A
new virus from the same family as SARS which sparked a global alert in
September has now killed two people in Saudi Arabia, and total cases
there and in Qatar have reached six, the World Health Organisation said.
The
UN health agency issued an international alert in late September saying
a virus previously unknown in humans had infected a Qatari man who had
recently been in Saudi Arabia, where another man with the same virus had
died.
On Friday it said in an outbreak update that it had registered four more cases and one of the new patients had died.
“The
additional cases have been identified as part of the enhanced
surveillance in Saudi Arabia (three cases, including one death) and
Qatar (one case),” the WHO said.
The
new virus is known as a coronavirus and shares some of the symptoms of
SARS, or Severe Acute Respiratory Syndrome, which emerged in China in
2002 and killed around a 10th of the 8,000 people it infected worldwide.
Among the symptoms in the confirmed cases are fever, coughing and breathing difficulties.
Of
the six laboratory-confirmed cases reported to WHO, four cases,
including the two deaths, are from Saudi Arabia and two cases are from
Qatar.
Britain’s
Health Protection Agency, which helped to identify the new virus in
September, said the newly reported case from Qatar was initially treated
in October in Qatar but then transferred to Germany, and has now been
discharged.
Coronaviruses
are typically spread like other respiratory infections, such as flu,
travelling in airborne droplets when an infected person coughs or
sneezes.
The
WHO said investigations were being conducted into the likely source of
the infection, the method of exposure, and the possibility of
human-to-human transmission of the virus.
“Close contacts of the recently confirmed cases are being identified and followed-up,” it said.
It
added that so far, only the two most recently confirmed cases in Saudi
Arabia were epidemiologically linked — they were from the same family,
living in the same household.
“Preliminary
investigations indicate that these two cases presented with similar
symptoms of illness. One died and the other recovered,” the WHO’s
statement said.
Two
other members of the same family also suffered similar symptoms of
illness, and one died and the other is recovering. But the WHO said
laboratory test results on the fatality were still pending, and the
person who is recovering had tested negative for the new coronavirus.
The
virus has no formal name, but scientists at the British and Dutch
laboratories where it was identified refer to it as “London1_novel CoV
2012”.
The WHO urged all its member states to continue surveillance for severe acute respiratory infections.
“Until
more information is available, it is prudent to consider that the virus
is likely more widely distributed than just the two countries which
have identified cases,” it said.
