SARS
Virus Variant MERS Spreading from Middle East
Saudi
Arabia reports four more deaths from MERS coronavirus
17
June, 2013
Thirty-three
people are dead from MERS, a coronavirus that the World Health
Organization (WHO) is calling a “threat to the entire world”.
MERS, for Middle East Respiratory Syndrome, is a newly discovered
virus that causes severe respiratory infection.There have been 58
laboratory-confirmed cases world-wide since the virus was discovered
last September. Saudi Arabia claims about half of all cases of MERS.
Some 30 people have died. Alarm bells are not over what has been MERS
has done, but for what it has the potential to do.
These
statistics were published by WHO on June 14. On June 15th, three new
cases and another death were advised, rendering daily WHO updates
instantly out of date. By the time this story is published, numbers
will rise.
By
June 17, Saudi Arabia has confirmed four more deaths.
The
bug is a variant of Severe Acute Respiratory Syndrome (SARS), a virus
that emerged in Asia over a decade ago. That disease spread rapidly,
infecting over 8,000 people and killing nearly 800 before
mysteriously disappearing.
Last
year, the first case of this new virus was recorded when a Saudi man
developed the infection and died. It was several months before a
second man was stricken. Concerns arose that transmission would
exponentially increase during the 2012 Hajj, when millions of Muslims
made pilgrimage to the Saudi holy city of Mecca, but no outbreak
occurred and alarm over the unnamed virus (simply called “SARS-like”)
quieted.
But
it’s back in the news with two known cases of Mecca pilgrims
falling fatally ill this year. In February, a British pilgrim died
after infecting two family members. In late May, a 66-year-old
Tunisian man died after returning from a pilgrimage, and two of his
children tested positive for the virus.
Last
month two new cases were reported in France. Patient #1 had traveled
to Dubai, became ill and was hospitalized in France, where his
hospital roommate picked up the bug. Cases have since been reported
in Tunisia, Qatar, the United Kingdom, Germany, Jordan, and the
United Arab Emirates.
Tough
talk and decisive action can be effective tools when dealing with
public health. So Margaret Chan, WHO secretary-general, grabbed a
microphone and boldly announced that the coronavirus circulating
mostly in the Middle East posed a “threat to the entire world.”
And
the news media took the bait. Is she overstating the threat?
Chan
from WHO was directly involved with the Asian SARS outbreak. She’s
experienced in corralling world attention to scary epidemics. A case
of “the girl who cried wolf”? Or a prudent early warning system
to incite sober attention to an unpredictable new virus with
far-reaching influence?
She
said, “We understand too little about this virus when viewed
against the magnitude of its potential threat. Any new disease that
is emerging faster than our understanding is never under control.
These are alarm bells and we must respond. The novel coronavirus is
not a problem that any single country can manage by itself.”
The
virus continues to spread into new countries, raising concern ahead
of the Islamic pilgrimage periods which will occur this summer and
autumn.
Most
of the victims suffered from underlying medical conditions. The WHO
says the virus spreads by means including interpersonal contact, and
possibly via airborne transmission between people in closed quarters.
It doesn’t appear to spread easily in communities at large, but
what about transmission between travelers in airports and planes?
Authorities
believe initial transmission of the virus was from animal to human,
but the animal source remains unidentified.
The
European Center for Disease Prevention and Control noted the many
unanswered questions about the Middle East-based virus, issuing a
statement saying, “It is unusual to have such a degree of
uncertainty at this stage in an outbreak.”
