|Zika Virus Disease (Disorder) Dengue Chikungunya|
The study will enroll subjects in several different cohorts including a febrile rash cohort (attempting to capture acute Zika/Chikungunya/Dengue infection), a household cohort (attempting to capture asymptomatic or minimally symptomatic subjects), and a cohort of those with Guillain Barré). Additionally, two subpopulations of the febrile rash cohort that have special follow up. This includes the pregnant population, who will be followed through delivery to determine pregnancy outcomes, and those subjects with neurologic or cognitive manifestations who will be evaluated to determine the spectrum of neurologic disease seen with these diseases.
Subjects with Guillain Barré with potential exposure to Zika virus are of special interest given the severity of disease. Subjects with Guillian Barré do not need to have a preceding illness suggestive of Zika or other viruses. As there are few subjects with Guillain Barré, subjects will be enrolled in two ways - a prospective cohort for subjects with acute Guillain Barré, and a cohort for subjects that had Guillain Barré in the last several years. Data collected systematically from these cohorts will improve the understanding of Zika/Chikungunya/Dengue virus infections.
There are many uncertainties about the number of subjects that meet this case definition. There are limits to the ability to enroll based on staffing and other resources. If there are many cases, an emphasis will be placed on enrolling pregnant subjects and adults with neurologic complications that meet the case definition, as this is the area of highest clinical need. If there are few pregnant women or subjects with neurologic problems that can be enrolled, then any adults or children meeting the criteria can be enrolled. Not all cohorts will be active at all sites, based on the type of facility and type of patients typically seen. If sufficient numbers of certain populations are enrolled (i.e. children born to women infected with Zika), the protocol may be amended to study those populations in more detail.
