As the coronavirus pandemic continues its deadly path, dramatic changes in how people live are reducing some instances of other medical problems. Bryn Nelson writes that the irony may hold valuable lessons for public health
Doctors and researchers are noticing some curious and unexpectedly positive side effects of the abrupt shifts in human behaviour in response to the covid-19 pandemic. Skies are bluer, fewer cars are crashing, crime is falling, and some other infectious diseases are fading from hospital emergency departments.
Other changes are unquestionably troubling. American doctors have expressed alarm over a nosedive in patients presenting to emergency departments with heart attacks, strokes, and other conditions, leading to fears that patients are too afraid of contracting covid-19 to seek necessary medical care.1 Calls to poison control centres are up by around 20%, attributed to a rise in accidents with cleaners and disinfectants even before President Trump questioned whether injected disinfectants might stop the virus.2 Calls to suicide prevention lines are skyrocketing, while health experts are fretting about signs of rising alcohol and drug use, poorer diets, and a lack of exercise among those cooped-up at home.3 Millions of people are hungry and unemployed.
But doctors, researchers, and public health officials say the pandemic is also providing a unique window through which to view some positive health effects from major changes in human behaviour. And the pandemic may lead to a public more willing to accept and act on public health messages.
Alice Pong, a paediatric infectious disease physician and the medical director for infection control at Rady Children’s Hospital in San Diego, California, said the hospital has seen a sharp decline in paediatric admissions for respiratory illnesses. These include diseases such as influenza, parainfluenza, respiratory syncytial virus, and human metapneumovirus.
“We track positive viral tests through our hospital lab and those numbers have gone down dramatically since everybody went into quarantine,” Pong told The BMJ. “We do think that’s a reflection of kids not being in day care or school.” The hospital is testing fewer patients, she said, which could be because more children might be staying home with respiratory symptoms. But more serious cases and intensive care unit admissions are down as well, suggesting a true decline in life threatening illnesses.
Beyond the disease reducing effects of social distancing, Pong said she believes children and families are taking advice on hand washing, personal hygiene, and other prevention measures seriously. “I think this is going to be a good lesson for everybody,” she said. ‘‘The public is seeing why public health officials have advised them stay home when they feel sick, for example, and why they’ve emphasised hand washing and covering a cough or sneeze. Kids growing up now will know this is how germs are spread,” Pong said. That message could spread to their families and broaden awareness.Although baseline pollution levels in the US are lower, Burke said a similar 20-30% reduction in pollution would still likely yield significant health benefits. “A pandemic is a terrible way to improve environmental health,” he emphasised. It may, however, provide an unexpected vantage to help understand how environmental health can be altered. “It may help bring into focus the effect of business as usual on health outcomes that we care about,” he told The BMJ. “In some sense, it helps us imagine the future.” Getting there, he says, could instead come through better regulation and technology.
A separate report coauthored by Fraser Shilling, director of the Road Ecology Center at the University of California at Davis, found that highway accidents—including those involving an injury or fatality—fell by half after the state’s shelter-in-place order on 19 March.7 “The reduction in traffic accidents is unparalleled,” and yielded an estimated $40m (£32m; €37m) in public savings every day, the report asserted.
Whereas average traffic speeds increased by only a few miles per hour, traffic volume fell by 55%. Hospitals in the Sacramento region reported fewer trauma related admissions while other reports indicated fewer car collisions with pedestrians and cyclists.
In Washington, collisions on state highways fell even further—by 62%—in the month after the state’s stay-at-home order went into effect on 23 March, compared with the previous year, according to the Washington State Patrol. The question, Shilling said, is whether researchers can learn from the information to design safer transportation patterns. “We’re not going to be guessing anymore about what happens when you take half the cars away,” he said.
Hope this helps u
there is no such positive aspects of covid19 but we can say that due to covid19 we have to impose lockdown and lockdown helps us do ruduce air pollution....
