WHO advice for international traffic in relation to the outbreak of the novel coronavirus 2019-nCoV with Dr Carmen Dolea, Head, IHR Secretariat at the World Health Organization
So far, the main clinical signs and symptoms reported in this outbreak include fever, difficulty in breathing, and chest radiographs showing bilateral lung infiltrates. As of 27 January 2020, human-to-human transmission has been confirmed largely in Wuhan city, but also some other places in China and internationally. Not enough is known about the epidemiology of 2019-nCoV to draw definitive conclusions about the full clinical features of disease, the intensity of the human-to-human transmission, and the original source of the outbreak.
International travellers: practice usual precautions
Coronaviruses are a large family of respiratory viruses that can cause diseases ranging from the common cold to the Middle-East Respiratory Syndrome (MERS) and the Severe Acute Respiratory Syndrome (SARS). In case of symptoms suggestive of acute respiratory illness before, during or after travel, the travellers are encouraged to seek medical attention and share travel history with their health care provider.
Public health authorities should provide to travellers information to reduce the general risk of acute respiratory infections, via health practitioners, travel health clinics, travel agencies, conveyance operators and at Points of Entry. Novel Coronavirus (2019-nCoV) advice for the public published on the WHO website contains WHO standard recommendations for the general public to reduce exposure to and transmission of a range of illnesses, to protect yourself and others from getting sick, to stay healthy while travelling.
WHO technical guidance on surveillance and case definitions, laboratory guidance, clinical management for suspected novel coronavirus, home care for patients with suspected novel coronavirus, infection prevention and control, risk communications, disease commodity package, and reducing transmission from animals to humans is available on the WHO website.
