Following the first human case of H6N1, or bird flu, doctors in Taiwan have warned for people to be wary of unexpected pandemics caused by animals carrying diseases.

According to BBC News, a woman in Taiwan has recovered from her case of bird flu, but was reported as the first human to come down with the illness earlier this year. There have also been no other reports of the illness since.

The exact source of the woman's illness has not been determined, but her neighbor bred geese, ducks and chickens. H6N1 was not known to infect humans and many health experts are trying to prevent another pandemic like swine flu from happening again.

Despite the patient's recovery and lack of other instances, researchers with Taiwan's Centers for Disease Control and Prevention published a report in the journal Lancet Respiratory Medicine.

"The occurrence of a human case of H6N1 infection shows the unpredictability of influenza viruses," the report read. "Our report highlights the need for influenza pandemic preparedness, including intensive surveillance for ever evolving avian influenza viruses."

Wendy Barclay, a professor at Imperial College London, wondered if the illness was new or previously unnoticed. She said modern technology most likely played a big role in the matter.

"Is this a truly new thing or are we now just better at seeing it?," she said. "This is a single case with no evidence of human transmission, but as always we should keep an eye on it and do studies to see how close it is to being able to spread between humans."

Dr. Ho-Sheng Wu, the report's lead author, said that further research will be needed to assess the illness' potential threat, according to HealthDay News.

"As these viruses continue to evolve and accumulate changes, they increase the potential risk of human infection." Wu said in a statement. "Further investigations are needed to clarify the potential threat posed by this emerging virus."
