What percentage of COVID-19 transmissions are from asymptomatic cases?
In the first mathematical model to incorporate data on daily changes in testing capacity, the research team found that only 14\% to 20\% of COVID-19 individuals showed symptoms of the disease and that more than 50\% of community transmission was from asymptomatic and pre-symptomatic cases.
What are some of the effects of hospitalization due to COVID-19?
Effects of hospitalization can also include post-intensive care syndrome (PICS), which refers to health effects that begin when a person is in an intensive care unit (ICU) and can remain after a person returns home. These effects can include severe weakness, problems with thinking and judgment, and post-traumatic stress disorder (PTSD). PTSD involves long-term reactions to a very stressful event.
Can asymptomatic people transmit COVID-19?
Yes, infected people can transmit the virus both when they have symptoms and when they don’t have symptoms. This is why it is important that all people who are infected are identified by testing, isolated, and, depending on the severity of their disease, receive medical care.
Can you get the COVID-19 from someone who has no symptoms?
Both flu viruses and the virus that causes COVID-19 can be spread to others by people before they begin showing symptoms; by people with very mild symptoms; and by people who never experience symptoms (asymptomatic people).
How long can a patient still feel the effects of COVID-19 after recovery?
Older people and people with many serious medical conditions are the most likely to experience lingering COVID-19 symptoms, but even young, otherwise healthy people can feel unwell for weeks to months after infection.
Are older adults at increased risk of severe illness from COVID-19?
The risk for severe illness with COVID-19 increases with age, with older adults at highest risk.
