A Guatemalan national passed away after contracting rabies.
He was placed in custody of U.S. Immigration and Customs Enforcement (ICE) in Hidalgo.
Federico Mendez-Hernandez was apprehended on the Rio Grande River and showed symptoms of rabies.
Mendez-Hernandez was vomiting, had anxiety, shortness of breath, a rapid heartbeat and trouble swallowing.
After a health screening, he was transported to a Corpus Christi hospital.
Laboratory work showed that the man had rabies associated with a canine rabies virus commonly found in Central America.
According to the U.S. Centers for Disease Control and Prevention, there has never been a confirmed case of person-to-person transmission of rabies outside of organ or tissue transplants.
An investigation is underway to find out who had been in contact with Mendez-Hernandez. because people exposed to Mendez-Hernandez's saliva or tears may need treatment.
According to the CDC, the virus can begin when infected saliva is passed.
Even though no such human-to-human rabies virus transmission has been documented it is possible someone could have contracted the virus so they are not taking any chances.
Public health officials will be interviewing people who came in contact with Mendez-Hernandez while he was in the U.S.
