“…Isolation and stay-at-home measures do not effectively protect essential workers, especially health care personnel, who have become infected and are dying at alarming rates [ 4 ]. Economic and other necessities limit how well and how long these isolation measures can be maintained, especially in poor countries and in poor communities such as slums and favelas [ 5 , 6 ]. As populations gradually try to get back to normalcy, reducing social distancing, and people in “non-essential professions” return to the workplace, they become more at risk for infection.…”

“…Due to the highly infective pandemic threat of COVID-19, several questions regarding prophylactic and therapeutic applications during medical and dental interventions, especially due to aerosols, have arisen. Notably dentists, dental hygienists and dental assistants represent a professional group, who is among at the greatest risk for exposure to bacteria and viruses, since the oral cavity holds a high potential of transmissibility and susceptibility to this and other infectious agents, especially, when aerosol producing instruments are used [1].…”

Quantitative measurements of aerosols from air-polishing and ultrasonic devices: (How) can we protect ourselves?

Aim To assess the distribution and deposition of aerosols during simulated periodontal therapy. Methods A manikin with simulated fluorescein salivation was treated by four experienced dentists applying two different periodontal treatment options, i.e. air-polishing with an airflow device or ultrasonic scaling in the upper and lower anterior front for 5 minutes, respectively. Aerosol deposition was quantitatively measured on 21 pre-defined locations with varying distances to the manikins mouth in triplicates using absorbent filter papers. Results The selected periodontal interventions resulted in different contamination levels around the patient’s mouth. The highest contamination could be measured on probes on the patient’s chest and forehead but also on the practitioner’s glove. With increasing distance to the working site contamination of the probes decreased with both devices. Air-polishing led to greater contamination than ultrasonic. Conclusion Both devices showed contamination of the nearby structures, less contamination was detected when using the ultrasonic. Affirming the value of wearing protective equipment we support the need for universal barrier precautions and effective routine infection control in dental practice.

“…COVID-19 is an emerging infectious disease that is spreading across the country of Brazil. People living in areas with precarious conditions of basic sanitation are often more vulnerable to this disease 11 . Here, we assessed the correlation between COVID-19 numbers/rates and basic sanitation in Brazil.…”

“…These sanitation features and the presence of several population clusters in Brazil may contribute to the uncontrolled increase in COVID-19 incidence and possible reinfections. In addition, these cluster areas host 11,425,644 citizens (6% of the Brazilian population), according to the 2010 population census 10,11 . The living conditions in subnormal agglomerations are still poor when facing the COVID-19 pandemic.…”

Introduction: Considering that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been detected in feces, this study aimed to verify a possible relationship between basic sanitation indices and coronavirus disease (COVID-19) numbers/rates. Methods: Data of COVID-19 cases registered in Brazil until May 28, 2020, and independent variables associated with basic sanitation were analyzed. Results: A significant correlation between the number of cases and sewage treatment index/population density was observed. In addition, COVID-19 incidence and mortality rates were significantly associated with the total water service index and lethality rate was significantly associated with the sewage treatment index. Conclusions: Precarious basic sanitation infrastructure may potentially increase the SARS-CoV-2 transmission in Brazil.
