She first tested positive in late January and was discharged from hospital after recovering on 1 February, according to the statement.
Japan's Health Minister Katsunobu Kato said in parliament the central government would need to review patient lists and keep tabs on the condition of those previously discharged, as health experts analysed the implications of testing positive for the virus after an initial recovery.
NYU School of Medicine professor of microbiology and pathology Philip Tierno Jr said much remained unknown about the virus, and it was possible the disease was bi phasic, meaning symptoms could go away before returning again later on.
"Once you have the infection, it could remain dormant and with minimal symptoms, and then you can get an exacerbation if it finds its way into the lungs," Prof Tierno said.
"I'm not certain that this is not bi phasic, like anthrax."
The second positive test came as the number of confirmed cases in Japan rose to 186 by Thursday, from about 170 the day before. ■
