Covid-19 and Kids
My primary interest in starting this site was to try to understand the risk Covid-19 poses to kids. Here are links to studies underlying news headlines you may have seen.
- SARS-CoV-2 Transmission and Infection Among Attendees of an Overnight Camp — Georgia, June 2020
A camp in Georgia was associated with 260 cases among campers, staff and trainees. (My summary of the study)
- Association Between Statewide School Closure and COVID-19 Incidence and Mortality in the US (July 29, 2020)
One thing that is key to slowing the spread of this virus is understanding how people are infected. Being indoors with someone infected seems to be a much higher risk than being outside.
- Evidence for probable aerosol transmission of SARS-CoV-2 in a poorly ventilated restaurant (April 22, 2020)
This is an analysis of an outbreak tied to a restaurant in China in which people in the airstream of an air conditioner near an infected individual were infected, but not people at adjacent tables who were not in the airstream.
- Coronavirus Disease Outbreak in Call Center, South Korea (March 2020)
This is an analysis of who became infected at a call center and where their workstation was relative to a worker with the first confirmed case of Covid-19.
- High SARS-CoV-2 Attack Rate Following Exposure at a Choir Practice — Skagit County, Washington, March 2020
A detailed report on a super spreader event at an indoor choir practice.
- Outdoor Transmission of SARS-CoV-2 and Other Respiratory Viruses, a Systematic Review (November 29, 2020)
Overview of previous studies on transmission of SARS-CoV-2 and other viruses that confirms the belief that risk of transmission is lower outdoors.
- Evidence of Long-Distance Droplet Transmission of SARS-CoV-2 by Direct Air Flow in a Restaurant in Korea (November 23, 2020)
A study that seems to confirm indoor transmission over long distances depending on airflow. In this specific case, a patient was infected in a Korean restaurant from about 21′ away with only about 5 minutes of exposure.
How can we reduce transmission of SARS-CoV-2 without completely shutting down? These studies shed some light on our options.
- Effectiveness of surgical masks against influenza bioaerosols (March 2013)
This is a study about the effectiveness of masks against the flu, so if SARS-CoV-2 has similar transmission routes as the flu, this could give us some idea of how effective masks are for reducing transmission.
- Masks Do More than Protect Others during COVID-19: Reducing the Inoculum of SARS-CoV-2 (August 2020)
This is an analysis of whether reducing viral load can reduce transmission or result in a milder case of disease and what role cloth masks play in this theory.
It is common to hear people say that suicide rates are up during shut downs ordered due to the pandemic. However, this does not appear to be the case.
- Real-time suicide mortality data from police reports in Queensland, Australia, during the COVID-19 pandemic: an interrupted time-series analysis – The Lancet Psychiatry
Comparison of suicide rates before and after the pandemic declaration show no evidence of a rise during the pandemic.
