FAQ

About COVID-19

○ Coronaviruses are zoonotic, meaning that they are transferred to animals and humans. There were originally six types of coronaviruses known to be transmittable to humans.

○ Among these six types, four types cause illnesses like the flu, and the other two are called MERS-CoV and SARS-CoV.

○ Sequencing has confirmed that the causative virus of this outbreak – the novel coronavirus (SARS-CoV-2) – is an 89.1% match with SARS-like virus originating from bats.
○ COVID-19 is transmitted through respiratory droplets produced when an infected person coughs or sneezes. The virus is transmitted by these droplets that are inhaled by other people or from people touching their eyes, nose, and mouth with hands with the virus on them.

○ In addition, since touching surfaces with droplets produced by infected people on them and then touching the eyes, nose, and mouth can transmit the virus, it is imperative that you wash your hands thoroughly.
○ The most common symptoms of COVID-19 are fever, fatigue, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell.

○ Most people (about 80%) recover from the disease without needing special treatment, but older people, and those with underlying medical problems such as high blood pressure, heart problems or diabetes, are more likely to develop serious illness, which is why people with fever, cough and difficulty breathing should seek medical attention.

○ The main way the disease spreads is through inhaling respiratory droplets expelled by someone who is coughing or contact. The risk of catching COVID-19 from someone with no symptoms at all is very low. However, many people with COVID-19 experience only mild symptoms, which is why it is possible to catch COVID-19 from someone who has little to no symptoms.

○ WHO is assessing ongoing research on the period of transmission of COVID-19 and will share updated findings.

Persons in Contact with Suspected Cases

○ The criteria is determined based on an exposure assessment conducted by emergency response teams in each city and province.

○ The scope of exposure starts two days before the confirmed patient started showing symptoms (for asymptomatic patients, two days before samples were collected), taking into account the symptoms displayed by the confirmed patient, whether the confirmed patient was wearing a mask, and risk level of exposure (location of contact, duration of contact, etc.).
○ Health care workers who use and dispose of personal protective equipment* in a manner deemed proper by each medical center are not classified as contacts.

○ A final decision is made on the scope of contact taking into account the symptoms displayed by the confirmed patient, whether the confirmed patient was wearing a mask, risk level of exposure, duration, etc.

* Refer to Response Guidelines for Coronavirus-19 (local governments) Edition 7-4, Appendix p19
○ Contacts should isolate themselves (self-quarantine, at separate facilities or hospitals) for 14 days from the point of last potential exposure from a confirmed case.

○ The director or governor of the city or province, or the mayor or governor of the county the county in question issues a quarantine notice, provides information about isolation rules, and designates an official who will be in charge of reaching out to the quarantined individual twice a day via phone call until the quarantine is lifted to check for fevers or respiratory symptoms.
○ Separate yourself from other people and frequently ventilate the room by closing the door and opening the windows. If possible, stay in a place where you can have a separate bathroom and basin to yourself.

○ If you use a public bathroom or basin, make sure you have disinfected the area with bleach or other household disinfectants before other people use them.

○ Use your own personal items, including towels, dishware, and mobile phone. Wash your clothes and bedding separately. Eat alone and make sure to separate your dishware from everyone else’s and clean them thoroughly before anyone else uses them.
○ If you are unable to find a separate living area within your residence or require additional assistance, you may stay at a suitable self-quarantine facility or an isolation room at a hospital within your local community.
○ Yes, your expenses will be covered during the self-quarantine period and you will be on paid leave. For details, contact your Community Service Center.

* Although living expenses are not covered for overseas travelers during their isolation period, assistance such as daily necessities is provided in order to ensure minimum living standards
○ According to Article 79-3 of the Infectious Disease Control and Prevention Act, violations are punishable by a maximum one year prison sentence or maximum KRW 10 million fine (enacted April 5, 2020).
○ No, you may not leave the country. Once you receive a Self-quarantine Notice from the Health Service, you are prohibited from engaging in public activities or leaving the country during the isolation period, regardless of whether or not you are showing symptoms.
○ Since South Korea raised the alert level for COVID-19 to “serious” on February 23, 2020, location tracing information of confirmed patients are published on each local governments’ official website.

Testing

○ In accordance with the case definitions provided for in these guidelines, patients classified as suspected cases and Patients Under Investigation (PUI) may get tested.

○ There is no need to get tested out of simple anxiety. We ask that you trust the expert advice of your physicians.

Suspected Cases

A person who develops a fever or respiratory symptoms (coughing, difficulty breathing, etc.) within 14 days of coming into contact with a confirmed patient

Patients Under Investigation

① A person who is suspected of having the COVID-19 virus as per doctor’s diagnosis of pneumonia of unknown causes.

