Eligibility Criteria

Inclusion

  • Age \>=1 year (as children \<1 year may not be able to take oral probiotics)
  • Household contact of someone diagnosed with COVID-19
  • Willingness to stop taking other probiotics or to not take any other probiotic while on LGG/placebo (taking a probiotic at the time of screening will not be considered a reason for exclusion. However, subjects will be asked to stop taking their probiotic if they enroll on the study).
  • Access to e-mail/internet to complete electronic consent via REDCap

Exclusion

  • Symptoms of COVID-19 at enrollment, including:
  • Fever
  • Respiratory symptoms
  • GI symptoms
  • Anosmia
  • Ageusia -\>7 days since original patient associated with household contact was diagnosed with COVID-19
  • Taking hydroxychloroquine or remdesivir for any reason (as this would have the potential to decrease the expected rate of COVID-19 in this population and affect our power and sample size calculations)
  • Enrolled in a COVID-19 prophylaxis study (as this would have the potential to decrease the expected rate of COVID-19 in this population and affect our power and sample size calculations)
  • Any medical condition that would prevent taking oral probiotics or increase risks associated with probiotics including but not limited to:
  • Inability to swallow/aspiration risk and no other methods of delivery (e.g., no G/J tube)
  • Increased infection risk due to immunosuppression due to:
  • Chronic immunosuppressive medication
  • Prior organ or hematopoietic stem cell transplant
  • Known neutropenia (ANC \<500 cells/ul)
  • HIV and CD4 \<200 cells/ul
  • Increased infection risk due to endovascular due to:
  • Rheumatic heart disease
  • Congenital heart defect,
  • Mechanical heart valves
  • Endocarditis
  • Endovascular grafts
  • Permanent endovascular devices such as permanent (not short-term) hemodialysis catheters, pacemakers, or defibrillators
  • Increased infection risk due to mucosal gastrointestinal due to:
  • Gastroesophageal or intestinal injury, including active bleeding
