Flu bad, MERS a diversion?

In an "Infection hot topic" article in Clinical Microbiology and Infection, the Editor, Prof. Didier Raoult writes of the importance of not letting our excessive pride or self-confidence drive our desire to understand a rare and poorly transmissible (slowly-growing epidemic?) virus like the Middle East respiratory syndrome coronavirus (MERS-CoV) and distract us from "real infectious disease epidemics that are well known" at times of mass gatherings like the Hajj.

Because why not?

He notes that the recommendation for influenza vaccination during the recent Hajj probably prevented thousands of influenza cases and that 9% of returning French pilgrims returned an influenza virus positive throat sample. An example of some good communication then.

I wasn't aware that the scientific press, World Health Organization or governments had dropped any other balls in order to give MERS the attention any potentially new human pathogen, with or without pandemic potential, well and truly deserves.

I guess in hindsight, it might look like a lot of wasted effort went into MERS-related reporting. Readers of this blog would be aware of my own opinion on that matter - not nearly enough effort has gone into solving a number of questions about the MERS-CoV and certainly not enough data has been described and reported to make it easy to track and present new cases.

Far from being distracted, the developed nations have continued their fight against flu (so long as their governments aren't shut down), reporting heavily on it and other vaccine preventable diseases that are reappearing in the population (measles and polio for example). Many science communicators of all types in many locations around the world have also been discussing and describing in detail the oncoming wave of antibiotic resistant bacteria and many other viral and bacterial pathogens that can be considered rare depending, on the denominator you choose at the time. SARS-CoV infections were pretty rare (~8,200 confirmed cases) but the social, economic and healthcare impact of that little outbreak was incredibly disproportionate. Or perhaps it was perfectly proportionate? Remembering the SARS outbreak began in the dark without suitable coverage and communication to illuminate the early stages. 

What is the evidence that reporting on MERS has displaced any other efforts to monitor, debate or describe more endemic human infectious diseases?

Thankfully Prof. Raoult didn't call out the scientific community who are working hard to add new knowledge about "rare" human infections; work that will hopefully ensure they stay as rare as possible, for as long as possible if they are not halted at the source forever. 

I'm personally in no rush to read the bazillion Editorials that will follow in the wake of a pandemic due to infection by MERS-CoV, H7N9 or any other viruses with "little known effect on the human population".

Hindsight can be a harsh mistress but communication fosters preparedness.
