Thanks to everyone who joined the call today! A really fascinating discussion - I definitely recommend listening to the podcast if you have a spare moment. Some ideas that were batted around:

  1. Is it possible to control TB and DR TB without fixing underlying weak health systems? Is $1 million better spent as adding 1% to a primary health care system, 10% to a TB control program, or 50% to a TB research budget?
  2. There may be a role for some sort of generalizable model in settings of highly mobile, hotspot-oriented populations, to evaluate in a generic sense what types of interventions are likely to be most effective.
  3. We took an informal poll of the question, "among people who have prevalent MDR TB in Somalia, how many were primarily infected with a Rif-resistant strain?" Despite having a fair amount of collective TB knowledge in the room, there was not consensus on this...though most people felt that the number was probably over 50%. If this is true, then simply treating drug-susceptible TB (as is the #1 priority from the WHO) is unlikely to rapidly fix an MDR epidemic.
  4. Coming up with the data that would be necessary to populate a better model of MDR transmission in a place like Somalia...is incredibly hard!! We had a hard time even thinking of where one would start with that. It's not just the tricky natural history of TB, but also the lack of infrastructure and routine data in such settings.
  5. But despite all this, it's clear that TB epidemics, and especially MDR epidemics, are concentrated in areas of poor infrastructure. It's fascinating to think of why this is - a couple of hypotheses that were advanced during our discussion were that people in places like Somalia are more likely to have access to drugs like INH/RIF only (since simply interrupting treatment is not as likely to generate resistance), or that MDR requires a certain threshold of malnutrition/crowding/etc. to transmit - and that such a threshold may be much easier to reach in a place like Somalia.

Thanks again to everyone for a really fascinating discussion!! Our next call will be at the same time (2pm Eastern) on April 21st - I look forward to it!!

Thanks to those who joined us for a very nice discussion today, and to Andrew for leading the charge! A couple of quick summary points:

As usual, we'll work to get the podcast up soon on the website (link here), under past discussions. I will be in touch in January with plans for the new year - we have to discuss internally here at Hopkins how we want to integrate these into our own team meetings (and Tuesday at noon will fall on the time that I have instructors' meetings for the course I am teaching).

Thanks to each of you for making this a great year for our modeling calls!! I certainly have learned a lot from each of you. I hope you all have a wonderful holiday!!

Thanks to everyone who participated in our call yesterday! While I'm not sure there were any groundbreaking conclusions, as one person said, sometimes it's nice just to listen. I was struck by the convergence of themes from so many people - the difficulty of staying up-to-date in diverse fields, the challenge of maintaining respect across quantitative experts and policy experts (so that one doesn't feel either dumb or out-of-touch), the importance of maintaining fora where people can come together and learn from each other, the friction between personal aspirations and a system that is set up with different values in mind. I certainly enjoyed hearing people's perspectives.

The podcast is up here, for those who are interested to listen.

I hope that everyone has a wonderful Thanksgiving, and I will be in touch next month! Our next call will be on December 16, again at noon Eastern time.
