The COVID-19 pandemic is 'one big wave', not seasonal, Reuters reported referring to the spokesman for the World Health Organization (WHO) Margaret Harris.

“People are still thinking about seasons. What we all need to get our heads around is this is a new virus and...this one is behaving differently,” Margaret Harris told a virtual briefing in Geneva, urging vigilance in applying measures to slow transmission that is spreading via mass gatherings.

Besides, she noted, it should not be assumed that the virus will stop spreading in the summer in the Northern Hemisphere since COVID-19 is not like influenza, which tends to spread seasonally.
