Zika and microcephaly: first trimester of pregnancy most critical
A new analysis of data from the 2013-2014 Zika epidemic in French Polynesia by scientists from the Institut Pasteur, Paris, and their French Polynesian colleagues has confirmed the incidence of grouped cases of microcephaly and quantified the risk of microcephaly associated with the virus. Using innovative mathematical modeling techniques, their research shows that the risk of microcephaly is...

Culex mosquitoes do not transmit Zika virus
Since the first cases of infection were identified in Brazil, in May 2015, the Zika virus has spread to over 46 countries in America. Several hypothesis are discussed to explain the extent of the epidemic and the rapidity with which the virus has invaded the continent. The transmission could be facilitated by the absence of immunity of the American populations as the virus comes from Africa but...

Mystery of the Cape Verde Zika outbreak solved
Although Zika virus has been responsible for several outbreaks across the planet over the past decade, African countries have remained relatively exempt. But Cape Verde is a notable exception, having experienced a large outbreak in 2015-2016. How can this be explained? Scientists shed light on this seeming paradox.

How Zika virus induces congenital microcephaly
A team of researchers from ZIKAlliance discovers a specific mechanism of the infectionEpidemiological studies show that in utero fetal infection with the Zika virus (ZIKV) may lead to microcephaly, an irreversible congenital malformation of the brain characterized by an incomplete development of the cerebral cortex. However, the mechanism of Zika virus-associated microcephaly remains unclear. An...

Zika: silent long-term circulation in Thailand
The circulation of the dengue virus for the past sixty years in South-East Asia is relatively well known. For Zika, the situation is much less clear. In an attempt to shed light on Zika circulation, scientists from the Institut Pasteur and the CNRS, in collaboration with US teams and the Thai National Institute of Health, decided to investigate the history of the Zika virus in Thailand. They made...

Zika: indigenous cases for the first time in mainland France
For the first time in mainland France, people have contracted the Zika virus. Unlike "imported" cases of the disease, reported by people returning from a trip abroad, these individuals were infected following a mosquito bite in France. Even though they have since recovered, these indigenous cases are a cause of concern for health authorities. The Institut Pasteur's experts took the opportunity to...

Zika outbreaks fostered by virus-permissive mosquitoes
What factors facilitate the emergence of a previously unknown virus in the human population? Scientists from the CNRS, the Institut Pasteur and the IRD, in collaboration with the Institut Pasteur International Network and with several other institutions worldwide, have helped answer that question for the Zika virus. Their study sheds light on regional and continental disparities in Zika...
