In an article published in Medscape in August 2020, it discussed a study that had been conducted on the spread of COVID-19. Yes, there have been a gazillion studies conducted and many have differing opinions outcomes. The goal of sharing these studies is to keep you informed of the scientific research being conducted throughout the world to find a cure for this virus. What was interesting about this study was their focus on “normal speech” and the spread of the virus.

Normal human speech emits droplets capable of carrying SARS-CoV-2 that causes COVID-19, researchers said. The droplets lingered in the air for up to 14 minutes which could help explain why the disease spreads so rapidly. Previous research showed these droplets can contain respiratory pathogens such as M tuberculosis, flu viruses, and measles virus, so could they also carry SARS-Co-V-2?

Here are the clinical implications of the study:

  • Droplet nuclei released by speaking loudly are of sufficient size and remain airborne long enough to be inhaled by others and trigger a new SARS-CoV-2 infection, according to a study by Stadnytskyi et al.
  • Findings of a separate study by Zang and colleagues highlighted the intestine as a potential site of SARS-CoV-2 replication, which may contribute to local and systemic illness and overall disease progression but make fecal-oral transmission of SARS-CoV-2 unlikely.
  • Implications for the Healthcare Team: The findings reinforced the need for masking, social distancing, and avoidance of gatherings in enclosed spaces with poor ventilation and low humidity

There you have it, not so different from previous studies or studies having been conducted more recently. Bottom line, mask up, social distance, avoid gatherings in enclosed spaces, and wash your hands frequently! Stay the course, stay strong, stay well, and stay tuned!
