Coronavirus: Global death toll from COVID-19 ticks over 400,000

The global death toll for coronavirus now passed a bleak new milestone - but researchers say the true scale of the disease is probably much worse than the numbers suggest.

Health experts at John Hopkins University say the number of COVID-19 deaths has now officially ballooned to more than 400,000, while infections have surpassed 6.8 million.

However they believe the death toll is a substantial undercount, because many who have died in the six months since COVID-19 emerged weren't tested for the disease.

And that's been exacerbated in recent days after Brazil - which has recorded the highest number of coronavirus deaths in the world after the US and the UK - stopped publishing new COVID-19 data.

By Saturday (local time), Brazil had recorded more than 690,000 infections and 36,000 deaths from the virus - but it'll now be difficult for the World Health Organization (WHO) to get a handle of the outbreak there.

Over the weekend Brazilian President Jair Bolsonaro defended his government's decision to stop making COVID-19 totals public, tweeting that deaths and infections are "not representative" of the South American nation's health situation.

However Bolsanaro's fiercest critics - many of whom are health experts - say it's a desperate attempt to hide the real scale of the pandemic in Brazil.

And it's not just Brazil; both North Korea and China have been accused of hiding death and infection tolls during the global outbreak.

Last week, New Zealand's Director-General of Health said despite our own success, it's important to note that the pandemic is still a widespread problem overseas.

"It's easy for us in our very privileged situation here in the country to forget what is happening internationally," Dr Ashley Bloomfield told media last Thursday.

"It's important to recognise that the highest number of cases reported to the WHO since the pandemic started, in any one day, was just three days ago [Monday, June 1]."

New Zealand has recorded 22 deaths and 1504 infections from COVID-19.
