What is the situation elsewhere?
Countries across Europe are registering an increase in daily numbers amid fears of a resurgence of the virus.
Local lockdowns have been imposed in the worst-hit areas, and people have been appealed to cover the face and comply with social security regulations.
Other countries that have witnessed the resurgence of the virus include Peru, Israel, South Korea and Australia.
On Sunday, police arrested more than 70 protesters in the Australian state of Victoria for breaking domestic orders to restrain them. Around 250 people took part in the protests in Melbourne city, which was promoted by social media groups sharing a conspiracy about the epidemic.
Victoria has been the epicenter of Australia outbreaks for 75% of cases and 90% of deaths.
