Carlo Urbani, the director for the World Health Organisation (WHO), subsequently killed by the disease, then termed it SARS.
The case definition of SARS or atypical pneumonia is a fever with a temperature higher than 100. ... The WHO currently declares a mortality rate of 15% from SARS, compared with the initial underestimate of 4%. ...

Phylogenetic studies of the viral proteins specify no correlation between the virus and any of the three identified categories of coronavirus. It characterises a fourth genre of coronavirus and is referred to as SARS-CoV. ...

SARS is concurrent with increased macrophage activity in the lung tissues and epithelial-cell proliferation.
