Extended Data Fig. 5: Sensitivity analysis on household related factors in households with high sampling rates.

Sensitivity analysis on how household composition (a, b), infection history (c) and immunity (d) impact risk of infection in households where more than 80% of samples are recorded (n = 6435). (a) Odds ratio for the number of total individuals in various age bins (newborn [NB], from 1–5 years old, from 5 to 18, and those 18 years or older [GE18]) defined at the time of the post-interval sample. (b) Odds ratio for the number of males and females of various age bins (newborn [NB], from 1–5 years old, from 5 to 18, and those 18 years or older [GE18]) defined at the time of the post-interval sample. (c) Previous interval’s attack rate (AR) and subsequent odds ratio of infection risk relative to having no infections in the previous interval. (d) Geometric mean of DENV HAI titers for the rest of the household and subsequent odds ratio of infection risk relative to having an average household HAI titer under 40. All models are adjusted for household random effects, individual pre-interval titers, as well as the year and month of post-interval sample. The vertical dashed line represents an aOR of 1 (no significant impact on risk).
