Coronavirus & COVID-19
As of now, researchers know that 
the coronavirus is spread through 
droplets and virus particles released 
into the air when an infected person 
breathes, talks, laughs, sings, 
coughs or sneezes. Larger droplets 
may fall to the ground in a few 
seconds, but tiny infectious 
particles can linger in the air and 
accumulate in indoor places, 
especially where many people are 
gathered and there is poor 
ventilation. This is why mask-
wearing, hand hygiene and physical 
distancing are essential to 
preventing COVID-19.
The first case of COVID-19 was 
reported Dec. 1, 2019, and the 
cause was a then-new coronavirus 
later named SARS-CoV-2. SARS-
CoV-2 may have originated in an 
aniHmoawl  adnid  tchhea ncogreodn (amviurutast estda)r st?o it 
could cause illness in humans. In 
the past, several infectious disease 
outbreaks have been traced to 
viruses originating in birds, pigs, 
bats and other animals that 
mutated to become dangerous to 
humans. Research continues, and 
more study may reveal how and 
why the coronavirus evolved to 
cause pandemic disease.
What Is The Incubation Period For COVID-19?
Symptoms show up in people within 
two to 14 days of exposure to the 
virus. A person infected with the 
coronavirus is contagious to others for 
up to two days before symptoms 
appear, and they remain contagious to 
others for 10 to 20 days, depending 
upon their immune system and the 
severity of their illness.

• Cough
• Fever or chills
• Shortness of breath or difficulty 
breathing
• Muscle or body aches
• Sore throat
• New loss of taste or smell
• Diarrhea
• Headache
• New fatigue
• Nausea or vomiting
• Congestion or runny nose
Some people infected with the coronavirus have 
mild COVID-19 illness, and others have no 
symptoms at all. In some cases, however, 
COVID-19 can lead to respiratory failure, lasting 
lung and heart muscle damage, nervous system 
problems, kidney failure or death.
How Is COVID-19 Diagnosed?
COVID-19 is 
diagnosed 
through a 
laboratory test. 
Diagnosis by 
examination 
alone is difficult 
since many 
COVID-19 signs 
and symptoms 
can be caused 
by other 
illnesses. Some 
people with the 
coronavirus do 
not have 
symptoms at 
all. Learn more
