Earlier on Wednesday, health officials said two cases of the virus, known officially as COVID-19, had been detected in the central province of Qom.
The World Health Organization has not yet confirmed the two Iranian coronavirus deaths, but should they be confirmed, it would raise the death toll outside of China to seven.
The news out of Iran comes as coronavirus deaths in China have topped 2,000. More than 75,000 people around the world have contracted the virus, with at least 74,185 of those cases in China.
In Japan, 500 passengers were allowed to disembark from the Diamond Princess cruise ship on Wednesday, which has been under quarantine since early February. The ship, docked off Japan’s coast, became the site of the largest infection center outside of China after more than 620 people tested positive for the virus.
There are still as many as 2,000 people aboard the ship, and authorities said they anticipate it taking several more days before those remaining can be offloaded.
While the International Olympic Committee has not indicated that the Tokyo Games, scheduled to start in late July, will be disrupted by the ongoing outbreak, a former WHO adviser who worked on the SARS outbreak sowed seeds of doubt about the world’s preparedness for such a mass gathering.
“We need to find the best way to have a safe Olympics,” Japanese virologist Dr. Hitoshi Oshitani told reporters at the Foreign Correspondents Club of Japan, according to The Associated Press.
“Right now we don’t have an effective strategy,” he added. “But by the end of July, we may be in a different situation.”
Other sporting events have been canceled or scaled back in recent weeks. Shanghai’s Formula One race, originally scheduled for April, was called off last week.
On Monday, Tokyo officials announced that the city would limit its marathon in March to elite runners and wheelchair participants. The event originally was supposed to include more than 38,000 participants.
The virus, which is in the same family as SARS, MERS and the common cold, causes symptoms similar to pneumonia, which can range from a slight cough to fever and difficult breathing, according to the Centers for Disease Control and Prevention.
There is no approved treatment for COVID-19 yet, nor a vaccine to protect against the virus. Scientists are still working to determine exactly how infectious and severe it is.
