ERS COVID-19 resource centre

The ERS COVID-19 resource centre brings together all European Respiratory Society (ERS) and European Lung Foundation (ELF) resources on SARS-CoV-2 and COVID-19 as it is published.

ERS is committed to supporting health workers during these challenging times by providing up-to-date information and a variety of educational resources, all of which are free-to-access.


ERS's Daily round-up features the latest news, research and clinical trials related to SARS-CoV-2 and COVID-19 as selected by a reviewer.


A dedicated space for ERS members and the wider healthcare community to connect, discuss and share your experiences of COVID-19. Sign in with your myERS details and join a discussion.


Healthcare workers on the front lines share their stories of treating and managing COVID-19.

ERS Publications

The latest articles from ERS publications on SARS-CoV-2 and COVID-19. All articles are available via open access.


An international directory of guidelines and best practice recommendations prepared by ERS partner societies around the world focused on the management and care of COVID-19.

Webinars and video series

Expert-led webinars that provide updates on the management of COVID-19 in China, clinical consequences, epidemiology and research potential.


Recent presentations and training materials focused on ventilation and the mechanics of breathing.


Access and contribute to ongoing COVID-19 surveys that are led or endorsed by ERS. Your responses help to advance understanding of COVID-19 across respiratory specialities.

Research summaries

ERS Respiratory Digests provide summaries of new and significant research, including important early COVID-19 publications.


Access ELF materials for respiratory patients, relatives and caregivers, developed with ERS experts and available in multiple languages.

Outbreak summary and updates

What is the novel coronavirus?

Coronaviruses are a large family of viruses that can cause illness ranging from the common cold to more severe diseases like Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

The 2019 novel coronavirus, called 'SARS-CoV-2' (previously referred to as 2019-nCoV), is a new strain that has not been identified in humans before. The disease that is caused by SARS-CoV-2 is called 'COVID-19'.

Outbreak summary

On 31 December 2019, the World Health Organization (WHO) was informed of several cases of viral pneumonia of unknown cause detected in Wuhan City, China.

The outbreak has rapidly evolved, affecting other parts of China and many countries worldwide in Asia, Europe, North and South America, Australia and Africa. On 11 March 2020, WHO labelled the COVID-19 outbreak as a pandemic.

ERS recommends consulting the WHO's daily situation reports for the latest updates on the number of people who are being treated for COVID-19 and the geographic spread of SARS-CoV-2.

What are the symptoms of COVID-19?

Typical symptoms of COVID-19 include fever, cough, difficulty breathing, muscle pain and tiredness. More serious cases can develop severe pneumonia, acute respiratory distress syndrome, sepsis and septic shock. Anosmia – loss of the sense of smell or sometimes the sense of taste – has also been reported as a symptom of COVID-19 infection.

Generally, older people and those with underlying conditions (such as hypertension, heart disorders, diabetes, liver disorders, and respiratory disease) are expected to be more at risk of developing severe symptoms.

The evidence from analyses of cases to date is that COVID-19 infection causes mild disease (i.e. non-pneumonia or mild pneumonia) in about 80% of cases and most cases recover; 14% have more severe disease and 6% experience critical illness.

How does COVID-19 spread?

COVID-19 is transmitted from human-to-human mainly via flu-like symptoms and respiratory droplets that people sneeze, cough, or exhale. These droplets land on objects and surfaces, and others can catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 by breathing in droplets from a person with COVID-19 who coughs or exhales droplets.

The infectious period may begin 1–2 days before symptoms appear, but people are likely most infectious during the symptomatic period, even if symptoms are mild. The infectious period is estimated to last for 7–12 days in moderate cases and up to 2 weeks in severe cases.

How is COVID-19 treated?

In severe cases of COVID-19, patients who are hospitalised may be intubated using a ventilator in order to support their ability to breathe. The European Lung Foundation (ELF) has prepared a factsheet that explains what will happen once a person goes into hospital, how their symptoms will be managed and what will happen if they get put on a ventilator. Access the ELF factsheet - available in multiple languages.

On 25 June 2020, the European Medicine Agency’s human medicines committee (CHMP) recommended granting a conditional marketing authorisation to remdesivir for the treatment of COVID-19 in adults and adolescents from 12 years of age with pneumonia who require supplemental oxygen. Remdesivir is the first medicine against COVID-19 to be recommended for authorisation in the EU.

However, it is important to emphasise that research is continuing for the development of a vaccine that protects against SARS-CoV-2, as well as drugs that can effectively treat COVID-19. ERS is monitoring the development of vaccines and recommends health professionals and the public to follow the advice of the EMA regarding vaccination.

What is the situation in the European region?

There is an ongoing COVID-19 outbreak in the EU/EEA and UK. Up-to-date confirmed case and death counts for the region can be accessed in European Centre for Disease Prevention and Control's (ECDC) daily update.

In its latest risk report, the ECDC has analysed the risk posed to the general population, vulnerable individuals, and healthcare provision by the current increase in COVID-19 case notification rates observed in the EU/EEA and the UK. The ECDC's risk assessment reports:

  • In countries observing stable and low notification rates, and low test positivity, the risk of COVID-19 for the general population and for healthcare provision is low, based on a low probability of infection and low impact of the disease. Regarding vulnerable individuals, the overall risk is moderate based on a low probability of infection and very high impact of the disease.

  • In countries observing high or sustained increase in notification rates, or high test positivity, but with high testing rates and transmission occurring primarily in young individuals**, the risk of COVID-19 is moderate for the general population and for healthcare provision, based on a very high probability of infection and low impact of the disease. However, the risk of COVID-19 is very high for vulnerable individuals, based on a very high probability of infection and very high impact of the disease.

  • In countries observing high or sustained increase in notification rates, or high test positivity, and an increasing proportion of older cases, and/or high or increasing COVID-19 mortality, the risk of COVID-19 is high for the general population, based on a very high probability of infection and moderate impact of the disease.However, the risk of COVID-19 is very high for vulnerable individuals, based on a very high probability of infection and very high impact of the disease.

Advice for healthcare professionals and scientists

As with SARS and MERS, when dealing with patients who may have COVID-19, health professionals should follow airborne precautions and wear respiratory masks (N95 or higher) during intubation and when entering a negative pressure room. Healthcare professionals are advised to consult the:
