Unravelling mother to baby transmission of Zika virus
(Frontiers) Researchers have discovered that when a pregnant mother is infected by Zika virus, it can remain in the placenta for months, causing damage that can be dangerous to the fetus. These findings advance our understanding of mother to baby transmission and provide the groundwork for the future development of drugs and vaccines.

Prior Zika virus infection increases risk of severe dengue disease
(University of California - Berkeley) A new study led by researchers at the University of California, Berkeley, finds that people who have antibodies to the mosquito-borne Zika virus are more vulnerable to developing dengue disease. This immune interaction, called antibody-dependent enhancement, could complicate the search for a safe and effective vaccine that protects against Zika without also increasing the risk of dengue.

Zika virus infection enhances future risk of severe dengue disease
The Zika pandemic sparked intense interest in whether immune interactions among dengue virus serotypes 1 to 4 (DENV1 to -4) extend to the closely related Zika virus (ZIKV). We investigated prospective pediatric cohorts in Nicaragua that experienced sequential DENV1 to -3 (2004 to 2015), Zika (2016 to 2017), and DENV2 (2018 to 2020) epidemics. Risk of symptomatic DENV2 infection and severe disease was elevated by one prior ZIKV infection, one prior DENV infection, or one prior DENV infection followed by one ZIKV infection, compared with being flavivirus-naïve. By contrast, multiple prior DENV infections reduced deng...

Africa: Mosquitoes - the Devastating Impact On Global Health
[Malaria Consortium] On World Mosquito Day, Malaria Consortium calls for the international community to reflect on the devasting impact the mosquito has on global health. In 2018, there were over 228 million malaria cases throughout the world and a global death toll of 405,000. But mosquitoes are responsible for transmitting more than just malaria - from zika virus to yellow fever, dengue, chikungunya, Japanese encephalitis and many more - collectively adding another 500 million cases of people burdened with febrile disease ea (Source: AllAfrica News: Malaria)

Study provides insights into how Zika virus suppresses the host immune system
(University of California - Riverside) A research team led by scientists at the University of California, Riverside, has outlined how the Zika virus, which constituted an epidemic threat in 2016, suppresses the immune system of its host. The work provides valuable structural and functional information on the interaction between ZIKV and its host and offers a framework for the development of vaccines and antivirals.

Science, Medical Groups Express Support for Fetal Tissue Research
The American Institute of Biological Sciences joined a coalition of 90 scientific, academic, and medical groups to express support for the continued use of human fetal tissue in biomedical research.
In a July 28, 2020, letter to the National Institutes of Health (NIH) Human Fetal Tissue Research Ethics Advisory Board, the groups argued, in part: “The long-standing existing review process for fetal tissue research ensures that research using fetal tissue is scientifically meritorious, legal, and ethically sound. The legal framework for this research prohibits people from profiting from acquiring, receiving, or transf...

Researchers uncovered the Zika virus mutation responsible for quick spread, birth defects
(University of Texas Medical Branch at Galveston) A multidisciplinary team from The University of Texas Medical Branch at Galveston has uncovered a Zika virus mutation that may be responsible for the explosive viral transmission in 2015/2016 and for the cause of microcephaly (babies with small heads) born to infected pregnant women. The study is currently available in Proceedings of National Academy of Sciences. (Source: EurekAlert! - Infectious and Emerging Diseases)
