Answer:
Assuming that the reported cases refer to Zika cases, the best immediate action to recommend would be to institute a public ban on traveling to and from Zika-prone countries. This measure can help prevent the spread of the virus to new areas and reduce the number of cases reported in the current affected areas. It is also important to continue educating the public about the risks of Zika transmission and how to prevent mosquito bites through the use of insect repellent, wearing long-sleeved clothing, and removing standing water where mosquitoes breed.
