Scenario D

Disaster has struck - hard on the heels of the COVID-19 pandemic, another disease outbreak has hit your fair city, Rosblane. Residents are outraged and worried. There have already been 22 deaths.

The cause of the outbreak appears to be Campylobacter jejuni. (Please refer to the WHO Campylobacter Fact Sheet for more information about the pathogen.)

Each member of your group will play one of the following roles as you attempt to tackle the disease outbreak and save your city:

  1. Provost (head of the city council)
  2. Representative from a national public health org. (Public Health Scotland)
  3. Epidemiologist (on secondment from Public Health Scotland)
  4. Director of the city’s main hospital (North Shore)
  5. City planner/civil servant
  6. Microbiologist (working in one of the NHS Scotland clinical labs)
  7. Public communications expert (past and current sci comm campaigns)
  8. Doctor at a major surgery in Rosblane
  9. Epidemiologist from the local university, an expert on Campylobacter transmission

You must work together, using the information that has been provided for you in the attached information packets, and decide what action(s) should be taken to control the outbreak currently plaguing your city, Rosblane. Your actions should be evidence-based – use the peer-reviewed literature to decide on measures that will stop the pandemic in your scenario.

Your action points may include directives to gather more information (e.g., contact tracing of current cases, microbiological testing of food/water, etc.), or specific directives (e.g. public health measures, non-pharmaceutical interventions, etc.). Use the data/expertise of all group members. Be clear, concise, and specific.

You may choose to include mathematical modeling as part of your decision making (for example, using an epidemic calculator or other models); if you do so, you should provide details of your modelling and predictions when you submit your group’s pro forma.

You should submit 3-5 specific actions to control the pandemic, using the workshop 3 pro forma (also available on MyPlace). Submit this by noon, Friday March 1st, via the submission link on MyPlace.

Dear Provost,

I am upset to hear about this new pandemic in Rosblane. Too many people have died and it is such a tragedy.

I hope very much that your office is going to do something about dreadful state of affairs immediately.

Kind regards,

Subject: Pandemic Disaster for Businesses

Dear Provost,

This new pandemic in Rosblane has the potential to devastate our businesses. I run a bookshop on the high street and virtually went bankrupt due to COVID.

You should be ashamed to think of all the businesses that have had to close because of the coronavirus measures this city took, and all of the people who lost their jobs.

I hope that your office is going to do something about all of the poor people dying immediately, keeping in mind the economic interests of businesses in our city and the fact that we cannot afford another lockdown.

Kind regards,
Ailidh (Jewels, proprietor)

Subject: Government Overreach

Dear Provost,

I fear that you and your office are going to use this new pandemic as yet another excuse for government overreach into citizens’ lives. The mental health consequences of the last pandemic were underappreciated, but very real - people suffered due to the lockdowns and children’s development was affected by the wearing of face masks and the closing of schools.

Please do not use this disaster as another opportunity for oppressive lockdowns and government control of our lives.

All the best,
Roman (a concerned voter)

Dear Provost,

I have just learned that my my niece has passed away due to the new pandemic in Rosblane. Words cannot begin to describe our loss.

The family are all devastated as you can surely imagine.

I hope that you will do everything you can to stop this pandemic so that no other families need to suffer this pain.

Best wishes,
Siobhan

Information Packet D3

You are an epidemiologist working for Public Health Scotland, sent to Rosblane to help with the Campylobacter outbreak.

A team of scientists working together have in a PHS lab have isolated and cultured Campylobacter jejuni (following standard procedures) from a number of patient samples taken during this outbreak; isolated Campylobacter jejuni DNA from these cultures; sequenced this DNA using an Illumina MiSeq platform; assembled the short paired-end reads; and compared these assemblies to the extant Campylobacter jejuni genome sequences available in the NCBI databases. The results of these experiments are summarised in the table below.
