection Agency (EPA)-registered insect repellents with one of the active ingredients below. When used as directed, EPA-registered insect repellents are proven safe and effective, even for pregnant and breastfeeding women.
Identified the seven most harmful proteins in zika virus A group of US scientists has been able to identify the 7 most harmful proteins of the Zika virus, a finding that may help better understand how that disease attacks the cells of the human body, according to a study published in Proceedings of the National Academy of Sciences.
Zika virus Overview Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito (
Aedes aegypti and
Aedes albopictus). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms.
Half of Brazilian Women Are Avoiding Pregnancy Because of Zika Researchers found that a majority of women in Brazil are avoiding pregnancy because of fears surrounding Zika. Brazil has undeniably been the country hardest hit by the latest epidemic of Zika virus; it leads the world in confirmed cases of infection with nearly 110,000 cases, according to the latest data from the Pan American Health Organization.
Vaccine against zika is successful in mice The successful results of the first tests of the vaccine can be tested this year in humans. A zika vaccine developed by researchers in Brazil and the United States was effective in tests with laboratory mice and could be tested this year in humans, Brazilian authorities said. The successful results of the first tests of the vaccine developed jointly by researchers from the University of Texas, the National Institute of Health of the United States and the Brazilian state center for health studies Institute Evandro Chagas, were highlighted Monday in a published article In the journal Nature Medicine.
What health communicators can learn from Ebola Since the World Health Organisation declared Zika a global public health emergency in February of this year, much attention has been brought to bear on applying lessons learned during the Ebola crisis of 2014-15.
Zika virus precautions and winter travel plans For many Michigan residents, the winter months often include travel to warmer climates. To date, Michigan has confirmed 69 cases of Zika virus disease in travelers, including three pregnant women. All of the Zika cases in Michigan are travel related.
