Reacción a "Reactions: one in eight deaths in 2019 were linked to bacterial infections"

This article is of interest as it measures for the first time the impact of bacterial infections globally. The results are very impressive, as the number of deaths related to these infections in the year of the study, 2019, was higher than the number of deaths from covid-19 after three years (7.7 million vs. 6.6 million) and the second leading cause of death that year. 

The methodology is subject to error and this may be higher for two reasons: 

• The source for European countries is the TESSY programme, which does not provide individual patient data and does not represent, in the case of Spain, all centres, so these are estimates of the number of infections and on them estimates of the number of deaths calculated by a risk coefficient.  
• This risk of error in the data is appreciable when we see that the main syndrome causing death in S. aureus infections is respiratory tract infection, which is not the case in clinical practice.
