FOCUS ON DELTA VARIANT AS COVID-19 CASES RISE: The COVID-19 Delta variant is spreading around the world. New South Wales has become the third Australian state to announce lockdown rules to combat the virus strain. In other parts of Asia and Europe too there has been a spike in coronavirus cases. China has reported a surge in imported infections in southwestern Yunnan province, which shares a border with Myanmar. As fresh lockdowns are announced in some places, England is celebrating as most restrictions have been lifted. Continuous vigilance around the world coupled with a strong vaccination drive is needed to fight the virus. Stop-gap measures won’t work. [COMMENT BY: Alex Abraham, Senior Associate Editor]
