WHO RISK ASSESSMENT

SUBJECT IN FOCUS: CLINICAL MANAGEMENT OF PATIENTS WITH COVID-19

WHO is working closely with clinicians caring for patients with COVID-19, in China and across the globe and international experts on infectious disease to better understand, in real time, the clinical presentation, natural history and treatment interventions for COVID-19.

A majority of patients with COVID-19 are adults. Among 44 672 patients in China with confirmed infection, 2.1% were below the age of 20¹. The most commonly reported symptoms included fever, dry cough, and shortness of breath, and most patients (80%) experienced mild illness. Approximately 14% experienced severe disease and 5% were critically ill. Early reports suggest that illness severity is associated with age (>60 years old) and co-morbid disease.

Clinical care of patients with COVID-19 focuses on early recognition, immediate isolation and implementation of appropriate infection prevention and control (IPC) measures; provision of symptomatic care for those with mild illness; and optimized supportive care for those with severe disease. WHO has published patient management guidance, including interim clinical care guidance for hospitalized patients and home care guidance for those with mild disease that may be treated at home in isolation when the health system is strained.

Oxygen therapy is the major treatment intervention for patients with severe COVID-19. All countries should work to optimize the availability of pulse oximeters and medical oxygen systems. Mortality in those with critical illness has been reported as over 50%, thus implementation of proven critical care interventions such as lung protective ventilation should be optimized. COVID-19 critical care clinical training materials are available on https://openwho.org/courses/severe-acute-respiratory-infection. The first regional COVID-19 Clinical Case Management training was conducted in Brazzaville from 25-28 February 2020 with representatives from 18 countries of the WHO African region. WHO will continue to conduct such trainings to increase global knowledge on the management and care of patients with COVID-19.

WHO launched the Global COVID-19 Clinical Data Platform to aggregate and report on clinical severity to inform the public health response. Member States are encouraged to contribute by contacting Cette adresse email est protégée contre les robots des spammeurs, vous devez activer Javascript pour la voir. for log-in information.

As there is currently no known effective antiviral therapy for COVID-19, the WHO R&D Blueprint has prioritized investigational therapeutics and developed a master randomized clinical trial protocol that can be used and adapted at the national level. There are many ongoing ethics-approved clinical trials evaluating a number of different therapeutic interventions globally including priority agents such as ritonavir/lopinavir and remdesivir.

STRATEGIC OBJECTIVES

WHO’s strategic objectives for this response are to:

• Interrupt human-to-human transmission including reducing secondary infections among close contacts and health care workers, preventing transmission amplification events, and preventing further international spread*;
• Identify, isolate and care for patients early, including providing optimized care for infected patients;
• Identify and reduce transmission from the animal source;
• Address crucial unknowns regarding clinical severity, extent of transmission and infection, treatment options, and accelerate the development of diagnostics, therapeutics and vaccines;
• Communicate critical risk and event information to all communities and counter misinformation;
• Minimize social and economic impact through multisectoral partnerships.

*This can be achieved through a combination of public health measures, such as rapid identification, diagnosis and management of the cases, identification and follow up of the contacts, infection prevention and control in health care settings, implementation of health measures for travelers, awareness-raising in the population and risk communication.

PREPAREDNESS AND RESPONSE

• To view all technical guidance documents regarding COVID-19, please go to this webpage.
  • WHO is working closely with International Air Transport Association (IATA) and have jointly developed a guidance document to provide advice to cabin crew and airport workers, based on country queries. The guidance can be found on the IATA webpage.
    
  • WHO has been in regular and direct contact with Member States where cases have been reported. WHO is also informing other countries about the situation and providing support as requested.
    • WHO has developed interim guidance for laboratory diagnosis, advice on the use of masks during home care and in health care settings in the context of the novel coronavirus (2019-nCoV) outbreak, clinical management, infection prevention and control in health care settings, home care for patients with suspected novel coronavirus, risk communication and community engagement and Global Surveillance for human infection with novel coronavirus (2019-nCoV).
      
    • WHO is working with its networks of researchers and other experts to coordinate global work on surveillance, epidemiology, mathematical modelling, diagnostics and virology, clinical care and treatment, infection prevention and control, and risk communication. WHO has issued interim guidance for countries, which are updated regularly.
    • WHO has prepared a disease commodity package that includes an essential list of biomedical equipment, medicines and supplies necessary to care for patients with 2019-nCoV.
    • WHO has provided recommendations to reduce risk of transmission from animals to humans.
      • WHO has published an updated advice for international traffic in relation to the outbreak of the novel coronavirus 2019-nCoV.
        
      • WHO has activated the R&D blueprint to accelerate diagnostics, vaccines, and therapeutics.
        • WHO has developed online courses on the following topics: A general introduction to emerging respiratory viruses, including novel coronaviruses (available in French, Chinese, Spanish, and Portuguese); Critical Care of Severe Acute Respiratory Infections; and Health and safety briefing for respiratory diseases - ePROTECT (available in French); Infection Prevention and Control for Novel Coronavirus (COVID-19); Critical Care Severe Acute Respiratory Infection
          
        • WHO is providing guidance on early investigations, which are critical to carry out early in an outbreak of a new virus. The data collected from the protocols can be used to refine recommendations for surveillance and case definitions, to characterize the key epidemiological transmission features of COVID-19, help understand spread, severity, spectrum of disease, impact on the community and to inform operational models for implementation of countermeasures such as case isolation, contact tracing and isolation. Several protocols are available here: https://www.who.int/emergencies/diseases/novel-coronavirus-2019/technical-guidance/early-investigations One such protocol is for the investigation of early COVID-19 cases and contacts (the “First Few X (FFX) Cases and contact investigation protocol for 2019-novel coronavirus (2019-nCoV) infection”). The protocol is designed to gain an early understanding of the key clinical, epidemiological and virological characteristics of the first cases of COVID-19 infection detected in any individual country, to inform the development and updating of public health guidance to manage cases and reduce the potential spread and impact of infection.

RECOMMENDATIONS AND ADVICE FOR THE PUBLIC

If you are not in an area where COVID-19 is spreading, or have not travelled from an area where COVID-19 is spreading, or have not been in contact with an infected patient, your risk of infection is low. It is understandable that you may feel anxious about the outbreak. It’s a good idea to get the facts from reliable sources to help you accurately determine your risks so that you can take reasonable precautions (See Frequently Asked Questions). Seek guidance from WHO, your healthcare provider, your national public health authority or your employer for accurate information on COVID-19 and whether COVID-19 is circulating where you live. It is important to be informed of the situation and take appropriate measures to protect yourself and your family (see Protection measures for everyone).

If you are in an area where there are cases of COVID-19 you need to take the risk of infection seriously. Follow the advice of WHO and guidance issued by national and local health authorities. For most people, COVID-19 infection will cause mild illness however, it can make some people very ill and, in some people, it can be fatal. Older people, and those with pre-existing medical conditions (such as cardiovascular disease, chronic respiratory disease or diabetes) are at risk for severe disease (See Protection measures for persons who are in or have recently visited (past 14 days) areas where COVID-19 is spreading).
