Latin America and the Caribbean has become the region hardest-hit in terms of deaths related to Covid-19, while India has surpassed two million cases of infection.

The world's worst-affected region has reported 213,120 fatalities, 460 more than Europe, according to an AFP tally based on official data.

Worldwide there have been more than 19 million cases of the virus and over 720,000 deaths from the illness since it was first reported in China at the end of last year.

The virus has flared up again in areas where it appeared to have been curbed and has steadily spread across India and Africa.

India's cases have doubled in three weeks, reaching two million yesterday following a record daily jump of more than 60,000 new infections.

It is only the third country after the United States and Brazil to surpass two million cases.

Official figures show the world's second most populous nation has also recorded 41,500 deaths.

Prime Minister Narendra Modi's government imposed one of the world's strictest lockdowns in late March, with tens of millions of migrant workers losing their jobs almost overnight. But with the economy in tatters, restrictions have been steadily eased.

Experts say the true numbers of cases and fatalities are grossly under-reported as causes of death in the country of 1.3 billion people are rarely properly recorded. The stigmatization of those infected has put off many from getting tested.

However, there have been some positive indicators in Africa, where health authorities warned against complacency amid hopes that the pandemic is peaking in some parts of the continent.

"African countries are doing their best, despite... limitations" such as weak health systems, Mary Stephen of the World Health Organization's Africa office, told AFP.

Some countries have seen declines of around 20% in cases but there remain fears of a second wave.

"Because we don't see many people like we used to see in Italy, like 1,000 people dying (a day), people tend to relax, they think the risk is not so much in Africa," said Ms Stephen.

Much of the world is placing its hopes on an effective vaccine becoming available sooner rather than later.

Up to 100 million Covid-19 vaccine doses could be made available for poorer countries by 2021, Gavi, the Vaccine Alliance, announced.

These vaccines, priced at a maximum of $3 per dose, would be produced at the Serum Institute of India.

In Latin America, which is already the region with the largest number of infections at 5.3 million, deaths continue to soar.

Over the last week, 44% of global fatalities from Covid-19 - 18,300 out of 41,500 - occurred in the region.

More than half the region's infections, some 2.9 million, are in Brazil, which has also recorded 98,500 deaths among its 212 million people.

Only the United States has been worse hit than Brazil. It added 1,062 new deaths on Friday to bring its toll to just over 161,000, according to a tally by Johns Hopkins University.

The second worst-affected country in Latin America, Mexico, passed 50,000 deaths on Thursday.

In the United States, New York Governor Andrew Cuomo said schools could reopen this autumn if they meet certain criteria.

Schools in several US states have reopened for in-person classes - but some have already been hit by large quarantines of students and staff following fresh outbreaks.

The US economy regained 1.8 million jobs in July, according to government data, and the unemployment rate fell to 10.2%, but with Covid-19 cases spiking in several states economists raised concerns that the labour market could take a turn for the worse.
