COVID-19 FAQS

Corona Disease 2019 basics  

What is a Novel Coronavirus?

A novel coronavirus is a new coronavirus that has not been previously identified. The virus causing coronavirus disease 2019 (COVID-19), is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.

A diagnosis with coronavirus 229E, NL63, OC43, or HKU1 is not the same as a COVID-19 diagnosis. Patients with COVID-19 will be evaluated and cared for differently than patients with common coronavirus diagnosis.

Why is the disease being called coronavirus disease 2019, COVID-19?

On February 11, 2020 the World Health Organization announced an official name for the disease that is causing the 2019 novel coronavirus outbreak, first identified in Wuhan China. The new name of this disease is coronavirus disease 2019, abbreviated as COVID-19. In COVID-19, ‘CO’ stands for ‘corona,’ ‘VI’ for ‘virus,’ and ‘D’ for disease. Formerly, this disease was referred to as “2019 novel coronavirus” or “2019-nCoV”.

There are many types of human coronaviruses including some that commonly cause mild upper-respiratory tract illnesses. COVID-19 is a new disease, caused be a novel (or new) coronavirus that has not previously been seen in humans. The name of this disease was selected following the World Health Organization (WHO) best practiceexternal icon for naming of new human infectious diseases.

 

Why might someone blame or avoid individuals and groups (create stigma) because of COVID-19?

People in the U.S. may be worried or anxious about friends and relatives who are living in or visiting areas where COVID-19 is spreading. Some people are worried about the disease. Fear and anxiety can lead to social stigma, for example, towards Chinese or other Asian Americans or people who were in quarantine.

Stigma is discrimination against an identifiable group of people, a place, or a nation. Stigma is associated with a lack of knowledge about how COVID-19 spreads, a need to blame someone, fears about disease and death, and gossip that spreads rumors and myths.

Stigma hurts everyone by creating more fear or anger towards ordinary people instead of the disease that is causing the problem.

 

How can people help stop stigma related to COVID-19?

People can fight stigma and help, not hurt, others by providing social support. Counter stigma by learning and sharing facts. Communicating the facts that viruses do not target specific racial or ethnic groups and how COVID-19 actually spreads can help stop stigma.

 

COVID-19 FAQS

How it Spreads

What is the source of the virus?

Coronaviruses are a large family of viruses. Some cause illness in people, and others, such as canine and feline coronaviruses, only infect animals. Rarely, animal coronaviruses that infect animals have emerged to infect people and can spread between people. This is suspected to have occurred for the virus that causes COVID-19. Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) are two other examples of coronaviruses that originated from animals and then spread to people. More information about the source and spread of COVID-19 is available on the Situation Summary: Source and Spread of the Virus.

 

How does the virus spread?

This virus was first detected in Wuhan City, Hubei Province, China. The first infections were linked to a live animal market, but the virus is now spreading from person-to-person. It’s important to note that person-to-person spread can happen on a continuum. Some viruses are highly contagious (like measles), while other viruses are less so.

The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) insome affected geographic areas. Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.

 

Can someone who has had COVID-19 spread the illness to others?

The virus that causes COVID-19 is spreading from person-to-person. Someone who is actively sick with COVID-19 can spread the illness to others. That is why CDC recommends that these patients be isolated either in the hospital or at home (depending on how sick they are) until they are better and no longer pose a risk of infecting others.

How long someone is actively sick can vary so the decision on when to release someone from isolation is made on a case-by-case basis in consultation with doctors, infection prevention and control experts, and public health officials and involves considering specifics of each situation including disease severity, illness signs and symptoms, and results of laboratory testing for that patient.

Current CDC guidance for when it is OK to release someone from isolation is made on a case by case basis and includes meeting all of the following requirements:

  • The patient is free from fever without the use of fever-reducing medications.
  • The patient is no longer showing symptoms, including cough.
  • The patient has tested negative on at least two consecutive respiratory specimens collected at least 24 hours apart.

Someone who has been released from isolation is not considered to pose a risk of infection to others.

 

Can someone who has been quarantined for COVID-19 spread the illness to others?

Quarantine means separating a person or group of people who have been exposed to a contagious disease but have not developed illness (symptoms) from others who have not been exposed, in order to prevent the possible spread of that disease. Quarantine is usually established for the incubation period of the communicable disease, which is the span of time during which people have developed illness after exposure. For COVID-19, the period of quarantine is 14 days from the last date of exposure, because 14 days is the longest incubation period seen for similar coronaviruses. Someone who has been released from COVID-19 quarantine is not considered a risk for spreading the virus to others because they have not developed illness during the incubation period.

 

Can the virus that causes COVID-19 be spread through food including refrigerated or frozen food?

