Experts warn that blockages of coronaviruses must remain until there is a vaccine

  • While the lockdowns have been effective in curbing the spread of the new coronavirus, experts warn that loosening restrictions before a vaccine is available can lead to a resurgence of cases.
  • A new study by researchers at the University of Hong Kong says there is still a “significant risk” of new infections, especially from travelers, and the virus must be closely monitored to prevent a new epidemic.
  • “Although control policies such as physical alienation and behavior change are likely to be sustained for some time, finding a proactive balance between resuming economic activities and keeping the reproductive number below one is probably the best strategy until effective vaccines are widely available, “said lead researcher Joseph Wu.

A new study by researchers at the University of Hong Kong has found that the lock-in measures have helped stem the “first wave” of the spread of the new coronavirus. But experts warn that loosening restrictions before a vaccine is available can lead to a resurgence of cases.

The study, published Wednesday in the Lancet medical journal, was first published by The Guardian. The research is based on modeling the spread of the virus in China, which appears to have been contained as the country has not reported any new domestic cases since March 19.

“The first wave of COVID-19 outside of Hubei has declined due to aggressive non-pharmaceutical interventions,” the study found.

Research has shown that China has been able to dramatically reduce the number of replicates of the virus – that is, the average number of people a person can infect – from two or three to just under a.

But the study warned that there is still a “significant risk” of new infections, especially among travelers. He stressed that the spread of the virus must be closely monitored in order to prevent another epidemic, or “second wave” of the disease and to achieve “an optimal balance between health and economic protection”.

“Although control policies such as physical alienation and behavior change are likely to be sustained for some time, finding a proactive balance between resuming economic activities and keeping the reproductive number below one is probably the best strategy until effective vaccines are widely available, “said Joseph Wu, who leads research on modeling of infectious diseases at the School of Public Health at the University of Hong Kong and co-directed the ‘study.

The virus has infected more than 1.5 million people worldwide and killed more than 88,000 people. China, once the epicenter of the disease, has reported just over 82,000 cases and 3,337 deaths.

According to Rebecca Cairns of Business Insider, more than 40 research teams are developing a vaccine for COVID-19. But according to The Oxford Vaccine Group, producing an effective and safe vaccine can take between five and ten years, although research can often be accelerated during an epidemic due to increased funding.

“Given the current severity of the crisis, efforts are underway to accelerate the development of a COVID-19 vaccine in as little as 12 to 18 months,” said Abe Malkin, MD, founder and director MD Concierge MD in Los Angeles.

Yet other experts have warned that producing a viable vaccine is a long and intensive process, and clinical trials can take months.

“It sounds promising, but there is no guarantee that any of the vaccines will elicit a sufficiently strong immune response,” said Brendan Wren, professor of microbial pathogenesis at the London School of Hygiene & Tropical Medicine.
