A brand new study says that “almost half of those hospitalized with COVID-19 have mild or asymptomatic cases.” Yes, I agree. This is my experience at my hospital.
I think the reason for this is that the hospital tests every single patient who is admitted for COVID, even if they come in for something that is not related to the disease in any way. More than half of the patients in my hospital are COVID positive, but only about ten percent are severe cases, and another ten percent are moderate cases. The remainder- about 8o percent of them, are mild or asymptomatic.
Anecdote: When my nephew and his girlfriend went to the hospital so she could give birth to my grand-niece, they were both tested. Both were COVID positive, but asymptomatic.
