COVID-19 pandemic: a new round of antibiotic resistance

In this article, we analyzed the problems associated with increasing antibiotic resistance, irrational use of antibiotics, and inadequate demand for them during the COVID-19 pandemic. Objective. Using the method of digital epidemiology, we analyzed the dynamics of the frequency of a specific request for antibiotics in pharmacies and hospitals. We used open data from Yandex (Wordstat.Yandex) and Google (Google Trends) collected on weekly basis for the Russian Federation. Results. The World Health Organization reports a growing problem of antibiotic misuse by some individuals and healthcare institutions during the COVID-19 pandemic. Extensive irrational use of antibiotics causes the development of antibiotic resistance by many microorganisms, including those circulating in hospitals (for example, ESKAPE group). Moreover, COVID-19 has led to an exponential increase in the use of biocides worldwide, potentially resulting in additional indirect pressure promoting the selection of antibiotic-resistant strains. The pandemic in Russia was marked by a significant increase in antibiotic sales in pharmacies (including systemic antibacterial agents) and purchases by healthcare institutions. Conclusion. Our findings demonstrate that the rapid spread of COVID-19 was associated with extensive consumption of antibiotics, which resulted in growing antibacterial resistance (number of circulating drug-resistant strains) and posed a threat to the national security. The COVID-19 necessitates the discovery of new effective treatments for this infection, as well as rational use of antimicrobial drugs. The implementation of surveillance of antibiotic consumption will help to identify changing trends in their use, combine efforts to solve problems related to antibiotics and drug resistance, and to ensure rational use of antimicrobials.
