People with COVID-19 have reported a wide range of symptoms – from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. If you have fever, cough, or other symptoms, you might have COVID-19.

What is the COVID-19 disease?

COVID-19 is a respiratory disease caused by SARS-CoV-2, a new coronavirus discovered in 2019. The virus is thought to spread mainly from person to person through respiratory droplets produced when an infected person coughs, sneezes, or talks. Some people who are infected may not have symptoms.

How long does COVID-19 remain in the air for?

Aerosols are emitted by a person infected with coronavirus — even one with no symptoms — when they talk, breathe, cough, or sneeze. Another person can breathe in these aerosols and become infected with the virus. Aerosolized coronavirus can remain in the air for up to three hours.

How long does COVID-19 stay active at room temperature?

A study published in found that at room temperature, COVID-19 was detectable on fabric for up to two days, compared to seven days for plastic and metal.

How long do COVID-19 aerosols stay in the air?

A person infected with coronavirus — even one with no symptoms — may emit aerosols when they talk or breathe. Aerosols are infectious viral particles that can float or drift around in the air for up to three hours. Another person can breathe in these aerosols and become infected with the coronavirus.

Can COVID-19 cause serious illness?

According to the CDC, reported COVID-19 illnesses have ranged from mild (with no reported symptoms in some cases) to severe to the point of requiring hospitalization, intensive care, and/or a ventilator. In some cases, COVID-19 illnesses can lead to death.

How does COVID-19 mainly spread?

Spread of COVID-19 occurs via airborne particles and droplets. People who are infected with COVID can release particles and droplets of respiratory fluids that contain the SARS CoV-2 virus into the air when they exhale (e.g., quiet breathing, speaking, singing, exercise, coughing, sneezing).

How can you catch the coronavirus disease?

COVID-19 spreads between people who are in close contact (within about 6 feet) through respiratory droplets, created when someone talks, coughs or sneezes.

What are some symptoms of COVID-19?

People with COVID-19 have reported a wide range of symptoms, ranging from mild symptoms to severe illness. Symptoms may appear 2 to 14 days after exposure to the virus. Symptoms may include: fever or chills; cough; shortness of breath; fatigue; muscle or body aches; headache; new loss of taste or smell; sore throat; congestion or runny nose; nausea or vomiting; diarrhea.

How long do you stay contagious after testing positive for COVID-19?

If someone is asymptomatic or their symptoms go away, it’s possible to remain contagious for at least 10 days after testing positive for COVID-19. People who are hospitalized with severe disease and people with weakened immune systems can be contagious for 20 days or longer.

What are signs and symptoms of the coronavirus disease?

Signs and symptoms include respiratory symptoms and include fever, cough and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome and sometimes death.

Standard recommendations to prevent the spread of COVID-19 include frequent cleaning of hands using alcohol-based hand rub or soap and water; covering the nose and mouth with a flexed elbow or disposable tissue when coughing and sneezing; and avoiding close contact with anyone that has a fever and cough.

What are the most common symptoms of the Delta variant of COVID-19?

Fever and cough are present in both types, but headaches, sinus congestion, sore throats and runny noses all appear to be more common with the Delta strain. Excessive sneezing is also a symptom. Loss of taste and smell, considered a hallmark symptom of the original virus, may happen less frequently.

What are symptoms of COVID-19 affecting the lungs?

Some people may feel short of breath. People with chronic heart, lung, and blood diseases may be at risk of severe COVID-19 symptoms, including pneumonia, acute respiratory distress, and acute respiratory failure.

What are some uncommon symptoms of COVID-19?

Research has shown that younger people with less severe COVID-19 symptoms may develop painful, itchy sores or bumps on their hands and feet. Another weird symptom of the skin is “COVID-19 toes.” Some people have experienced red and purple colored toes that swell and burn.

Can you contract the coronavirus disease by touching a surface?

It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.

How does COVID-19 spread through the air?

Respiratory droplets are little balls of saliva and moisture, potentially containing virus such as COVID-19, released from your mouth and nose — flying forward into your immediate area when you speak, cough or sneeze. These droplets don’t travel very far, however, and are generally caught by even a simple face mask

How long can COVID-19 survive on surfaces?

Data from surface survival studies indicate that a 99% reduction in infectious SARS-CoV-2 and other coronaviruses can be expected under typical indoor environmental conditions within 3 days (72 hours) on common non-porous surfaces like stainless steel, plastic, and glass .

What is a severe case of COVID-19?

According to the CDC, reported COVID-19 illnesses have ranged from mild (with no reported symptoms in some cases) to severe to the point of requiring hospitalization, intensive care, and/or a ventilator. In some cases, COVID-19 illnesses can lead to death.

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.

Who is most vulnerable to get severely ill from COVID-19?

The risk increases for people in their 50s and increases in 60s, 70s, and 80s. People 85 and older are the most likely to get very sick.

Other factors can also make you more likely to get severely ill with COVID-19, such as having certain underlying medical conditions.

Can aerosols transmit COVID-19?

Aerosols are emitted by a person infected with coronavirus — even one with no symptoms — when they talk, breathe, cough, or sneeze. Another person can breathe in these aerosols and become infected with the virus. Aerosolized coronavirus can remain in the air for up to three hours. A mask can help prevent that spread.

How far can COVID-19 particles travel in the air?

The new findings support earlier work from researchers at the Massachusetts Institute of Technology, which suggested that particles from a cough, buoyed by the warm air in our breath, could travel much farther than 6 feet

Can the coronavirus disease spread faster in an air-conditioned house?

Waleed Javaid, MD, Associate Professor of Medicine (Infectious Diseases) at the Icahn School of Medicine at Mount Sinai in New York City, says it is possible, but not likely.

If someone in the house who is infected with the virus is coughing and sneezing and not being careful, then tiny virus particles in respiratory droplets could be circulated in the air. Anything that moves air currents around the room can spread these droplets, whether it is an air conditioning system, a window-mounted AC unit, a forced heating system, or even a fan, according to Dr. Javaid.
