Prime Minister Fumio Kishida will continue work from his official residence after testing positive for COVID-19 over the weekend, senior government officials have confirmed.

Kishida, who received his fourth shot of a coronavirus vaccine on Aug. 12, is thought to have become infected while on a weeklong vacation that began Aug. 15. The diagnosis was confirmed by doctors Sunday after the 65-year old began experiencing mild symptoms, including a cough and slight fever, on Saturday.

“Given the prime minister’s mild symptoms, we have set up a remote workstation from which he can continue his daily duties as planned,” Chief Cabinet Secretary Hirokazu Matsuno said at a news conference Monday morning.

Japan is experiencing its seventh wave of the pandemic. On Sunday, the nation’s weekly rolling average of new cases per day stood at 218,798, while deaths had increased by 72% over the previous two weeks.

Having accompanied Kishida on the vacation, which included golfing and a visit to a hot spring, both the prime minister’s wife, Yuko, and his eldest son, Shotaro, have been designated close contacts, although they have so far tested negative.

Three of Kishida’s secretaries have also tested positive for COVID-19 over the past month.

The prime minister has advocated for COVID-19 measures that do not disrupt the social and economic activities of the country, but as businesses are increasingly being hit by workforce disruptions caused by the recent rise in infections, lawmakers and health care officials continue to discuss alternative means of responding to the pandemic.

The positive diagnosis arrives amid a difficult time for the government, which is currently under pressure due to pandemic-related issues, a recent rise in regional tensions over Taiwan and continued revelations linking lawmakers to the Unification Church.

“To maintain business as usual during this time, we on the prime minister’s staff will of course provide backup for his duties if and when needed,” Matsuno told reporters.

It has been confirmed that Kishida will not travel to Tunisia later this week to attend the eighth Tokyo International Conference on African Development (TICAD) — which is being co-hosted with the United Nations, the World Bank and the African Union Commission — as had been intended, and will instead participate online.

“Japan attaches great importance to TICAD 8, and the remote working environment put in place will allow the prime minister to participate in conferences as he completes the recommended quarantine period,” Matsuno said.