Coronaviruses are generally thought to be spread from person-to-person through respiratory droplets. Currently there is no evidence to support transmission of COVID-19 associated with food. Before preparing or eating food it is important to always wash your hands with soap and water for 20 seconds for general food safety. Throughout the day wash your hands after blowing your nose, coughing or sneezing, or going to the bathroom.

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, but this is not thought to be the main way the virus spreads.

In general, because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from food products or packaging that are shipped over a period of days or weeks at ambient, refrigerated, or frozen temperatures.

 

Will warm weather stop the outbreak of COVID-19?

It is not yet known whether weather and temperature impact the spread of COVID-19. Some other viruses, like the common cold and flu, spread more during cold weather months but that does not mean it is impossible to become sick with these viruses during other months.  At this time, it is not known whether the spread of COVID-19 will decrease when weather becomes warmer.  There is much more to learn about the transmissibility, severity, and other features associated with COVID-19 and investigations are ongoing.

 

What is community spread?

Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.

 

COVID-19 FAQS

How to protect yourself

Am i at risk for COVID-19 in the United States?

This is a rapidly evolving situation and the risk assessment may change daily. The latest updates are available on CDC’s Coronavirus Disease 2019 (COVID-19) website.

 

Has anyone in the United States gotten infected?

Yes. There have been cases of COVID-19 in the U.S. related to travel and through close contact. U.S. case counts are updated regularly Mondays through Fridays. 

 

How can i help protect myself?

Visit the COVID-19 Prevention and Treatment page to learn about how to protect yourself from respiratory illnesses, like COVID-19.

what should i do if i had close contact with someone who has COVID-19?

There is information for people who have had close contact with a person confirmed to have, or being evaluated for, COVID-19 available online.

 

Who is at higher risk for serious illness from COVID-19?

Older adults and people of any age who have serious underlying medical conditions may be at higher risk for more serious complications from COVID-19.  Based upon available information to date, those most at risk include

  • People 65 years and older
  • People who live in a nursing home or long-term care facility
  • People of any age with the following underlying medical conditions, particularly those that are not well controlled
    • Chronic lung disease or asthma
    • Congestive heart failure or coronary artery disease
    • Diabetes
    • Neurologic conditions that weaken ability to cough
    • Weakened immune system
    • Chemotherapy or radiation for cancer (currently or in recent past)
    • Sickle cell anemia
    • Chronic kidney disease requiring dialysis
    • Cirrhosis of the liver
    • Lack of spleen or a spleen that doesn’t function correctly
    • Extreme obesity (body mass index [BMI] >40)
  • People who are pregnant

 

What should people at higher risk of serious illness with COVID-19 do?

If you are at higher risk of getting very sick from COVID-19, you should: stock up on supplies; take everyday precautions to keep space between yourself and others; when you go out in public, keep away from others who are sick; limit close contact and wash your hands often; and avoid crowds, cruise travel, and non-essential travel. If there is an outbreak in your community, stay home as much as possible. Watch for symptoms and emergency signs. If you get sick, stay home and call your doctor. More information on how to prepare, what to do if you get sick, and how communities and caregivers can support those at higher risk is available on People at Risk for Serious Illness from COVID-19

 

Does CDC recommend the use of facemask to prevent COVID-19?

CDC does not recommend that people who are well wear a facemask to protect themselves from respiratory illnesses, including COVID-19. You should only wear a mask if a healthcare professional recommends it. A facemask should be used by people who have COVID-19 and are showing symptoms. This is to protect others from the risk of getting infected. The use of facemasks also is crucial for health workers and other people who are taking care of someone infected with COVID-19 in close settings (at home or in a health care facility).

 

Am i at risk for COVID-19 from a package or products shipping from China?

There is still a lot that is unknown about the newly emerged COVID-19 and how it spreads. Two other coronaviruses have emerged previously to cause severe illness in people (MERS-CoV and SARS-CoV). The virus that causes COVID-19 is more genetically related to SARS-CoV than MERS-CoV, but both are betacoronaviruses with their origins in bats. While we don’t know for sure that this virus will behave the same way as SARS-CoV and MERS-CoV, we can use the information gained from both of these earlier coronaviruses to guide us. In general, because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures. Coronaviruses are generally thought to be spread most often by respiratory droplets. Currently there is no evidence to support transmission of COVID-19 associated with imported goods and there have not been any cases of COVID-19 in the United States associated with imported goods. Information will be provided on the Coronavirus Disease 2019 (COVID-19) website as it becomes available.

 

Is it okay for me to donate blood?

In healthcare settings all across the United States, donated blood is a lifesaving, essential part of caring for patients. The need for donated blood is constant, and blood centers are open and in urgent need of donations. CDC encourages people who are well to continue to donate blood if they are able, even if they are practicing social distancing because of COVID-19. CDC is supporting blood centers by providing recommendations that will keep donors and staff safe. Examples of these recommendations include spacing donor chairs 6 feet apart, thoroughly adhering to environmental cleaning practices, and encouraging donors to make donation appointments ahead of time.

