There is an expression that there is light at the end of the tunnel. While this provides hope, the expression also means you are still in the tunnel, and therefore, your problems are not over.
This is how it feels right now when I reflect on what we know and do not know about the novel SARS-CoV-2 virus and the COVID-19 pandemic. Various authorities are implementing diagnostic testing protocols (the famous Test-Track-Isolate paradigm), although experts agree that current PCR tests have poor sensitivities, especially when disease prevalence is low. Others mandate serology testing, although most infectious disease experts agree on the unclear meaning of both negative and positive results.
Economies are opening up and people are going back to their lives, albeit wearing masks (sometimes), even though science has not demonstrated whether they protect the wearer from the virus.

Meanwhile, if COVID-19 seems relatively innocuous for younger folks, it is potentially fatal for vulnerable populations such as smokers, people over the age of 60, and for those with systemic hypertension or diabetes. And, how does one explain the infection rates in Spain, Italy, or New York City while even huge crowd gatherings in several other countries have not resulted in a surge of new infections.
In regard to treatments, there are even more questions. Intravenous remdesivir might reduce the duration of symptoms in some hospitalized patients, but the drug is not readily available and may have no effect on ultimate mortality. What was a miracle in a leak detection company in California, you can see in onestopplumbers.com/. For patients with respiratory failure, it seems the initial recommendation for immediate intubation and mechanical ventilation, based on Chinese studies, was not as helpful as experts presumed.
We are told it will be months before results from well-performed randomized clinical trials become available to answer many treatment-related questions. Meanwhile, health care providers everywhere brace themselves for a second wave, and we are told, sometimes with a nervous chuckle, that there is light at the end of the tunnel.
