The United States has been hit with the first known case of the new strain, coronaviruses H5N1 and H7N9, in the southern state of Texas.
The virus was first detected on August 25 and spread rapidly in the months that followed.
More than 50 people in the U.S. have been infected, including two children, according to the Centers for Disease Control and Prevention (CDC).
But the most common strain of the virus, H5, has not been found in any cases.
Now the virus has spread across the border, into Mexico.
In Texas, more than 300 cases have been reported, according the Texas Health and Human Services Commission (HHSC).
On Tuesday, the Texas Department of State Health Services (SDHS) reported the first cases in the Rio Grande Valley, a densely populated region that covers parts of Texas and Oklahoma.
The county is home to the nation’s second-largest concentration of Hispanics, and it’s a place where many people of color are under-represented in the workforce, including in the health care sector.
The state’s health department has opened an office to help residents and others with contact tracing.
The department has been urging the public to take precautions, including avoiding outdoor gatherings.
“We need to get people indoors,” said Susan R. Bader, a Texas Health Department spokeswoman.
“People need to be aware of the fact that this is happening.”
Bader also said that people should stay away from certain public areas such as beaches, parks, and schools, and report any unusual activity, such as a walk with friends or children.
The CDC says that the virus is not known to spread through air or water.
It has been reported in the South, Southwest, and Midwest, and has also been reported to Canada.
As of Thursday, there have been 2,924 confirmed cases in Texas, according data from the Texas Tribune, which tracks cases from the state.
Texas is the only state to report an outbreak in the first five days.
There are a total of 15,054 confirmed cases and 2,814 deaths, according at the CDC.
