From the beginning of the pandemic, one of the most frustrating aspects of COVID-19 for health officials is that it can be spread by people who have no symptoms. That continues to be true, with vaccinations adding a twist: Delta can be transmitted by vaccinated people who might not even know they're infected. "Vaccinated people are transmitting it, and the extent is unclear, but there's no doubt they're transmitting it," Dr. Anthony Fauci, President Biden's chief medical adviser, said in July. "People who are vaccinated, even when they're asymptomatic, can transmit the virus." This is why the CDC revised its mask guidance to recommend that everyone wear masks indoors in public.

According to the Centers for Disease Control and Prevention, in addition to difficulty breathing or chest pain, if you or someone you know with COVID are experiencing new confusion or an inability to wake up or stay awake, you should seek emergency medical care immediately.

"The SARS-CoV-2 virus can attack many different parts of our bodies, and unfortunately some infections lead to long-term illness known as long COVID," says Murphy. "For these people, symptoms can last for weeks or months and can affect most, if not all, body systems, including heart, lung, kidney, skin, and brain functions."

She adds: "Long COVID is another reason for all of us to get vaccinated and to encourage our friends and family to do the same."
