Saudi Arabia confirms another MERS-CoV case
Today Saudi Arabia's Ministry of Health (MOH) confirmed another MERS-CoV case, the sixth in just over a week and the second in as many days.
The case involves a 27-year-old Saudi man who is hospitalized in a ward in Taif in Mecca province, the MOH said. He is not a healthcare worker and had pre-existing disease and no contact with animals, the agency said. He is symptomatic. No other details were provided.
The MOH has confirmed six cases of MERS-CoV (Middle East respiratory syndrome coronavirus) since Sep 8. The other five patients were hospitalized in intensive care.
The new case brings Saudi Arabia's MERS total to 732 cases, including 302 fatalities.

Study estimates 23,000 listeriosis cases globally, 5,500 deaths
Listeriosis resulted in more than 23,000 illnesses, nearly 5,500 deaths, and almost 173,000 disability-adjusted life-years (DALYs) worldwide in 2010, according to the first estimates of the disease's global burden, published yesterday in Lancet Infectious Diseases with funding from the World Health Organization (WHO).
The authors, from Belgium and the Netherlands, reviewed nearly 12,000 studies on Listeria monocytogenes infections published from Jan 1, 1990, to May 21, 2012; they included 87 in their meta-analysis. They also reviewed national surveillance data when available for WHO member-states without incidence data.
On the basis of their analysis and the world population at the time, they estimated that listeriosis caused 23,150 illnesses (credible interval [CrI], 6,061 to 91,247), 5,463 deaths (CrI, 1,401 to 21,497), and 172,823 DALYs (CrI, 44,079 to 676,465) globally in 2010. The highest incidence rate was in the subregion covering the Caribbean, Central America, and some of South America.
Perinatal cases accounted for 20.7% of the cases (95% CrI, 17.4% to 23.9%). For these cases the overall case-fatality rate (stillbirths and neonatal deaths) was 14.9%. For nonperinatal infections it was 25.9%.
Although listeriosis causes fewer infections and deaths than do several other foodborne pathogens, the fact that it is entirely foodborne, can grow in food with low moisture and high salt content, and can grow at refrigeration temperatures poses significant problems for control.
The authors acknowledge that their estimations are based on data from just over half of the world's population in that they were unable to identify incidence data for much of Africa and the Middle East as well as some Asian countries, and so had to rely on other data sources and assumptions for these gaps.
They encourage further study but state that this first attempt at quantifying the global burden of listeriosis "will enable listeriosis to be included in international prioritisation exercises."

Pakistan reports 13 more polio cases, raising year's total to 158
Pakistan's National Institute of Health in Islamabad today reported 13 new polio cases, raising the country's 2014 count to 158, according to media reports.
A health official said seven of the new cases were reported in the tribal regions and three in Khyber-Pakhtunkhwa province, according to a report in Punch, a Nigerian news service. Three other provinces had one case each.
The count of 158 cases this year is well ahead of the 2013 total of 93 and the 58 cases in 2012, the story said.
This year's cases include 113 reported in the tribal regions, 27 in Khyber-Pakhtunkhwa province, 12 in Sindh, 2 in Punjab, and 3 in Balochistan, according to the story.
A report in The News International, a Pakistani news service, said that all 13 of the latest case-patients are children less than 3 years old.
Pakistan is one of three nations in which polio remains endemic, along with Afghanistan and Nigeria. Vaccination efforts in some parts of the country have been crippled by assassinations and bans imposed by militants who regard the vaccination campaigns as a cover for Western spying or sabotage.

Syrian rebels say tainted measles vaccine killed 34 children
Authorities in a rebel-held area of Syria say at least 34 children died after receiving contaminated measles vaccine doses, and they allege that the contamination might have been caused by saboteurs tied to the Syrian government, according to a report yesterday in The Guardian, a British newspaper.
Today the United Nations Children's Fund (UNICEF) and the WHO announced they would help investigate the deaths of "at least 15 young children" in areas of Syria where measles vaccinations were under way.
The Guardian said the vaccination drive has been suspended and blood samples have been sent to Turkey for analysis. It also said many children in Idlib province, in northwestern Syria, were still in intensive care on Sep 15.
"For as long as the facts remain unclear, the suspension of the immunization campaign in both Idlib and Deir Ezzour provinces is a wise step," the UN and WHO said in a joint statement.
Parents accused the rebel health authorities of supplying out-of-date vaccine and failing to store the vaccine properly, the newspaper said. But rebel officials denied this, saying the vaccines came from the UN and the WHO via the Turkish government, and that the same batch recently was used successfully to vaccinate 60,000 schoolchildren in 30 locations.
The rebel health ministry blamed the contamination on sabotage. "Primary investigations point to a limited security breach by vandals likely connected to the regime, which has been attempting to target the medical sector in Free Syria in order to spread chaos," the ministry said in a statement, according to The Guardian.
Idlib province is held by moderate rebel groups opposed to both Syria's dictator, Bashar al-Assad, and the extremist Islamic State in Iraq and Syria (ISIS), the story noted.
