The COVID-19 pandemic is still expanding, but the rise in cases and deaths has slowed globally, except for southeast Asia and the eastern Mediterranean regions, the World Health Organization (WHO) said.

In its latest epidemiological update, issued on Monday night, it said that the Americas remains the hardest-hit region, accounting for half of newly reported cases and 62 percent of the 39,240 deaths worldwide in the past week.

"Over 1.7 million new COVID-19 cases and 39,000 new deaths were reported to WHO for the week ending 23 August, a four percent decrease in the number of cases and (a 12 percent decrease) in the number of deaths compared to the previous week," the WHO said.

Southeast Asia, the second most affected region, reported a jump accounting for 28 percent of new cases and 15 percent of deaths, it said. India continues to report the majority of cases, but the virus is also spreading rapidly in Nepal.

In WHO's eastern Mediterranean region, the number of reported cases rose by four percent, but the number of reported deaths has consistently dropped over the last six weeks, the WHO said. Lebanon, Tunisia and Jordan reported the highest increase in cases compared to the previous week.

The number of cases and deaths reported across Africa decreased by eight percent and 11 percent respectively in the past week, "primarily due to a decrease in cases reported in Algeria, Kenya, Ghana, Senegal and South Africa" it said.

"In the European region, the number of cases reported has consistently increased over the last three weeks," it said. "However, only a slight decrease (1 percent) was reported in the most recent week, and the number of deaths have continued to decrease across the region.”

In WHO's western Pacific region, the number of new cases dropped by five percent, driven by less spread in Japan, Australia, Singapore, China and Vietnam. South Korea reported an 180 percent jump in cases, 'mainly due to an increase in cases associated with religious gatherings"

More than 23.67 million people have been reported to be infected by the coronavirus globally and 813,789​ have died, according to the latest data from Johns Hopkins University on Tuesday.
