This video is primarily ‘historically informative’ and just defines the virus itself – so I considered it educational backgrounding on the CORONA VIRUS (CoV). BUT GENERALLY SPEAKING WHEN IT COMES TO THE DISSEMINATION, SPREAD, CASE COUNTS, THERAPIES and CURRENT STATUS OF THE LETHALITY – BEWARE!! 👀💀

A new novel virus identified from humans 29th December 2019, 2019-nCoV Human respiratory viral infections Cold often caused by rhinovirus Influenza (flu) caused by influenza virus.
Coronaviruses virion CoV is a single stranded RNA Protein envelope (protein shell or capsid) Crown shaped virions Less than 100 nm Coronaviruses are zoonotic MERS Middle East Respiratory Syndrome, 2012 SARS Severe Acute Respiratory Syndrome, 2003 Novel previously unidentified in humans, 2019 – nCoV Clinical features Fever 98% Cough 76% Myalgia or fatigue 44% Sputum production 28% Headache 8% Haemoptysis 5% Diarrhoea 3% Dyspnoea 55% Severe acute respiratory infection – pneumonia Acute respiratory distress syndrome.
Radiology Median duration from illness onset to dyspnoea 8·0 days Median time from onset of symptoms to first hospital admission 7·0 days Time from onset of symptoms to mechanical ventilation was 10·5 days Leucopenia less than 4 × 109/L 25% Lymphopenia less than 1·0 × 109/L 63% Transmission Direct from animals, vectors Human to human Droplet, nasal or mouth mucosa, eyes Coughs and sneezes spread diseases – over 2 metres Catch it – bin it – kill it Surfaces – hands – mucous membranes Virus contained in an envelope, so virus can stay dormant for 5 days Fomites Closed environments, less likely outside.
