Research from the University of Hong Kong has concluded that controls must remain in place around the world until a vaccine is discovered for the coronavirus.
The study, based on the Chinese experience, looks into the dangers of the second wave of covid-19 outbreaks occurring after the first wave dies down.
In China, aggressive measures were put in place to control the spread of the virus and helped to end the first wave of infections. However, a second wave is a real possibility according to Professor Joseph Y Wu who co-led the research.
He said that without herd immunity against covid-19, cases could very easily surge again as people resume daily life. He also warned economic activity, particularly importing and exporting could create a second wave of the virus, saying:
“Although control policies such as physical distancing and behavioral change are likely to be maintained for some time, proactively striking a balance between resuming economic activities and keeping the reproductive number below one is likely to be the best strategy until effective vaccines become widely available.”
The study uses analysis from local Health Commission data for confirmed coronavirus cases in four major Chinese cities between mid-January and the end of February.
