    Relationship between monthly mean temperature (red line) and incidence per 100,000 persons admitted with necrotizing soft tissue infections (black bars) from 2001 to 2015. JA, January; AP, April; JL, July; OC, October. Although no significant association was found year-to-year, fewer cases were noted in the fall and winter months.

    Relationship between mean monthly temperature and incidence of necrotizing soft tissue infections per 100,000 persons demonstrating a clear trend towards more cases in months with higher temperatures (p<0.01).

  • Figure 3
    Figure 3

    Relationship between mean monthly humidity and monthly incidence of necrotizing soft tissue infections per 100,000 persons. An inverse relationship was observed (p=0.005).
