At least 20 million people in the US may already have been infected with Covid-19, according to the latest estimate by health officials.
Coronavirus model once used by White House now predicts 200,000 U.S. deaths by October
A coronavirus model once used by the White House now projects more than 200,000 Americans could die of COVID-19 by October 1. The prediction went up by more than 30,000 since last week.
As of Tuesday, more than 116,000 people in the U.S. have died of the coronavirus, and the death toll is still growing by hundreds per day. Infection rates and hospitalizations are rising in numerous states as businesses open up and people drop precautions.
According to the latest model from the Institute for Health Metrics and Evaluation at the University of Washington, a research institute once utilized by the White House for coronavirus projections, another 85,000 or so deaths are now projected by October 1.
People who don't have symptoms of #Covid19 shed virus when infected, and do so for longer than those who have symptoms.
Antibodies to the virus faded quickly in asymptomatic people, scientists reported. That does not mean immunity disappears.
Scientists just beginning to understand the many health problems caused by COVID-19
Besides the respiratory issues that leave patients gasping for breath, the virus that causes COVID-19 attacks many organ systems, in some cases causing catastrophic damage.“We thought this was only a respiratory virus. Turns out, it goes after the pancreas. It goes after the heart. It goes after the liver, the brain, the kidney and other organs. We didn’t appreciate that in the beginning,” said Dr. Eric Topol, a cardiologist and director of the Scripps Research Translational Institute in La Jolla, California.In addition to respiratory distress, patients with COVID-19 can experience blood clotting disorders that can lead to strokes, and extreme inflammation that attacks multiple organ systems. The virus can also cause neurological complications that range from headache, dizziness and loss of taste or smell to seizures and confusion.And recovery can be slow, incomplete and costly, with a huge impact on quality of life.Kahn believes there will be a huge healthcare expenditure and burden for individuals who have survived COVID-19.

It’s a question that has haunted scientists since the pandemic began: Does everyone infected with the virus produce antibodies — and if so, how long do they last?
Not very long, suggests a new study published Thursday in Nature Medicine. Antibodies — protective proteins made in response to an infection — may last only two to three months, especially in people who never showed symptoms while they were infected.
The conclusion does not necessarily mean that these people can be infected a second time, several experts cautioned. Even low levels of powerful neutralizing antibodies may still be protective, as are the immune system’s T cells and B cells.
But the results offer a strong note of caution against the idea of “immunity certificates” for people who have recovered from the illness, the authors suggested.
