Outbreak update

What Insurers Should Learn

The WHO declared the Brazil outbreak a Public Health Emergency of International

Concern in February 2016.

Some scientists have called for the cancellation of the Summer Olympics to be

held in August in Rio de Janeiro.

Does this mean Zika is a significant pandemic threat?

Zika virus is transmitted through the bite of an infected Aedes aegypti mosquito or sex.

Spread through blood transfusion is a strong possibility.

Large numbers of Zika virus infections have been reported in Brazil

since May 2015.

cases by December 2015 (number likely underreported due to the

mild nature of clinical symptoms).

Estimates put the total at

500,000 to 1.5 milliOn

Zika infection in adults usually causes short-lasting symptoms associated with mild fever.

But it can cause Guillain-Barré syndrome (GBS) – a rare and serious neurological disorder.

Zika is also a cause of microcephaly – a devastating developmental condition in newborns.

500,000 visitors

are expected in Brazil for the Summer Olympics.

But calling the Olympics off, or moving them, is unlikely to significantly influence the international spread of Zika.

After all, Brazil is only

1 of nearly 40 countries affected by the current outbreak

in the Americas.

Yet accidentally transporting home an infected insect could introduce Zika to new areas.

Infected travellers could return with Zika in their blood and pass it on through mosquito bites or sex.

What does this mean for insurers?

Although Zika infection is unlikely to cause long-term disability in adults,

Projections suggest that Zika could lead to a moderate increase in total disability claims for a

limited period of time in heavily affected areas.

20% are left severely

disabled.

5% of those infected

with GBS die

The recent rise in microcephaly is clearly linked to Zika.

Insurers may think it prudent to exclude benefits for congenital conditions in unborn children.

Thankfully, there are some

signs that the worst might be over in Brazil.

Epidemiological reports show a decline in the number

of newly reported cases (confirmed and not

confirmed) of microcephaly.

The proportion of confirmed microcephaly cases in the analysed cases has been declining.

In many ways, Zika is yet another test of what could happen in the event of a sustained viral attack on global public health.

So it’s about being prepared.