② A person who develops a fever (37.5℃ and above) or respiratory symptoms (coughing, difficulty breathing, etc.) within 14 days of travelling overseas
③ A person with an epidemiologic link to a collective outbreak of COVID-19 in Korea and develops a fever (37.5℃ and above) or respiratory symptoms (coughing, difficulty breathing, etc.) within 14 days.

○ You can get tested at COVID-19 screening centers or medical centers that are equipped to collect samples.

○ A list of screening centers where you can get tested for COVID-19 are provided on the KCDC website.

※ KCDC website → COVID-19 → Find a Screening Center or Public Relief Hospital

○ For further inquiries, please contact the KCDC call center (☎1339 or region code + 120) or public health clinic.
○ (Sample collection) Samples are collected by physicians, nurses, and medical technicians at designated locations (COVID-19 screening centers, etc.). Upper respiratory tract sampling is mandatory, while lower respiratory tract sampling is optional for patients with sputum. You may experience discomfort/pain while the sample is being collected.

※ Nurses and medical technicians will collect samples under the guidance of physicians.

Upper respiratory

tract sample

Combination of a nasal (nasopharyngeal) and throat (oropharyngeal) swab (in one tube)

- (Nasal swab) insert a cotton swab into the nostril until it reaches the posterior nares

- (Throat swab) insert a cotton swab and scrape the insides of the throat

Lower respiratory tract sample

Sample is collected by spitting sputum into a container, making sure that it is not contaminated by other liquids

- Forcefully coughing up sputum is strictly prohibited as it may produce aerosol



○ (DNA testing) screening centers that are not equipped to do their own testing will send tests to reference laboratories.
○ DNA testing itself takes about six hours. However, the sample will need to be transferred and there may be delays. You can expect to get your results back in one to two days after testing.
○ You will not be charged for testing if you are registered as a suspected case or Patient Under Investigation. However, you will still be charged for general check-ups, X-rays, and other tests and treatment.

○ The same shall apply to both Koreans and foreigners.
○ Yes. A sample of the upper respiratory tract is required and a sample of both the upper and lower respiratory tract will be taken for patients with sputum. However, sputum should not be forcefully coughed up under any circumstances.
○ No. A negative pressure chamber is not necessary, but make sure you collect the sample in an isolated area that not have internal circulation and is well-ventilated as there is risk of producing aerosol.
○ Standard precautions are the most basic precautionary guidelines for all treatment, procedures, and nursing of patients within medical centers and is applied universally in order to prevent infectious diseases from spreading.

○ A patient’s blood, bodily fluids, secretion, excrement, damaged skin and mucous should be treated in accordance with standard precautions. There are precautionary measures for contact depending on the transmission pathway, droplets (for diseases that are transmitted by droplets larger than five micrometers), and air.

Treatment

○ Not yet. To date, there is no vaccine for COVID-19.
○ The treatment for COVID-19 is symptomatic treatment (treating the symptoms of a disease).

○ The absence of a treatment for COVID-19 means that we do not yet have a targeted therapy designed for the COVID-19 virus or to treat sick cells. It does not mean that the virus is not treatable.
○ In accordance with the Infectious Disease Control and Prevention Act, treatment is covered by the local or central government.

○ The same shall apply to both Koreans and foreigners.

Imposition of and Release from Quarantine

○ Cohort isolation is used to separate a group of patients (cohort) exposed to or infected by the same pathogen in the same hospital room or ward. The cohorts are groups based on the results of microbiological testing and clinical diagnosis depending on the epidemiology of the source of infection or method of transmission.
○ Cohort isolation is used when numerous patients require treatment where precautionary measures need to be taken to prevent transmission and the number of separate hospital rooms are in short supply.

○ It’s critical that hospital beds be placed at least 2 meters apart and curtains may be used as additional physical barriers.
○ If a patient’s PCR test taken on the seventh day after confirmation is positive, another test is taken after seven days (14th day after confirmation). If this test once again returns positive, the quarantine will be lifted if two tests taken at a 24 hour interval at a date determined at the discretion of the physicians both produce negative results.
○ The quarantine will be lifted for a confirmed patient in cohort isolation if he/she does not develop a fever without medication, other clinical symptoms improve, and tests negative for two tests performed at a 24 hour interval.

○ However, even if other patients do not meet the criteria for their quarantine to be lifted, an individual in cohort isolation may be released from quarantine if he/she meets both clinical and testing criteria.
○ Symptomatic confirmed patients must meet both clinical and testing criteria to be released from quarantine. The clinical criteria is that the patient does not develop a fever without the help of medication and clinical symptoms must improve. The testing criteria requires that patients PCR test performed twice at a 24 hour interval both come back negative in order to be released from quarantine.

