Frequently Asked Questions

COVID-19 is the disease caused by a new coronavirus called SARS-CoV-2.  WHO first learned of this new virus on 31 December 2019, following a report of a cluster of cases of ‘viral pneumonia’ in Wuhan, People’s Republic of China.

The most common symptoms of COVID-19 are

  • Fever
  • Dry cough
  • Fatigue

Other symptoms that are less common and may affect some patients include:

  • Loss of taste or smell,
  • Nasal congestion,
  • Conjunctivitis (also known as red eyes)
  • Sore throat,
  • Headache,
  • Muscle or joint pain,
  • Different types of skin rash,
  • Nausea or vomiting,
  • Diarrhea,
  • Chills or dizziness.

 

Symptoms of severe COVID‐19 disease include:

  • Shortness of breath,
  • Loss of appetite,
  • Confusion,
  • Persistent pain or pressure in the chest,
  • High temperature (above 38 °C).

Other less common symptoms are:

  • Irritability,
  • Confusion,
  • Reduced consciousness (sometimes associated with seizures),
  • Anxiety,
  • Depression,
  • Sleep disorders,
  • More severe and rare neurological complications such as strokes, brain inflammation, delirium and nerve damage.

People of all ages who experience fever and/or cough associated with difficulty breathing or shortness of breath, chest pain or pressure, or loss of speech or movement should seek medical care immediately. If possible, call your health care provider, hotline or health facility first, so you can be directed to the right clinic.

Among those who develop symptoms, most (about 80%) recover from the disease without needing hospital treatment. About 15% become seriously ill and require oxygen and 5% become critically ill and need intensive care.

Complications leading to death may include respiratory failure, acute respiratory distress syndrome (ARDS), sepsis and septic shock, thromboembolism, and/or multiorgan failure, including injury of the heart, liver or kidneys.

In rare situations, children can develop a severe inflammatory syndrome a few weeks after infection. 

People aged 60 years and over, and those with underlying medical problems like high blood pressure, heart and lung problems, diabetes, obesity or cancer, are at higher risk of developing serious illness. 

However, anyone can get sick with COVID-19 and become seriously ill or die at any age. 

Some people who have had COVID-19, whether they have needed hospitalization or not, continue to experience symptoms, including fatigue, respiratory and neurological symptoms.

WHO is working with our Global Technical Network for Clinical Management of COVID-19, researchers and patient groups around the world to design and carry out studies of patients beyond the initial acute course of illness to understand the proportion of patients who have long term effects, how long they persist, and why they occur.  These studies will be used to develop further guidance for patient care.

Stay safe by taking some simple precautions, such as physical distancing, wearing a mask, especially when distancing cannot be maintained, keeping rooms well ventilated, avoiding crowds and close contact, regularly cleaning your hands, and coughing into a bent elbow or tissue.

Anyone with symptoms should be tested, wherever possible. People who do not have symptoms but have had close contact with someone who is, or may be, infected may also consider testing – contact your local health guidelines and follow their guidance.  

While a person is waiting for test results, they should remain isolated from others. Where testing capacity is limited, tests should first be done for those at higher risk of infection, such as health workers, and those at higher risk of severe illness such as older people, especially those living in seniors’ residences or long-term care facilities.

Rapid antigen tests (sometimes known as a rapid diagnostic test – RDT) detect viral proteins (known as antigens). Samples are collected from the nose and/or throat with a swab. These tests are cheaper than PCR and will offer results more quickly, although they are generally less accurate. These tests perform best when there is more virus circulating in the community and when sampled from an individual during the time they are most infectious.

Antibody tests can tell us whether someone has had an infection in the past, even if they have not had symptoms. Also known as serological tests and usually done on a blood sample, these tests detect antibodies produced in response to an infection. In most people, antibodies start to develop after days to weeks and can indicate if a person has had past infection. Antibody tests cannot be used to diagnose COVID-19 in the early stages of infection or disease but can indicate whether or not someone has had the disease in the past.

 

 

The time from exposure to COVID-19 to the moment when symptoms begin is, on average, 5-6 days and can range from 1-14 days. This is why people who have been exposed to the virus are advised to remain at home and stay away from others, for 14 days, in order to prevent the spread of the virus, especially where testing is not easily available.

Yes. There are three COVID-19 vaccines for which certain national regulatory authorities have authorized the use. None have yet received WHO EUL/PQ authorization but we expect an assessment on the Pfizer vaccine by the end of December and for some other candidates soon thereafter. 

Large studies of 5 vaccine candidates efficacy and safety results, including these three (and for Moderna and AstraZeneca), have been publicly reported  through press releases but only one (AstraZeneca) has published results in the peer reviewed literature.  , We expect more such reports in the near future.  It is likely that additional candidates will be submitted to regulatory authorities for approval. There are many potential COVID-19 vaccine candidates currently in development.

Once vaccines are demonstrated to be safe and efficacious, they must be approved by national regulators, manufactured to exacting standards, and distributed. WHO is working with partners around the world to help coordinate key steps in this process, including to facilitate equitable access to safe and effective COVID-19 vaccines for the billions of people who will need them. More information about COVID-19 vaccine development is available here.

 

 

 

If you have any symptoms suggestive of COVID-19, call your health care provider or COVID-19 hotline for instructions and find out when and where to get a test, stay at home for 14 days away from others and monitor your health.

If you have shortness of breath or pain or pressure in the chest, seek medical attention at a health facility immediately. Call your health care provider or hotline in advance for direction to the right health facility.

If you live in an area with malaria or dengue fever, seek medical care if you have a fever.

If local guidance recommends visiting a medical centre for testing, assessment or isolation, wear a medical mask while travelling to and from the facility and during medical care. Also keep at least a 1-metre distance from other people and avoid touching surfaces with your hands.  This applies to adults and children.

Scientists around the world are working to find and develop treatments for COVID-19.

Optimal supportive care includes oxygen for severely ill patients and those who are at risk for severe disease and more advanced respiratory support such as ventilation for patients who are critically ill.

Dexamethasone is a corticosteroid that can help reduce the length of time on a ventilator and save lives of patients with severe and critical illness. Read our dexamethasone Q&A for more information.  

Results from the WHO’s Solidarity Trial indicated that remdesivir, hydroxychloroquine, lopinavir/ritonavir and interferon regimens appear to have little or no effect on 28-day mortality or the in-hospital course of COVID-19 among hospitalized patients.

Hydroxychloroquine has not been shown to offer any benefit for treatment of COVID-19. Read our hydroxychloroquine Q&A for more information.

WHO does not recommend self-medication with any medicines, including antibiotics, as a prevention or cure for COVID-19. WHO is coordinating efforts to develop treatments for COVID-19 and will continue to provide new information as it becomes available.

Antibiotics do not work against viruses; they only work on bacterial infections. COVID-19 is caused by a virus, so antibiotics do not work. Antibiotics should not be used as a means of prevention or treatment of COVID-19.

In hospitals, physicians will sometimes use antibiotics to prevent or treat secondary bacterial infections which can be a complication of COVID-19 in severely ill patients. They should only be used as directed by a physician to treat a bacterial infection.
