A person in Hawaii was placed in isolation after exhibiting possible symptoms consistent with Ebola, state health officials confirmed.

The patient is being treated at the Queen’s Medical Center in Hawaii. Authorities say they are being especially cautious due to heightened concern about Ebola – but at this point, the patient could have a number of illnesses.

“The hospital is being very careful, as they should be, to take precautions making sure the patient is in isolation and making sure the people and the public stay safe,” Dr. Melissa Viray of the Hawaii Department of Health told ABC affiliate KITV. “That being said, it’s still an if. This is not a for sure thing.”

The situation comes days after a man in Texas – identified as Thomas Eric Duncan – became the first person diagnosed with Ebola in the United States.

Ebola has killed more than 2,900 people and infected more than 3,300 others since the outbreak began in March.
