Statistics by Country for Common cold

Incidence (annual) of Common cold:

62 million cases (NIAID); 23.6 per 100 (NHIS96); estimated 1 billion colds in the USA annually; Children get 6-10 yearly, adults 2-4 yearly; over 60's less than 1 a year.

Incidence Rate for Common cold: approx 1 in 4 or 22.79% or 62 million people in USA [about data] Extrapolation of Incidence Rate for Common cold to Countries and Regions: WARNING! EXTRAPOLATION ONLY. NOT BASED ON COUNTRY-SPECIFIC DATA SOURCES. The following table attempts to extrapolate the above incidence rate for Common cold to the populations of various countries and regions. As discussed above, these incidence extrapolations for Common cold are only estimates and may have very limited relevance to the actual incidence of Common cold in any region:

About extrapolations of prevalence and incidence statistics for Common cold:

WARNING! EXTRAPOLATED STATISTICS ONLY! Not based on data sources from individual countries. These statistics are calculated extrapolations of various prevalence or incidence rates against the populations of a particular country or region. The statistics used for prevalence/incidence of Common cold are typically based on US, UK, Canadian or Australian prevalence or incidence statistics, which are then extrapolated using only the population of the other country. This extrapolation calculation is automated and does not take into account any genetic, cultural, environmental, social, racial or other differences across the various countries and regions for which the extrapolated Common cold statistics below refer to. The extrapolation does not use data sources or statistics about any country other than its population. As such, these extrapolations may be highly inaccurate (especially for developing or third-world countries) and only give a general indication (or even a meaningless indication) as to the actual prevalence or incidence of Common cold in that region. These statistics are presented only in the hope that they may be interesting to some people.

About prevalence and incidence statistics in general for Common cold:

The word 'prevalence' of Common cold usually means the estimated population of people who are managing Common cold at any given time (i.e. people with Common cold). The term 'incidence' of Common cold means the annual diagnosis rate, or the number of new cases of Common cold diagnosed each year (i.e. getting Common cold). Hence, these two statistics types can differ: a short disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
