Former WBC heavyweight champion Vitali Klitschko, who is also the mayor of Kiev, Ukraine, is taking deeper measures to prevent the spread of the coronavirus.

Klitschko has been very aggressive in trying to defend Ukraine's capital in the fight against the COVID-19 pandemic.

Starting on Monday, March 23, Kiev's public transport will be available only for medical workers, rescuers, law enforcement officers, utility service workers, the staff of groceries and pharmacies.

"Amid the rapid spread of coronavirus, we need to take more effective measures to limit social contacts in our city. That is why, on Monday, March 23, the capital’s public transport will carry only those passengers who go to work at critical enterprises of our city - medical workers, rescuers, law enforcement officers, utility service workers, the staff of groceries and pharmacies,” Klitschko said in his video address, an Ukrinform correspondent reports.

Restrictions on the operation of public transport will not apply to personal vehicles.

As previously reported on BoxingScene.com, a national lockdown was introduced in Ukraine until April 3 to counteract the spread of coronavirus infection. In particular, educational establishments and all shops except groceries, pharmacies, gas stations and banks were closed.

The operation of subways in Kiev, Kharkiv and Dnipro were suspended. The intercity and inter-regional road, rail and air passenger transportation was stopped. In addition, foreigners are banned from entering Ukraine and international passenger services are suspended.

As of  March 21, Ukraine confirmed 41 cases of COVID-19. Fifteen new cases were detected in the last 24 hours.

Klitschko retired from the sport with a record of 45-2 with 41 knockouts. He made his final ring appearance, and final defense of the title, with a stoppage of Manuel Charr in September of 2012. The vacant belt was captured by Bermane Stiverne in 2014, who lost it to Deontay Wilder the following year.
