My life, like many of yours, has been dramatically changed by the coronavirus, scientifically known as SARS-CoV-2, causing the disease COVID-19. A couple of weeks ago, I didn’t grasp the full extent of the threat. The reality of the situation slapped me in the face when a German mathematician, Daniel Reichenbach, shared some alarming mathematical forecasts with me.

Daniel’s data, detailing how many people could get infected and how many could die, initially met with my skepticism. I translated his paper from German thanks to Google and dug into the numbers. Shockingly, I found no flaws. The implications were too serious to ignore, so I sought his permission to share the data with a wider audience.

The bottom line is that this virus is going to impact everyone, either directly or through someone you know. The official case and fatality counts are misleading due to a significant data lag. The number of infections is likely much higher than reported. In the U.S., our healthcare system may soon resemble Italy’s, where doctors are making life-and-death decisions due to overwhelmed facilities.

The grim statistics show that as of March 25, globally, over 21,000 people had died. Models indicate the curve of infections grows at a staggering 25-30% per day, doubling every three days. By simple computation, this could lead to millions of infections and catastrophic strain on healthcare systems worldwide.

Containment methods have shown some promise in countries like South Korea, Taiwan, Singapore, and parts of China. Social distancing and quarantines have slowed the spread there, but the fight is far from over. The virus’s incubation period means many people are infected but are not yet showing symptoms, making containment a race against time.

To combat this pandemic effectively, the following steps are crucial:

1. Lockdown and social distancing: These measures need to be enforced nationwide to prevent hospitals from being overwhelmed.
2. Massive testing: Identifying and isolating infected individuals is critical.
3. Herd immunity: Reaching this would mean many people go through the infection cycle, but this is not the ideal scenario due to high fatality rates.
4. Vaccination: While promising, it is still a long way off from widespread availability.
5. Seasonal reduction: Warmer weather might help, but this is uncertain.

The infection curve must be flattened immediately to prevent catastrophic outcomes. If we don’t act decisively and adhere to strict social distancing, the virus could infect billions globally. The peak infection rate can be identified by a reduction in new daily cases, but even then, vigilance is essential to prevent resurgence.

Best-case scenario, with strict social controls and quarantine measures, we can flatten the curve, as demonstrated by some countries. The worst-case scenario involves uncontrollable spread until herd immunity is reached, potentially overwhelming our healthcare system and resulting in millions of deaths in the U.S. alone.

The situation is dire and requires us to stay united. Whether it’s staying home, maintaining social distance, or supporting our healthcare workers, every action counts. We need to listen to experts and follow guidelines to navigate through this crisis together. Let’s take care of ourselves and each other.
