The head of the World Health Organization (WHO) has warned that the coronavirus pandemic is a long way from being over amid the largest daily rise in global cases.
The WHO said 106,000 new cases had been reported to them in the last 24 hours.
Director-General Tedros Adhanom Ghebreyesus has expressed particular concern about rising infections in low and middle-income nations.
The warning comes as the total number of cases approach 5 million.
The grim milestone looks set to be reached less than two weeks after the world hit the 4m mark.
Experts warn the true number of infections is likely to be far higher, with low testing rates in many countries skewing the data.
More than 326,000 people are known to have died with coronavirus around the world, according to Johns Hopkins University tracking.
The US remains the worst-hit country, with more than 1.5m cases and 92,000 deaths so far.
What did the WHO say?
"In the last 24 hours, there have been 106,000 cases reported to WHO - the most in a single day since the outbreak began," Dr Tedros told a Wednesday news conference.
"Almost two-thirds of these cases were reported in just four countries," he added.
Dr Tedros later warned the world still had "a long way to go in this pandemic".
His warning came as a number of countries, including the US, begin to loosen lockdown restrictions.
Dr Mike Ryan, the WHO's emergencies director, also spoke out at the latest briefing against the use of malaria drugs chloroquine and hydroxychloroquine in relation to Covid-19.
- If you have symptoms of the coronavirus, call the NZ Covid-19 Healthline on 0800 358 5453 (+64 9 358 5453 for international SIMs) or call your GP - don't show up at a medical centre
It came after US President Donald Trump said he had been taking the medication in an attempt to ward off the virus, despite his own public health officials warning about its use.
"At this stage, (neither) hydroxychloroquine nor chloroquine have been as yet found to be effective in the treatment of Covid-19, nor in the prophylaxis against coming down with the disease," Dr Ryan said.
"In fact, the opposite, in that warnings have been issued by many authorities regarding the potential side effects of the drug."
