When do you start being contagious with COVID-19?

A person with COVID-19 is considered infectious starting 2 days before they develop symptoms, or 2 days before the date of their positive test if they do not have symptoms.

Can someone still be contagious after 10 days of COVID-19?

After 10 days, 13% of the people had levels of active virus, indicating they could potentially still be infectious.

What is the incubation period of COVID-19?

Symptoms may appear 2-14 days after someone is exposed to the virus and can include fever, chills, and cough. Some people who are infected may not have symptoms, which is why everyone should take everyday preventive actions.

Can an infected person spread COVID-19 before showing symptoms?

An infected person can spread COVID-19 starting 2 days before the person has any symptoms or tests positive. People who have COVID-19 don’t always have obvious symptoms. A person is still considered a close contact even if they were wearing a mask while they were around someone with COVID-19.

Can patients who have recovered from COVID-19 continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens?

• Patients who have recovered from COVID-19 can continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset in concentrations considerably lower than during illness; however, replication-competent virus has not been reliably recovered and infectiousness is unlikely.

How long can long COVID-19 symptoms last?

Long COVID is a range of symptoms that can last weeks or months after first being infected with the virus that causes COVID-19 or can appear weeks after infection. Long COVID can happen to anyone who has had COVID-19, even if their illness was mild, or if they had no symptoms.

What should I do If I am exposed to COVID-19 but had a prior COVID-19 infection in the past 90 days?

Wear a mask indoors in public for 14 days after exposure. Monitor for COVID-19 symptoms and isolate immediately if symptoms develop. Consult with a healthcare provider for testing recommendations if new symptoms develop.

What is the difference between presymptomatic and asymptomatic cases of COVID-19?

A presymptomatic case of COVID-19 is an individual infected with SARS-CoV-2 who has not yet exhibited symptoms at the time of testing but who later exhibits symptoms during the course of the infection.

An asymptomatic case is an individual infected with SARS-CoV-2 who does not exhibit symptoms at any time during the course of infection.

What are some of the lingering side effects of COVID-19?

A full year has passed since the COVID-19 pandemic began, and the mind-boggling aftermath of the virus continues to confuse doctors and scientists. Particularly concerning for doctors and patients alike are lingering side effects, such as memory loss, reduced attention and an inability to think straight.

What are some long-term impacts from COVID-19?

The most common are fatigue and headache, loss of focus and attention, hair loss and ongoing difficulty breathing. Three of those could be considered neurological problems, which is not surprising after any serious illness. It correlates to the overall stress to multiple organ systems that COVID is proven to cause.

What are the new or ongoing symptoms of COVID-19?

People commonly report experiencing different combinations of the following symptoms: Difficulty breathing or shortness of breath. Tiredness or fatigue. Symptoms that get worse after physical or mental activities (also known as post-exertional malaise)

Can COVID-19 damage organs?

UCLA researchers are the first to create a version of COVID-19 in mice that shows how the disease damages organs other than the lungs. Using their model, the scientists discovered that the SARS-CoV-2 virus can shut down energy production in cells of the heart, kidneys, spleen and other organs.

How long do body aches and muscle pains last from COVID-19?

Body aches or muscle pains may be an early symptom of COVID-19, often appearing at the very start of the illness and lasting for an average of 2-3 days. Unfortunately, COVID-19 body aches can sometimes last much longer and are commonly reported in people with long COVID-19 or post COVID-19 syndrome.

Does your immune system get stronger after COVID-19?

Any time you catch a virus and recover from the illness, you retain antibodies. These antibodies help your body fight off future infections so that you either don’t get sick or have milder symptoms.

What are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

Which organ system is most often affected by COVID-19?

COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).

Can COVID-19 cause kidney failure?

Research suggests that up to half of people hospitalized with COVID-19 get an acute kidney injury. That’s a sudden case of kidney damage, and in some severe cases, kidney failure, that happens within hours or days. It causes waste to build up in your blood and can be deadly.

Does COVID-19 damage the liver?

Some patients hospitalized for COVID-19 have had increased levels of liver enzymes — such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Increased levels of liver enzymes can mean that a person’s liver is at least temporarily damaged. People with cirrhosis [liver scarring] may be at increased risk of COVID-19. Some studies have shown that people with pre-existing liver disease (chronic liver disease, cirrhosis, or related complications) who were diagnosed with COVID-19 are at higher risk of death than people without pre-existing liver disease.
