Scenario B

Disaster has struck - hard on the heels of the COVID-19 pandemic, another disease outbreak has hit your fair city, Baltyre. Residents are outraged and worried. There have already been 20 deaths.

The cause of the outbreak appears to be Influenza A virus. (Please refer to the WHO Influenza 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 (Queen’s College)
  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 Baltyre
  9. Epidemiologist from the local university, an expert on influenza virus A 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, Baltyre. 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 outraged to hear about this new pandemic in Baltyre. There seems to be no end to the suffering that pandemics inflict on our city in these days.

I wish that your office is going to do something about all of the poor people dying at once.

Yours sincerely,

Subject: Pandemic Disaster for Businesses

Dear Provost,

This new pandemic in Baltyre has the potential to ruin our businesses. I run a records shop on the high street and almost literally went bankrupt due to COVID.

I hope you realise that you need to put businesses first now - we were unfairly forced to bear the costs of the last pandemic.

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

Respectfully,
Graham (Jewels, proprietor)

Subject: Stop This Madness

Dear Provost,

I dread 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.

You must not allow the city to suffer through another round of lockdowns, face-masks, and other punitive restrictions that destroy people’s lives.

Respectfully,
Eleanor (a concerned voter)

Dear Provost,

I have just learned that my my gran has passed away due to the new pandemic in Baltyre. You cannot begin to imagine the grief that we are feeling.

You cannot begin to imagine the grief that we are feeling.

I don’t understand why we haven’t learned how to deal with pandemics better, after all our experiences with COVID-19, I don’t understand how this could have happened.

Kind regards,

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

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