Officials have said that at least four people in Florida have contracted the Zika virus and warn that the virus now appears to be spreading domestically either through contact with mosquitoes or direct human-to-human transmission. Until recently, the virus only appeared in individuals infected outside of the United States, primarily in South America.
In an alarming development, according to CNN, federal, state and local officials have been deployed to canvas neighborhoods in Florida. The stated purpose is to ask questions, request urine samples and determine the spread of the virus.
Officials believe the local transmission is confined to a small area north of downtown Miami within a single ZIP code. However, local, state and federal health officials are continuing their investigation, which includes going door-to-door to ask residents for urine samples and other information in an effort to determine how many people may be infected. Additional cases are anticipated.
