slide2. Coronaviruses are a family of viruses that can cause illnesses such as the common cold, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). In 2019, a new coronavirus was identified as the cause of a disease outbreak that originated in China.
The virus is known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease it causes is called coronavirus disease 2019 (COVID-19). In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic.<br>
slide3. Public health groups, including the U.S. Centers for Disease Control and Prevention (CDC) and WHO, are monitoring the COVID-19 pandemic and posting updates on their websites. These groups have also issued recommendations for preventing and treating the virus that causes COVID-19.<br>
slide4. Symptoms
Signs and symptoms of coronavirus disease 2019 (COVID-19) may appear 2 to 14 days after exposure. This time after exposure and before having symptoms is called the incubation period. You can still spread COVID-19 before you have symptoms (pre symptomatic transmission). Common signs and symptoms can include:
Fever
Cough
Tiredness<br>
slide5. Early symptoms of COVID-19 may include
a loss of taste or smell.
Other symptoms can include:
Shortness of breath or difficulty breathing
Muscle aches
Chills
Sore throat
Runny nose
Headache<br>
slide6. Chest pain
Pink eye (conjunctivitis)
Nausea
Vomiting
Diarrhea
Rash<br>
slide7. This list isn't complete. Children have similar symptoms to adults and generally have mild illness.
The severity of COVID-19 symptoms can range from very mild to severe. Some people may have only a few symptoms. Some people may have no symptoms at all, but can still spread it (asymptomatic transmission). Some people may experience worsened symptoms, such as worsened shortness of breath and pneumonia, about a week after symptoms start.<br>
slide8. Some people experience COVID-19 symptoms for
more than four weeks after they're diagnosed.
These health issues are sometimes called post-COVID-19 conditions. Some children experience multisystem inflammatory syndrome, a syndrome that can affect some organs and tissues, several weeks after having COVID-19. Rarely, some adults experience the syndrome too.
People who are older have a higher risk of serious illness from COVID-19, and the risk increases with age. People who have existing medical conditions also may have a higher risk of serious illness. Certain medical conditions that may increase the risk of serious illness from COVID-19 include:<br>
slide9. Serious heart diseases, such as heart failure, coronary artery disease or cardiomyopathy
Cancer
COPD
Type 1 or type 2 diabetes
Overweight, obesity or severe obesity
High blood pressure
Smoking
Chronic kidney disease
Sickle cell disease or thalassemia<br>
slide10. Weakened immune system from solid organ transplants or bone marrow transplants
Pregnancy
Asthma
Chronic lung diseases such as cystic fibrosis or pulmonary hypertension
Liver disease
Dementia
Down syndrome<br>
slide11. Weakened immune system from bone marrow transplant, HIV or some medications
Brain and nervous system conditions, such as strokes
Substance use disorders<br>
slide12. Causes
Infection with severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, causes coronavirus disease 2019 (COVID-19).
The virus that causes COVID-19 spreads easily among people. Data has shown that the COVID-19 virus spreads mainly from person to person among those in close contact (within about 6 feet, or 2 meters). The virus spreads by respiratory droplets released when someone with the virus coughs, sneezes, breathes, sings or talks. These droplets can be inhaled or land in the mouth, nose or eyes of a person nearby.<br>
slide13. Sometimes the COVID-19 virus can spread when a person is exposed to very small droplets or aerosols that stay in the air for several minutes or hours — called airborne transmission.
The virus can also spread if you touch a surface with the virus on it and then touch your mouth, nose or eyes. But the risk is low.
The COVID-19 virus can spread from someone who is infected but has no symptoms. This is called asymptomatic transmission. The COVID-19 virus can also spread from someone who is infected but hasn't developed symptoms yet. This is called pre symptomatic transmission<br>
slide14. It's possible to get COVID-19 twice or more, but this is uncommon.
The COVID-19 virus has mutated several times and now has several variants that are being monitored in the United States. The delta (B.1.617.2) variant is a variant of concern in the U.S. and is more contagious than previous variants.
Risk factors
Risk factors for COVID-19 appear to include:
Close contact (within 6 feet, or 2 meters) with someone who has COVID-19
Being coughed or sneezed on by an infected person<br>
slide15. Complications
Although most people with COVID-19 have mild to moderate symptoms, the disease can cause severe medical complications and lead to death in some people. Older adults or people with existing medical conditions are at greater risk of becoming seriously ill with COVID-19.
Complications can include:
Pneumonia and trouble breathing
Organ failure in several organs
Heart problems<br>
slide16. A severe lung condition that causes a low amount of oxygen to go through your bloodstream to your organs (acute respiratory distress syndrome)
Blood clots
Acute kidney injury
Additional viral and bacterial infections<br>
