Mean SIR curves from the simulation.

Blue, red and green represent susceptible, infectious, and removed counts respectively. Darker colours represent the winter, lighter colours monsoon and summer. Lines are the mean of 50 runs on a population of 10,000 for each season. (TIF)</p

Occupations and employment outside the home.

(A) Percentages of males and females classed as unemployed outside the home. (B) Distribution of total contacts for both employed and unemployed. Solid line represents a gaussian KDE. Note the longer tail on the distribution for employed respondents. (C) Frequencies of occupations among the respondents of the survey. (TIF)</p

Age-stratified infectious curves from the simulation.

Mean number of infectious people across 50 simulations for every season who belong to a particular age category. Brown, red and orange represent winter, summer and monsoon seasons respectively. Significant difference across seasons is observed in the 50–59 category. (TIF)</p

Number of contacts by season and gender.

Gender-stratified heat-maps representing the average number of contacts reported between two age categories (Males in blue, females in red). Brighter colours imply a pair of categories with a high number of contacts. (TIF)</p

Age stratified rates used in the simulation.

r_sus is relative susceptibility, and is multiplied to the value of a target’s beta. p_symp represents the probability of showing symptoms, p_severe the probability of displaying severe symptoms given the person is infected, and p_deceased the probability of death given the person has severe symptoms. Rates taken from the Covasim model developed by Kerr et al.33 (PDF)</p

Age stratified comparison of total contacts reported in each season.

(A), (B), (C) Age stratified number of contacts in winter, summer and monsoon respectively. Pink dots in the boxplots represent the mean values. (D), (E), (F) Heatmaps showing p-values from Dunn’s post-hoc test for winter, summer and monsoon respectively. Dark regions represent pairs of age categories for which the difference in the number of contacts is not significant (p>0.05). (G) Comparison of number of contacts for age categories across the three seasons. Pairs of age categories with a significant difference in contacts (Nemenyi post-hoc test, p<0.05) are marked with an asterisk symbol.</p

Proportion of physical contacts.

(A) Barplots of the proportion of contacts reported to involve physical touch for all three waves, stratified by the duration of the contact. (B) Proportion of physical contacts for all three waves stratified by the frequency of which the respondent met the contact. (TIF)</p

Contact setting and proportions of physical contacts.

(A), (B) The number of group and total contacts reported inside and outside the home, for each season. (C), (D) The durations (in person-hours) of group and total contacts reported inside and outside the home, for each season. (E) The mean proportion of physical contacts across all respondents observed at every location for each season. Black horizontal lines represent 95% confidence intervals. Significant differences in proportions of physical contacts at each location are represented with asterisks.</p

Gender stratified number of contacts.

(A) Boxplots of the number of contacts that occurred at home reported by males (blue) and females (red). (B) Boxplots of the number of total contacts reported to have occurred outside the home. Note that the upper y limit has been truncated to match that of (A). (C) Boxplots of the number of contacts stratified by gender and age category, across every wave. (TIF)</p
