In the past two months, the virus has hit at least 22 states, according to the Centers for Disease Control and Prevention (CDC).
The CDC’s director said on Monday that Texas will be hardest hit.
States that have been hardest hit include: Alabama, Arizona, Arkansas, Colorado, Georgia, Indiana, Kansas, Kentucky, Louisiana, Michigan, Missouri, Nebraska, Nevada, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Utah, Virginia and West Virginia.
The CDC said the outbreak is concentrated in the states of Florida, Georgia and North Carolina.
The outbreak is currently being traced to two counties in Florida: Palm Beach County and Seminole County.
The CDC says Florida is the second-most infected state after Texas with the most people infected, after New York with about 4.7 million.
“The outbreak is rapidly spreading to all 50 states,” the CDC said.
“It’s already spreading in Texas, Georgia with over 6 million cases, and New York state, with over 1.5 million.”
According to the CDC, Florida is one of three states where Zika is already known to have been circulating in the state.
The others are Florida and Georgia, with the first reported case being in Georgia on March 22.
Texas and Georgia were the first states to be hit by the virus, with a total of 14 confirmed cases and more than 1,600 deaths in the first two months.
It was reported on Monday morning that Texas was still recovering from the spread of the virus.
A Texas Health Presbyterian Hospital emergency room nurse told the Dallas Morning News that she has seen several patients with fever and vomiting and is seeing them every two or three days.
Officials said they are working to get some additional patients in the hospital, but said that it is still too early to say if they will receive treatment.
A spokeswoman for Texas Health said it is too soon to say whether anyone in the Texas Health care system is in immediate danger.
She said a Texas Health emergency room will continue to provide medical care to patients until further notice.
Health officials are also continuing to fight the spread.
Meanwhile, some people are taking precautions.
In the last two weeks, people have started taking precautions, including using a mask, washing their hands often, and avoiding wearing masks in public.
