Fig. 4From: Limited effect of reducing pulmonary tuberculosis incidence amid mandatory facial masking for COVID-19Correlation between TB and COVID-19 incidences stratified by region. Spearman’s rank correlation coefficients were calculated. The regions with low incidences of COVID-19 (e.g., the Kao-Pin region) exhibited high incidences of TB. Thus, the COVID-19 prevention measures may not be effective in preventing TB transmissionBack to article page
