Coronavirus is continuing to spread across the world, with nearly 30 million confirmed cases and a death toll close to one million.

Six months after the World Health Organization (WHO) declared it a pandemic, the virus is surging in many countries and some that had apparent success in suppressing initial outbreaks are also seeing infections rise again.

However, the number of confirmed cases during the spring peak is likely to be an underestimate of the true level of infection, as widespread testing was not available in many countries earlier in the year.
