A cluster of cases of pneumonia that occurred in Wuhan, Hubei Province China during December 2019, were confirmed in early January 2020 as caused by a novel coronavirus (SARS-CoV-2). SARS-CoV2 may have originated from an unknown animal source, but is mainly transmitted from human to human by breathing in droplets from the nose or mouth of an infected person or by touching the infected droplets on surfaces, then touching the eyes, nose or mouth. National and international spread of this virus has resulted in COVID-19 cases being reported worldwide.
The most common symptoms of coronavirus (COVID-19) are recent onset of a new continuous cough or high temperature or a loss of, or change in, normal sense of taste or smell (anosmia). Symptoms range from mild to life threatening. Most cases report a mild illness, but some individuals will develop pneumonia causing shortness of breath and breathing difficulties. Those who are elderly or have underlying health problems are more likely to develop severe disease. There is a higher risk of infection and of severe disease in Black, Asian and Minority ethnic groups in the UK but the reasons for this are currently not clear.
There is currently no preventive vaccine (although new vaccines are under development with clinical trials ongoing). A number of treatments for COVID-19 are being used and trialled in hospital settings. Medical care aims to relieve and treat the symptoms. Those who develop symptoms of COVID-19 should self-isolate and arrange to have a test following Public Health England (PHE) stay at home guidance.
COVID-19 is transmitted through droplets of saliva or discharge from the nose when an infected person coughs or sneezes and direct or indirect contact with these secretions. In addition to respiratory secretions, other coronaviruses have been detected in blood, faeces and urine.
To reduce the risk of coronavirus infection all travellers should:
To reduce the risk of passing coronavirus to others, anyone with respiratory symptoms should:
Travellers currently in countries that are reporting cases of COVID-19 should follow local public health advice.
Current Foreign, Commonwealth and Development Office (FCDO) travel advice should always be checked along with advice regarding risk of disease which is available on our Country Information pages.
Individuals entering or returning to the UK are required to follow additional UK border measures which may include self-isolation for 14 days. See current UK border control guidance.
