Over the past four years, we’ve learned tough lessons about the balancing act of public health. Recent coronavirus research has highlighted the need to carefully weigh the benefits and harms of any action taken to mitigate the impact of the disease.
We need clarity on what has worked and what hasn’t in the fight against the coronavirus. One objective of a study was to understand more about this. Here’s what was found out…
Was the spread of the new coronavirus in nursing homes inevitable?
Early in the pandemic, being a resident or staff member in a care home carried the highest risk of death from coronavirus. The virus spread to nursing homes as elderly patients were discharged to make room for new hospitalizations. It was nearly impossible to stop infectious diseases from spreading within nursing homes, even if all patients were tested before being transferred to hospital, as tests can be negative until the person becomes infectious.
Did the personal protective equipment really work?
The importance of personal protective equipment (PPE) to reduce the risk of infection in hospitals and nursing homes was widely accepted even before COVID-19. The lack of availability of PPE was one of the main factors influencing coronavirus transmission in nursing homes.
Early in the pandemic, the benefits and risks of non-pharmaceutical interventions (NPIs) in the community were uncertain. NPIs such as closing schools and banning public gatherings were effective at reducing the spread of the virus.
Did wearing a mask help protect against coronavirus?
Wearing masks did reduce community transmission of coronavirus, at least until the Omicron variant emerged. The value of masks in schools is still debated, with some studies showing that mandatory mask-wearing in schools reduced infections at least for the first few weeks.
Has quarantine helped?
Testing and self-isolation should reduce coronavirus transmission, but studies have shown that for this to work, a significant proportion of infected people would need to self-isolate. Self-isolation rates may not have made a significant difference, as many infected people are never identified.
How effective was the lockdown?
Lockdowns have been associated with mental and musculoskeletal health problems. The overall impact of NPIs in relation to their harms is a broader societal debate beyond just a scientific question.
How effective has the vaccine rollout been?
Rapid development of effective vaccines has been a real success during the pandemic, preventing many more deaths. However, the vaccines did not create herd immunity and eradicated the virus. They also had side effects, such as blood clotting and heart inflammation. Advancements in vaccine science during the pandemic may benefit other infectious diseases for decades to come.
