I read with dismay a foreign newspaper report which stated that Covid-19 is very likely to stay as our permanent enemy, just like the flu but much worse. Scientists from the University of Minnesota’s Center for Infectious Disease Research and Policy predicted that Covid-19 was more contagious and has a longer incubation period than the flu, meaning it takes longer for symptoms to appear after a person has been infected.
The research also found that it might be at its most contagious before symptoms appear. It also said that even if the pandemic wanes, the virus would continue to circulate in the human population and synchronize with seasonal patterns with less severity over time.
