Before a substantial response was realized, the incidence of Zika virus infections in the western hemisphere began to fall almost as fast as they had risen.
Researchers’ to-do list for tackling the Zika virus is daunting, however progress has been made.
Since 2016, when Zika was declared by the World Health Organization (WHO) as a public health emergency of international concern, the virus has become established in more than 80 countries.
Research found dual Zika/dengue immunity conferred by cytotoxic T-cells.
Some modelling exercises suggest that Zika virus infection could become endemic.
This factsheet offers employers and workers information on how to prevent and manage occupational exposure to Zika virus.
Zika virus is mutating so quickly in Brazilian patients that different serotypes of the pathogen could appear, hindering vaccine development and impairing the effectiveness of existing diagnostic tests.
The test accurately identified infections in 81 percent of positive samples, and incorrectly identified infection in 14 percent of negative samples.
Researchers report that three quarters of US mainland counties have an environment that can harbor Aedes aegypti and Aedes albopictus mosquitoes, which are capable of spreading Zika, dengue, chikungunya, and yellow fever viruses.
It is unknown whether there will be a viable market for a Zika vaccine, once one is eventually approved.
