Key points from the April 2021, Volume 1 report

7-day average of new COVID-19 cases

  • 153 million global COVID-19 cases reached, 3.2 million deaths.
  • Case numbers surging in every region, especially in Asia and South America.
  • Seven-day rolling average of daily global cases has more than doubled since February 2021.
  • While India’s outbreak is the world’s largest, many other countries across Asia are experiencing severe second, third and fourth waves.
  • Steadily increasing new cases in Timor-Leste; declines in Papua New Guinea although testing is low so the reported rates under-represent the true extent of spread.
  • Of the 295 active COVID-19 cases in Australia, all but five are in hotel quarantine.

Implications for the Australian COVID-19 Response

  • New cases continue to increase rapidly across all regions, particularly in Asia and South America. India’s second wave is unprecedented and true numbers of deaths are up to 24 times higher than official counts.
  • High vaccine coverage has slowed infections in the USA, UK and Israel.
  • Despite high vaccine coverage, Chile is in the midst of a severe third wave which many experts put down to poor adherence to public health precautions and premature relaxation of restrictions.
  • Inconsistent implementation of hotel quarantine remains the main threat to Australia’s enjoyment of low community transmission, at a time when COVID-19 is spreading at a record pace in other countries.
