Aerosol transmission is possible at high concentrations in confined spaces, according to the 6th edition of the COVID-19 diagnosis and treatment plan issued by China's National Health Commission.
Researchers believe COVID19 spreads mainly from person to person among close contacts through respiratory droplets produced when infected person coughs or sneezes. People are likely most contagious when they are most symptomatic (the sickest).
Testing for novel coronavirus (2019-nCoV) is indicated for patients who have:
• Travelled to (including transit through) mainland China in the 14 days before the onset of illness OR
• Have had contact in 14 days before illness onset with a confirmed case of 2019-nCoV AND
• Presented with fever OR acute respiratory infection (e.g. shortness of breath or cough)
Finding a vaccine against the #COVID19 could prevent a worldwide pandemic, although few expect an immediate breakthrough.
Contact your local pathology collection service to check they are able to take specimens from mildly unwell patients. Sicker patients should be referred to the local ED, but call ahead.
