Zika Virus Infection in Patient with No Known Risk Factors, Utah, USA, 2016
نویسندگان
چکیده
In 2016, Zika virus disease developed in a man (patient A) who had no known risk factors beyond caring for a relative who died of this disease (index patient). We investigated the source of infection for patient A by surveying other family contacts, healthcare personnel, and community members, and testing samples for Zika virus. We identified 19 family contacts who had similar exposures to the index patient; 86 healthcare personnel had contact with the index patient, including 57 (66%) who had contact with body fluids. Of 218 community members interviewed, 28 (13%) reported signs/symptoms and 132 (61%) provided a sample. Except for patient A, no other persons tested had laboratory evidence of recent Zika virus infection. Of 5,875 mosquitoes collected, none were known vectors of Zika virus and all were negative for Zika virus. The mechanism of transmission to patient A remains unknown but was likely person-to-person contact with the index patient.

US probes first apparent non-sexual person-to-person Zika transmission and first domestic outbreak.
A Utah man who cared for an elderly male relative infected with Zika virus has tested positive for the disease, despite not traveling to any known Zika zone. The case has raised new questions about how the disease may spread. It came in a week when the first apparent US case from local mosquito bite appeared in Florida, and a week after the first report of female-to-male sexual transmission in ...

Zika virus is a mosquito-borne flavivirus that is becoming a new global threat. Currently, serologic (ELISA) and molecular (RT-PCR) testing make the diagnosis of Zika virus infection. There is no specific drug available for Zika virus infection, and treatment is supportive based on reducing symptoms of disease. Protection against mosquito bites is the most effective way to prevent the infection...

Before the recent outbreaks of Zika virus, few people have ever heard of its name. Even virologists had paid little attention to this member of the Flaviviridae family. Hence, up to January 2016, only 269 articles about Zika virus had been indexed in PubMed compared to the 9187 articles related to dengue virus. However, declaration of the World health organization (WHO) about the global Zika vi...

Further investigation of the role of each type of these cytokines during Zika virus infection is urgently needed. The dendritic cell (DC) is one of the main target cells during infection by various flaviviruses, for examples, DENV, WNV and presumably the most potent antigen-presenting cell (APC)s. Blood DCs of convalescent Zika-virus infection patients demonstrated similarly effective antigen c...
