At epicenter of Zika outbreak, dengue immunity provided protection

(Yale University) When the Zika virus arrived in the Americas in early 2015, it struck hard, infecting 73 percent of people in one Brazilian community at the epicenter of the pandemic, according to a new study led by the Yale School of Public Health.The study, conducted in collaboration with the Oswaldo Cruz Foundation-Brazilian Ministry of Health and international partners, is published in Science.

This article provides a vision of integrated eco-friendly and sustainable behavioral communication change (BCC), biological control preparedness and resilience approaches, and innovations implementation in Saudi Arabia and GCC for the purpose of controlling the threat of Aedes-linked vector-borne viral diseases. Implementing innovative Aedes-linked arboviral preventive and resilient control measures is pivotal in improving community-based surveillance-response systems, BCC multidisciplinary and empowerment methods, and in enhancing community social mobilization and risk communication strategies. Moreover, boosting social, ...

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...

The clinical outcomes associated with Zika virus (ZIKV) in the Americas have been well documented, but other aspects of the pandemic, such as attack rates and risk factors, are poorly understood. We prospectively followed a cohort of 1453 urban residents in Salvador, Brazil, and, using an assay that measured immunoglobulin G3 (IgG3) responses against ZIKV NS1 antigen, we estimated that 73% of individuals were infected during the 2015 outbreak. Attack rates were spatially heterogeneous, varying by a factor of 3 within a community spanning 0.17 square kilometers. Preexisting high antibody titers to dengue virus were associat...

(CNN) — From climate change to superbugs, the World Health Organization has laid out 10 big threats to our global health in 2019. And unless these threats get addressed, millions of lives will be in jeopardy. Here’s a snapshot of 10 urgent health issues, according to the United Nations’ public health agency: Not vaccinating when you can One of the most controversial recent health topics in the US is now an international concern. “Vaccine hesitancy — the reluctance or refusal to vaccinate despite the availability of vaccines — threatens to reverse progress made in tackling vaccine-prevent...

Authors: Young PR Abstract Arboviruses are a diverse group of vector-borne viruses, many of whose members are the cause of significant human morbidity and mortality. Over the last 30 years, the emergence and/or resurgence of arboviruses have posed a considerable global health threat. The ongoing geographical expansion of the dengue viruses (DENV), along with the explosive outbreaks of West Nile virus (WNV), Chikungunya virus (CHIKV) and more recently, Zika virus (ZIKV) have all served as reminders that new epidemics may emerge at any time from this diversity. A clearer understanding of what mechanisms drive th...

Authors: Kanda PAM, Aguiar AAX, Miranda JL, Falcao AL, Andrade CS, Reis LNDS, Almeida EWRB, Bello YB, Monfredinho A, Kanda RG Abstract Microcephaly (MC), previously considered rare, is now a health emergency of international concern because of the devastating Zika virus pandemic outbreak of 2015. The authors describe the electroencephalogram (EEG) findings in sleep EEG of epileptic children who were born with microcephaly in areas of Brazil with active Zika virus transmission between 2014 and 2017. The authors reviewed EEGs from 23 children. Nine were females (39.2%), and the age distribution varied from 4 to 48&nb...

Conclusion This study has identified a substance in the mucus secreted by a south Indian frog which can kill certain types of flu virus. Researchers often turn to natural substances with known health-giving properties to find potential new drugs for humans. For example, aspirin was developed based on a compound found in willow bark – which had been used in traditional medicine for hundreds of years. Some other drugs – such as some chemotherapy and anticlotting drugs – have also been developed from chemicals found in plants. By isolating the substances that have an effect the researchers can make sure...
