[ 3 ] [ 4 ] [ 5 ] Viruses are preserved in colder temperatures due to slower decomposition, so they linger longer on exposed surfaces (doorknobs, countertops, etc. ).
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.

[1] Summer temperatures in Europe were the coldest of any on record between 1766 and 2000, [2] resulting in crop failures and major food shortages across the Northern ...
