Editor's Notes

  • Metagenomics - study of DNA or RNA sequence from a sample, mixture of more than one species
    Get a holistic picture
  • Reminder: the greatest th
  • Drain the swamps, oil the open water
  • Alameca County Mosquito Abatement
    CO2 traps
  • What do the sequences mean?
  • What do the sequences mean?
  • ...it’s from a Racoon! Presumably from a female mosquito who had just eaten a blood meal.
  • Viruses, many of them new. Many had multiple viral infections.
  • Xenosurveillance is possible: tracking the pathogens of animals using flying syringes.

  • Four viruses. One in china, one in Guadaloupe, two in california.
  • Clearview AI
  • This was a complex collaboration. Capacity now being used. Senjuti repurposed to respond to Dengue outbreak.
