get_template_data {imprinting} | R Documentation |
get_template_data()
returns a tibble showing the fraction of influenza A cases caused by subtype H1N1, H2N2, or H3N2 in each year from 1918-1996. These data are country-independent. Country-specific data are only available from 1997 on.
For years 1918-1976 only one influenza A subtype circulated, so all fractions are 0 or 1.
From 1977-1996 H1N1 and H3N2 both circulated. get_template_data()
reports the fraction of influenza A-positive specimens of each subtype observed in US flu surveillance. See Thompson et al. JAMA, 2003, Table 1.
Country-specific data from WHO Flu Mart will be appended to this template in later steps.
get_template_data()
A tibble with the following columns:
year
A/H1N1
, A/H2N2
, and A/H3N2
show the fraction of influenza cases caused by each subtype.
A
= A/H1N1
+ A/H2N2
+ A/H3N2
B
is a placeholder for future calculate of influenza B imprinting probabilities, which currently contains NA
.
group1
and group2
show the fraction of cases caused by group 1 subtypes (H1N1 and H2N2), or group 2 (H3N2).
