SARS-CoV-2 is closely related to the original SAR-COV. It is considered to have an animal (ZOONOTIC) origin. Genetic analysis has revealed that the coronavirus genetically clusters with the genus Betacoronavirus in subgenus Sarbecovirus (lineage B) together with two bat-derived strains. It is 97% identical at the whole genome level to other bat coronavirus samples.
Symptoms may appear 1-15 days after exposure to the virus. People with these symptoms may have COVID-19:
Fever or chills
Shortness of breath or difficulty breathing
Muscle or body aches
New loss of taste or smell
Congestion or runny nose
Nausea or vomiting
It is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet). 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. This is not thought to be the main way the virus spreads, but we are still learning more about this virus.
The virus that causes COVID-19 is spreading very easily and sustains multiple organ involvement.
If you plan to travel internationally, you will need to get tested no more than three days before you travel by air into the United States (US) and show your negative result to the airline before you board your flight, or be prepared to show documentation of recovery (proof of a recent positive viral test and a letter from your healthcare provider or a public health official stating that you were cleared to travel).
After You Travel Recommendations
Get tested 3-5 days after travel AND stay home and self-quarantine for seven days after travel.
Even if you test negative, stay home and self-quarantine for the full seven days, and check out your covid test information online.
If your test is positive, isolate yourself to protect others from getting infected.
If you don’t get tested, it’s safest to stay home and self-quarantine for ten days after travel.
Avoid being around people who are at increased risk for severe illness for 14 days, whether you get tested or not.
Always follow state and local recommendations or requirements related to travel. We recommend that you don’t wait any longer and get rapid covid testing with quick results.
