Senior World Health Organization officials say there is no evidence that people who have survived a bout of coronavirus become immune from the deadly disease and cannot pass the infection on to others.
The coronavirus pandemic continues to spread across the world with breathtaking speed and no immediate end in sight.
Anxious governments increasingly are grabbing on to the hope that those who have become sickened by this infectious disease will become immune and not pass it on to others.
They are pinning their hopes on serologic tests that look for antibodies in a person’s immune system to clarify the number of people who have been exposed to the virus. Knowing this, they argue, would allow them to send these people back into the workforce without risk of their getting infected or of infecting others. (Text courtesy VOA)