○ Patients who fail to meet the testing criteria, but meet the clinical criteria may be released from the hospital and put under self-quarantine or quarantine at a separate facility. However, the testing criteria must be met for the quarantine to be lifted.

Travel

○ Extra precautions must be taken for overseas travel given the global spread of COVID-19. Refer to global updates about the virus at “Overseas Infectious Diseases NOW” published by KCDC and make sure to check the “Safe Overseas Travel” website published by the Ministry of Foreign Affairs for a list of countries that have banned entry of Korean travelers and countries that have imposed restrictions on entry as a part of quarantine and other disease prevention measures.

Quarantine Insepction

○ All passengers arriving in Korea – both Korean nationals and foreign nationals – must fill out a Health Declaration Form and report their travel record and health conditions. In addition, inbound travelers must submit a special immigration form in accordance with special immigration procedures. Passengers will be allowed entry only if they are able to provide verifiable contact information and address for their stay in Korea. Furthermore, all inbound travelers must install the Mobile Self-diagnosis App on their phone that will be used to check their risk level of infection. Travelers must enter their symptoms once a day on the app for a 14 day period beginning on the day after arrival.
○ Passengers with fevers or displaying respiratory symptoms that are deemed to have an epidemiological link to the virus during quarantine inspection will be diagnosed and tested at an isolation facility within the quarantine station and will be placed under temporary quarantined observation until the test results come back.

○ Korean nationals who do not show symptoms during quarantine inspection must get samples collected, diagnosed, and tested at a public health clinic within their jurisdiction within three days of arrival and be placed under self-quarantine for 14 days after arrival.

○ Foreign nationals who do not show symptoms will have their samples collected, diagnosed, and tested and will be required to wait at a separate facility until the test results come back. If the test results are negative, as is the case with Korean nationals, long-term stay foreigners will be placed under self-quarantine. However, short-term stay foreigners will be quarantined in a designated facility for the 14 day incubation period.

○ Meanwhile, inbound travelers who test positive will be transferred to an isolated treatment ward or Living Treatment Center to get treatment.
○ Passengers with fevers or displaying respiratory symptoms that are deemed to have an epidemiological link to the virus during quarantine inspection will be diagnosed and tested at an isolation facility within the quarantine station and will be placed under temporary quarantined observation until the test results come back.

○ Asymptomatic Korean nationals and long-term stay foreigners who do not display symptoms during quarantine inspection will be placed under self-quarantine for 14 days upon arrival and will be required to get diagnosed and tested if they start to develop fevers or respiratory symptoms.

○ Asymptomatic short-term stay foreigners who do not display symptoms during quarantine inspection will be placed under quarantine at a separate facility for 14 days upon arrival and will have their samples collected, diagnosed, and tested if they develop COVID-19 symptoms during their stay at the quarantine facility.

* Even if diagnosis and testing results return negative, individuals remain quarantined in separate facilities for the 14 day incubation period.

○ Meanwhile, inbound travelers who test positive will be transferred to an isolated treatment ward or Living Treatment Center to get treatment.

Others

○ Multi-purpose facilities are recommended to follow basic measures such as providing hand sanitizers out on display and requiring employees to wear masks prevent infections. Refer to the strict infection prevention guidelines that are in place for multi-purposed events.
※ Refer to Guidelines on Disinfecting Public Facilities and Multi-purpose Facilities (edition 3-1)

○ Identify where the patient has been and decide on the scope and method of disinfection.

○ If unable to identify where the patient has been, map out a disinfection plan based on areas most used and in contact with the general public.

○ Areas (zones) within the multi-purpose facility that the patient has not used may be disinfected by the facility operators as normal.

○ Areas that the patient used and require disinfection must be cleared out. The time it takes to reopen the disinfected space for use will differ depending on the type of disinfectant and ventilation methods used.

- Although the virus will die after disinfection, reopening the space to the general public must take into careful consideration the nature of the disinfectant that was used.

○ Given the odor and toxicity of sodium hypochlorite (household bleach), areas disinfected with sodium hypochlorite should be ventilated until the day after disinfection and may be used the next day.
○ There is still a lot we do not know about the transmission pathway of COVID-19.

○ The survival span of the virus varies depending on surface materials, surrounding temperature, humidity, and other environmental factors. It has been reported that the virus may survive for days, but the risk of contracting the virus from products or packages that are shipped for days or weeks at room temperature is extremely low.

○ According to the United States CDC, “as of now, there is no evidence to support the theory that COVID-19 is transmitted by imported products and there have not been any COVID-19 cases reported concerning imported products.”

○ Updated findings that are published will be shared later on.
