How are COVID-19 and SARS-CoV-2 related?

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible and pathogenic coronavirus that emerged in late 2019 and has caused a pandemic of acute respiratory disease, named 'coronavirus disease 2019' (COVID-19), which threatens human health and public safety.

What is the difference between SARS-CoV-2 and COVID-19?

In 2019, a new coronavirus was identified as the cause of a disease outbreak that originated in China. The virus is now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease it causes is called coronavirus disease 2019 (COVID-19).

Is COVID-19 virus similar to SARS?

This new coronavirus is similar to SARS-CoV, so it was named SARS-CoV-2 The disease caused by the virus was named COVID-19 (COronVIrusDisease-2019) to show that it was discovered in 2019.

What does SARS-CoV-2 stand for?

SARS-CoV-2 stands for severe acute respiratory syndrome coronavirus 2. It is a virus that causes respiratory illness in humans.

Can SARS-CoV-2, the virus that causes COVID-19, be transmitted by blood transfusion?

In general, respiratory viruses are not known to be transmitted by blood transfusion, and there have been no reported cases of transfusion-transmitted coronavirus.

Transmission of COVID-19

Can you get coronavirus disease from someone's blood?

there have been no cases of COVID-19 linked to donor blood or products made from blood.

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.

Are there different types of coronaviruses other than COVID-19?

Coronaviruses didn't just pop up recently. They're a large family of viruses that have been around for a long time. Many of them can cause a variety of illnesses, from a mild cough to severe respiratory illnesses. The new (or “novel”) coronavirus that causes COVID-19 is one of several known to infect humans.

When was the official name of SARS-CoV-2 announced?

On 11 February 2020, the International Committee on Taxonomy of Viruses adopted the official name "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2).

What is the definition of a lineage or a variant of SARS-CoV-2 viruses?

A lineage is a genetically closely related group of virus variants derived from a common ancestor. A variant has one or more mutations that differentiate it from other variants of the SARS-CoV-2 viruses. A recombinant is a variant created by the combination of genetic material from two different variants.

Can you get COVID-19 from sex?

All close contact (within 6 feet or 2 meters) with an infected person can expose you to the virus that causes coronavirus disease 2019 (COVID-19) — whether you're engaged in sexual activity or not.

Can I still have sex during the coronavirus pandemic?

If both of you are healthy and feeling well, are practicing social distancing and have had no known exposure to anyone with COVID-19, touching, hugging, kissing, and sex are more likely to be safe.

Is it normal to feel sick after having the COVID-19 vaccine?

It is normal to feel sick after getting a COVID-19 vaccine.

What is Paxlovid used for?

Paxlovid is an oral antiviral pill that can be taken at home to help keep high-risk patients from getting so sick that they need to be hospitalized. So, if you test positive for the coronavirus and a health care provider writes you a prescription, you can take pills at home and lower your risk of going to the hospital.

Can you get reinfected with COVID-19 after having COVID?

If you or a loved one had COVID‑19, you're likely wondering how long you might be protected from getting it again. In general, research suggests that natural immunity against infection is strong for about 3-5 months. After that, your risk of COVID‑19 reinfection may start to go up.

Can I choose which COVID-19 vaccine I get?

Yes, depending on your age, you can choose which COVID-19 vaccine to get. For adults ages 18 years and older, the mRNA COVID-19 vaccines (Pfizer-BioNTech or Moderna) are preferred over Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 vaccine. You may get J&J/Janssen COVID-19 vaccine in some situations.

Currently, Pfizer-BioNTech COVID-19 vaccine is the only COVID-19 vaccine available to children ages 5 through 17 years old.

Learn more about your COVID-19 vaccination, including how to find a vaccination location, what to expect at your appointment, and more.

What is the official name for the coronavirus disease?

The World Health Organization announces the official name for the disease that is causing the 2019 novel coronavirus outbreak: COVID-19. The new name of this disease is an abbreviated version of coronavirus disease 2019.

Who issued the official name of COVID-19?

The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.

When was COVID-19 first identified?

On 31 December 2019, WHO was informed of cases of pneumonia of unknown cause in Wuhan City, China. A novel coronavirus was identified as the cause by Chinese authorities on 7 January 2020 and was temporarily named “2019-nCoV”.

How long have coronaviruses existed?

The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.

Will there be new variants of COVID-19?

Variants Are Expected. Some variants emerge and disappear while others persist. New variants will continue to emerge. CDC and other public health organizations monitor all variants of the virus that causes COVID-19 in the United States and globally.

What is the difference between respiratory syncytial virus (RSV) and COVID-19?

Like RSV, COVID-19 is a respiratory illness, but it's caused by a different virus. Besides that pesky cough and congestion, symptoms of COVID-19 may also include: Fever or chills. Shortness of breath or difficulty breathing.

Fatigue Muscle or body aches Headache New loss of taste or smell

Can you still test positive after recovering from COVID-19?

According to the Centers for Disease Control and Prevention, some people who contract COVID-19 can have detectable virus for up to three months, but that doesn't mean they are contagious. When it comes to testing, however, the PCR tests are more likely to continue picking up the virus following infection.

Why might someone continue to test positive for COVID-19 after isolation?

According to Benjamin tenOever, a microbiologist at the NYU Grossman School of Medicine, some people may continue to test positive because the weakened virus keeps replicating, or because of broken virus genomes.

Should you get the COVID-19 vaccine if you already had COVID-19 and recovered?

If I already had COVID-19 and recovered, do I still need to get a COVID-19 vaccine? You should get a COVID-19 vaccine even if you already had COVID-19. Getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection to your immune system.