COVID-19 and children

What is the risk of my child becoming sick with COVID-19?

Based on available evidence, children do not appear to be at higher risk for COVID-19 than adults. While some children and infants have been sick with COVID-19, adults make up most of the known cases to date. You can learn more about who is most at risk for health problems if they have COVID-19 infection on CDC’s current Risk Assessment page.

 

How can i protect my child from COVID-19 infection?

You can encourage your child to help stop the spread of COVID-19 by teaching them to do the same things everyone should do to stay healthy.

  • Clean hands often using soap and water or alcohol-based hand sanitizer
  • Avoid people who are sick (coughing and sneezing)
  • Clean and disinfect high-touch surfaces daily in household common areas (e.g. tables, hard-backed chairs, doorknobs, light switches, remotes, handles, desks, toilets, sinks)
  • Launder items including washable plush toys as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry from an ill person can be washed with other people’s items.

 

Are the symptoms of COVID-19 different in children than in adults?

No. The symptoms of COVID-19 are similar in children and adults. However, children with confirmed COVID-19 have generally presented with mild symptoms. Reported symptoms in children include cold-like symptoms, such as fever, runny nose, and cough. Vomiting and diarrhea have also been reported. It’s not known yet whether some children may be at higher risk for severe illness, for example, children with underlying medical conditions and special healthcare needs. There is much more to be learned about how the disease impacts children.

 

Should children wear masks?

No. If your child is healthy, there is no need for them to wear a facemask. Only people who have symptoms of illness or who are providing care to those who are ill should wear masks.

 

COVID-19 FAQS

Preparing Your home for COVID-19

How can my family and I prepare for COVID-19?

Create a household plan of action to help protect your health and the health of those you care about in the event of an outbreak of COVID-19 in your community:

  • Talk with the people who need to be included in your plan, and discuss what to do if a COVID-19 outbreak occurs in your community.
  • Plan ways to care for those who might be at greater risk for serious complications, particularly older adults and those with severe chronic medical conditions like heart, lung or kidney disease.
    • Make sure they have access to several weeks of medications and supplies in case you need to stay home for prolonged periods of time.
  • Get to know your neighbors and find out if your neighborhood has a website or social media page to stay connected.
  • Create a list of local organizations that you and your household can contact in the event you need access to information, healthcare services, support, and resources.
  • Create an emergency contact list of family, friends, neighbors, carpool drivers, health care providers, teachers, employers, the local public health department, and other community resources.

 

What steps can my family take to reduce our risk of getting COVID-19?

Practice everyday preventive actions to help reduce your risk of getting sick and remind everyone in your home to do the same. These actions are especially important for older adults and people who have severe chronic medical conditions:

  • Avoid close contact with people who are sick.
  • Stay home when you are sick, except to get medical care.
  • Cover your coughs and sneezes with a tissue and throw the tissue in the trash.
  • Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Clean and disinfect frequently touched surfaces and objects
    (e.g., tables, countertops, light switches, doorknobs, and cabinet handles).

 

What should I do if someone in my house gets sick with COVID-19?

Most people who get COVID-19 will be able to recover at home. CDC has directions for people who are recovering at home and their caregivers, including:

  • Stay home when you are sick, except to get medical care.
  • If you develop emergency warning signs for COVID-19 get medical attention immediately. In adults, emergency warning signs*:
    • Difficulty breathing or shortness of breath
    • Persistent pain or pressure in the chest
    • New confusion or inability to arouse
    • Bluish lips or face
    • *This list is not all inclusive. Please consult your medical provider for any other symptom that is severe or concerning.
  • Use a separate room and bathroom for sick household members (if possible).
  • Clean hands regularly by handwashing with soap and water or using an alcohol-based hand sanitizer with at least 60% alcohol.
  • Provide your sick household member with clean disposable facemasks to wear at home, if available, to help prevent spreading COVID-19 to others.
  • Clean the sick room and bathroom, as needed, to avoid unnecessary contact with the sick person.
  • Avoid sharing personal items like utensils, food, and drinks.

 

How can i prepare in case my child's school, childcare facility, or university is dismissed?

Talk to the school or facility about their emergency operations plan. Understand the plan for continuing education and social services (such as student meal programs) during school dismissals. If your child attends a college or university, encourage them to learn about the school’s plan for a COVID-19 outbreak.

 

Should i use soap and water or a hand sanitizer to protect against COVID-19?

Handwashing is one of the best ways to protect yourself and your family from getting sick. Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol.

 

What cleaning products should i use to protect against COVID-19?

Clean and disinfect frequently touched surfaces such as tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.  If surfaces are dirty, clean them using detergent or soap and water prior to disinfection. To disinfect, most common EPA-registered household disinfectants will work. See CDC’s recommendations for household cleaning and disinfection.
