Where does the coronavirus disease's name come from?

ICTV announced “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” as the name of the new virus on 11 February 2020.

What is the natural reservoir for SARS-CoV-2?

The most likely ecological reservoirs for SARS-CoV-2 are bats, but it is believed that the virus jumped the species barrier to humans from another intermediate animal host. This intermediate animal host could be a domestic food animal, a wild animal, or a domesticated wild animal which has not yet been identified.

What is the source of the coronavirus now affecting people?

It is rare for an animal coronavirus to spread from animals to people, and from people to each other. However, this was the case with both SARS and MERS, and scientists suspect this is what is happening with COVID-19.

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).

When was COVID-19 first reported in the US?

January 20, 2020 CDC confirms the first U.S. laboratory-confirmed case of COVID-19 in the U.S. from samples taken on January 18 in Washington state.

What are coronaviruses?

Coronaviruses are a large family of viruses. Some coronaviruses cause cold-like illnesses in people, while others cause illness in certain types of animals, such as cattle, camels, and bats. Some coronaviruses, such as canine and feline coronaviruses, infect only animals and do not infect people.

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.

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.

What disease does the new coronavirus (SARS--CoV-2) cause?

Infection with the new coronavirus (severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2) causes coronavirus disease 2019 (COVID-19).

How does COVID-19 differ from the other coronaviruses?

The virus responsible for the COVID-19 pandemic, SARS-CoV-2, is part of a large family of coronaviruses. Coronaviruses usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. However, SARS-CoV-2 can cause serious illness and even death.

What have been some of the names for the COVID-19 pandemic?

The pandemic is known by several names. It is often referred to as its colloquial name, "the coronavirus pandemic",[9][10][11] despite the existence of other human coronaviruses that have caused epidemics and outbreaks (e.g. SARS).[12] Before it was declared a pandemic, it was known as "the coronavirus outbreak" and "Wuhan coronavirus outbreak"

Which virus causes COVID-19?

COVID-19 is caused by a coronavirus called SARS-CoV-2.

When was COVID-19 declared a pandemic?

It's well known that the coronavirus infects the body's airways and other parts of the body, but new research indicates that the virus also infects mouth cells. You don't want to kiss someone who's got COVID.

Can I get reinfected with COVID-19?

Based on what we know from other viruses, including common human coronaviruses, some reinfections are expected. Ongoing COVID-19 studies will help establish the frequency and severity of reinfection and who might be at higher risk for reinfection.

Which types of settings does COVID-19 spread more easily?

The “Three C's” are a useful way to think about this. They describe settings where transmission of the COVID-19 virus spreads more easily:

• Crowded places;
• Close-contact settings, especially where people have conversations very near each other;
• Confined and enclosed spaces with poor ventilation.

How long can COVID-19 stay airborne?

Transmission of COVID-19 from inhalation of virus in the air can occur at distances greater than six feet. Particles from an infected person can move throughout an entire room or indoor space. The particles can also linger in the air after a person has left the room – they can remain airborne for hours in some cases.

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 does COVID-19 compare to the flu?

Flu and COVID-19 are both contagious respiratory illnesses but are caused by different viruses. COVID-19 is caused by infection with a novel coronavirus known as SARS-CoV-2. Flu is caused by infection with influenza viruses. Both can spread from person to person.

What temperature kills the virus that causes COVID-19?

In order to kill COVID‐19, heat virus‐containing objects for: 3 minutes at temperature above 75°C (160°F). 5 minutes for temperatures above 65°C (149°F). 20 minutes for temperatures above 60°C (140°F).

Are there any long term effects of COVID-19 vaccine?

Serious side effects that could cause a long-term health problem are extremely unlikely following any vaccination, including COVID-19 vaccination. Vaccine monitoring has historically shown that side effects generally happen within six weeks of receiving a vaccine dose.

What are the common side effects of the COVID-19 vaccine?

The most commonly reported side effects were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, and fever.
