As New York, California and different states start to see their numbers of recent COVID-19 instances stage off and even slip, it would seem as if we’re nearing the tip of the pandemic.
President Donald Trump and a few governors have pointed to the slowdown as a sign that the day has come for reopening the nation. “Our experts say the curve has flattened and the peak in new cases is behind us,” Trump mentioned Thursday in asserting the administration’s guidance to states about tips on how to start easing social distancing measures and stay-at residence orders.
But with the nationwide toll of coronavirus deaths climbing every day and an ongoing shortage of testing, well being specialists warn that the nation is nowhere close to “that day.” Indeed, a research launched this week by Harvard scientists means that with out an efficient remedy or vaccine, social distancing measures might have to remain in place into 2022.
Kaiser Health News spoke to a number of illness detectives about what reaching the height stage of instances means and beneath what circumstances folks can return to work and college with out worry of getting contaminated. Here’s what they mentioned.
It’s Hard To See The Peak
Health specialists say to not anticipate a single peak day — when new instances attain their highest stage — to find out when the tide has turned. As with any illness, the numbers want to say no for a minimum of every week to discern any actual pattern. Some well being specialists say two weeks as a result of that might give a greater view of how broadly the illness remains to be spreading. It usually takes folks that lengthy to point out indicators of an infection after being uncovered to the virus.
But getting a real studying of the variety of instances of COVID-19, the illness attributable to the coronavirus, is hard due to the shortage of testing in lots of locations, notably amongst folks beneath age 65 and people with out signs.

Another issue is that states and counties will hit peaks at totally different instances based mostly on how shortly they instituted stay-at-home orders or different social distancing guidelines.
“We are a story of multiple epidemics, and the experience in the Northeast is quite different than on the West Coast,” mentioned Esther Chernak, director of the Center for Public Health Readiness and Communication at Drexel University in Philadelphia.
Also making it laborious to find out the height is the success in some areas of “flattening the curve” of recent instances. The widespread efforts at social distancing had been designed to assist keep away from a dramatic spike within the variety of folks contracting the virus. But that may outcome as an alternative in a flat charge which will stay excessive for weeks.
“The flatter the curve, the harder to identify the peak,” mentioned William Miller, a professor of epidemiology at Ohio State University.
The Peak Does Not Mean The Pandemic Is Nearly Over
Lowering the variety of new instances is essential, but it surely doesn’t imply the virus is disappearing. It suggests as an alternative that social distancing has slowed the unfold of the illness and elongated the course of the pandemic, mentioned Pia MacDonald, an infectious illness skilled at RTI International, a nonprofit analysis institute in North Carolina. The “flatten the curve” technique was designed to assist reduce the surge of sufferers so the well being care system would have extra time to construct capability, uncover higher therapies and finally give you a vaccine.
Getting previous peak is essential, Chernak mentioned, however provided that it results in a comparatively low variety of new instances.
“This absolutely does not mean the pandemic is nearing an end,” MacDonald mentioned. “Once you get past the peak, it’s not over until it’s over. It’s just the starting time for the rest of the response.”
What Comes Next Depends On Readiness
Although Trump mentioned the nation has handed the height of recent instances, well being specialists cautioned that from a scientific perspective that gained’t be clear till till there’s a constant decline within the variety of new instances — which isn’t true now nationally or in lots of giant states.
“We are at the plateau of the curve in many states,” mentioned Dr. Ricardo Izurieta, an infectious illness specialist on the University of South Florida. “We have to make sure we see a decline in cases before we can see a light at the end of the tunnel.”
Even after the height, many individuals are vulnerable.
“The only way to stop the spread of the disease is to reduce human contact,” Chernak mentioned. “The good news is having people stay home is working, but it’s been brutal on people and on society and on the economy.”
Before permitting folks to collect in teams, extra testing must be performed, people who find themselves contaminated should be quarantined, and their contacts should be tracked down and remoted for 2 weeks, she mentioned, however added: “We don’t seem to have a national strategy to achieve this.”
“Before any public health interventions are relaxed, we better be ready to test every single person for COVID,” MacDonald mentioned.
In addition, she mentioned, metropolis and county well being departments lack staffing to contact individuals who have been close to those that are contaminated to get them to isolate. The instruments “needed to lift up the social distancing we do not have ready to go,” MacDonald mentioned.
You’re Going To Need Masks A Long Time
Whether folks can return out to renew each day actions will rely upon their particular person danger of an infection.
While some states say they may work collectively to find out how and when to ease social distancing requirements to restart the financial system, Chernak mentioned a extra nationwide plan will likely be wanted, particularly given Americans’ need to journey inside the nation.
“Without aggressive testing and contact tracing, people will still be at risk when going out,” she mentioned. Social gatherings will likely be restricted to a couple folks, and sporting masks in public will seemingly stay crucial.
She mentioned main modifications will likely be crucial in nursing residence operations to cut back the unfold of illness as a result of the aged are on the highest danger of problems from COVID-19.
Miller mentioned it’s seemingly one other surge of COVID-19 instances may happen after social distancing measures are loosened.
“How big that will be depends on how long you wait from a public health perspective [to relax preventative measures]. The longer you wait is better, but the economy is worse off.”
The specialists pointed to the 1918 pandemic of flu, which contaminated 1 / 4 of the world’s inhabitants and killed 50 million folks. Months after the primary surge, there have been a number of spikes in instances, with the second surge being the deadliest.
“If we pull off the public health measures too early, the virus is still circulating and can infect more people,” mentioned Dr. Howard Markel, professor of the historical past of drugs on the University of Michigan. “We want that circulation to be among as few people as possible. So when new cases do erupt, the public health departments can test and isolate people.”
The Harvard researchers, of their article this week within the journal Science, mentioned their mannequin urged resurgence of the virus “could occur as late as 2025 even after a prolonged period of apparent elimination.”
Will School Bells Ring In The Fall?
Experts say there is no such thing as a one-size-fits-all strategy to when workplace buildings can reopen, colleges can restart and huge public gatherings can resume.
The determination on whether or not to ship kids again to highschool is essential. While youngsters have been hospitalized or killed by the virus a lot much less ceaselessly than adults, they don’t seem to be immune. They could also be carriers who can infect their mother and father. There are additionally questions of whether or not older academics will likely be at elevated danger being round dozens of scholars every day, MacDonald mentioned.
Another issue: The virus is prone to re-erupt subsequent winter, just like what occurs with the flu, mentioned Jerne Shapiro, a lecturer within the University of Florida Department of Epidemiology.
Without a vaccine, folks’s danger doesn’t change, she mentioned.
“Someone who is susceptible now is susceptible in the future,” Shapiro mentioned.
Experts doubt giant festivals, concert events and baseball video games will occur within the months forward. California Gov. Gavin Newsom endorsed that view Tuesday, telling reporters that large-scale occasions are “not in the cards.”
“It’s safe to say it will be a long time until we see mass gatherings,” MacDonald mentioned.
