It is believed to be transmitted through contact with the bodily fluids of an infected person, and it can also be spread through close contact with an infected animal. SARS has a fatality rate of around 10%, but it can be higher in certain groups such as the elderly and those with underlying health conditions.
9. influenza A (H1N1) –
