The Emerging Risks Team at Lloyd’s has been looking at the economic and insurance impacts of pandemics and published a report into the possible insurance impacts of a pandemic (pdf) in 2008, which was also summarised in this recent CII think piece (pdf) .   

The current strain of flu that’s causing concern is of the H1N1 type; different to the H5N1 strain (or ‘bird flu’) that made the news several years ago.  The new strain is from a mixture of a swine virus, human flu and, in fact, bird flu.

According to the World Health Organization the majority of people will not have immunity unless they work with pigs.  Once a strain is isolated work on a vaccine can begin but this is likely to take several months to prepare. 

In the meantime antivirals (which help to suppress the full effect of the virus) can be prescribed; it appears that oseltamivir and zanamivir are effective.  A key concern is that a virus will have immunity to antivirals; but at the moment this appears not to be the case, which is fortunate.

The current WHO ‘preparedness phase’ has now been raised to level 4.  The WHO is not recommending travel or trade restrictions.  They have already concluded that containment of the outbreak will not be possible because it has already been identified in many locations. They stress that a pandemic is not inevitable but that it is now more likely.

The excellent on line encyclopedia wikipedia once again shows its worth with an article  that shows suspected cases around the world. These are being mapped live (below) and include unconfirmed cases ranging from the US, UK, Spain to New Zealand.

Note that only 45 cases have been laboratory confirmed with another 1807 cases only “influenza like”.  According to the Centres For Disease Control and Prevention there are small number of confirmed cases from the east to west coast of the US (see graphic).

Restricting the view to just Mexico we see 152 deaths out of 2761 cases, which is appears to be a “case fatality rate” of over 5% (compared to 2.5% for the 1918 “Spanish flu” virus which killed tens of millions, though lower than bird flu which is still at a worrying 60%). 

The case fatality is the percentage of people who are ill with the flu who go on to die from it.  It is likely that a number of cases are unreported (whereas deaths are likely to be tracked accurately) so the true case fatality rate is probably lower than the basic statistics suggest; time will tell.  As you can expect there is some conflicting information on numbers with wikipedia showing 50 confirmed cases in the US and the CFC showing 40.

In the event of a major pandemic the insurance industry will potentially have to cope with an variety of claims, while it is still reeling from its own business continuity problems. Life and health insurers will be directly impacted but less immediately obvious losses could arise, from medical malpractice to event cancellation.

One of the key issues raised is that a major pandemic is thought likely to cause a global recession – given the current financial state of the world’s economy a pandemic could not be worse timed.  At present however, there is good reason to hope the impact of this flu will be manageable; we will continue to monitor the situation.
