Title: Correlation between universal BCG vaccination policy and reduced morbidity and mortality for COVID-19: an epidemiological study Document date: 2020_3_28
ID: 35meen0h_13
Snippet: The countries with low-income levels (18) reported few number of cases of COVID-19 per million inhabitants: 0.32 ± 0.09. However, the issue of underreporting might be more critical for estimating the number of cases and we have excluded the low income countries from further analysis. Middle high and high-income countries that have a current universal BCG policy (55 countries) had 59.54± 23.29 (mean±s.e.m) cases per million inhabitants (see Fig.....
Document: The countries with low-income levels (18) reported few number of cases of COVID-19 per million inhabitants: 0.32 ± 0.09. However, the issue of underreporting might be more critical for estimating the number of cases and we have excluded the low income countries from further analysis. Middle high and high-income countries that have a current universal BCG policy (55 countries) had 59.54± 23.29 (mean±s.e.m) cases per million inhabitants (see Figure 3 ). Consistent with a role of BCG in slowing spread of COVID-19, middle high and high income countries that never had a universal BCG policy (5 countries) had about 4 times the number of cases per million inhabitants, with 264.90± 134.88. This difference between countries was significant (p=0.0064, Wilcoxon rank sum test), suggesting that broad BCG vaccination along with other measures could slow the spread of COVID-19.
