HAVANA, Feb. 28 (Xinhua) -- The Cuban Ministry of Public Health reported 618 new cases and four deaths of the novel coronavirus disease (COVID-19) on Sunday, the lowest number of daily cases in the last three weeks.
With these new infections, the total number of confirmed cases rose to 49,779 and the death toll reached 322, according to the ministry's national director of hygiene and epidemiology, Francisco Duran.
In his daily television report, Duran said the lower number of cases shows "that the pandemic is being controlled, although the problem has not been resolved."
The highest contagion rates have been reported in Havana over the last two weeks, with 203 cases per 100,000 inhabitants.
Duran warned about the need to increase the protection of young people, after 84 children, adolescents and young people were diagnosed with the disease over the last day.
In Havana, authorities are continuing to apply protective health measures, including limits on mobility and enforcing the use of face masks.
Cuba is currently developing four vaccines that are at different phases of clinical trials, with the government aiming to immunize 11.2 million people this year.
