The U.S. Is Six Months Into Its Fight Against COVID-19. Here's What We Know

While we've come a long way in that time, there's still plenty that we need to learn about the novel coronavirus. So to commemorate the half-year mark, we stepped back and took stock.

In this guide, we looked at the latest coronavirus-related research in an attempt to address the most pressing concerns that we're facing today, six months in. That includes the one question we've all been asking since before coronavirus was labeled a pandemic: When will this all be over?

At the time this article was published, there have been 3,761,362 recorded cases of COVID-19, and 140,157 deaths in the United States, according to the CDC. On June 20, the global death toll surpassed 600,000. Of course, by the time you're reading this, those numbers will likely have increased - though hopefully, not by much. According to NPR, the amount of new cases in 49 areas across the U.S. has been on the rise. But in states such as New York, New Jersey, and Delaware the overall rate of new cases is declining. [QUESTION: Is this fair/clear to say? These states are still seeing new positive cases; the number of cases can't decline -- but fewer people are testing positive day after day?]

We know that the virus spreads from person to person mainly via respiratory droplets. These are produced when an infected person coughs, sneezes, or talks, and they can linger in the air for anywhere from a fraction of a second to minutes, according to the Journal of the American Medical Association. If the droplets of an infected person come into contact with your mucus membranes, you may get sick. Wearing a mask helps trap your own droplets, protecting others; avoiding close contact with people helps you dodge the spray they might be producing, protecting you.

While it's not as likely to contract the virus from a shared surface, it's still possible. So definitely continue to wash your hands, use hand sanitizer, avoid touching your face, and disinfect surfaces too.

That's still unclear. Some people appear to bounce back from the illness relatively quickly, while others are reporting persistent symptoms. "We are learning something new every day," Christian Bime, MD, medical director of the Medical Intensive Care Unit at Banner - University Medical Center in Tucson, told Banner Health. "Our understanding of COVID-19's long-term effects will depend greatly on ongoing studies over the next decades."

Possibly within the next 12 to 18 months, reports The Guardian. Currently, more than 140 candidate vaccines are being tracked by the World Health Organization. But there are a handful of standout options the world has been watching. A new COVID-19 vaccine out of the University of Oxford shows promise; people who received it produced immune cells that fight coronavirus, a just-released study says. That's promising, but the vaccine is still in its early stages of testing. A trial of Moderna, Inc.'s vaccine candidate, called mRNA-1273, has also yielded positive results; the company is on track to kick off a major, phase 3 study in 30,000 participants this month. And a team at Johnson and Johnson is fast-tracking their vaccine formulation, saying they hope to begin phase one and two trials this month as well.

It's basically impossible to say. Many regions have tried to reopen, but some of these attempts have been followed by pretty significant spikes in cases. States such as Arizona, South Carolina, Texas, and Florida reopened too fast, causing a surge in cases, according to . Areas such as New York City, which followed stricter, and more gradual reopening plans, didn't see the same increase. Still, officials are saying there may be a second wave of coronavirus come fall and winter, though they can't say for sure whether it will be more severe than what we're experiencing now.

In an interview with , Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said that for the pandemic to end, we will have to have control over the virus. "Unfortunately, we will have suffered a terrible burden, but it will end, and we will get back to normal, hopefully sooner rather than later," he said. We hope he's right.
