WHO: MERS-CoV situation update, March 2018

WHO

MERS situation update March

At the end of March 2018, a total of 2189 laboratory-confirmed cases of Middle East respiratory syndrome (MERS), including 782 associated deaths (case–fatality rate: 35.7%) were reported globally; the majority of these cases were reported from Saudi Arabia (1814 cases, including 708 related deaths with a case–fatality rate of 39%).

In March, 7 laboratory-confirmed cases of MERS were reported in Saudi Arabia including 1 associated death. A cluster-case from a hospital in Riyadh region was reported, with 6 laboratory-confirmed cases including 3 associated deaths. The date of onset of the first case was 23 February 2018. The date of onset of the last laboratory-confirmed case from the hospital cluster was 3 March 2018; since then, there have been no new cases reported from this cluster. Further investigation on the nature of transmission is ongoing.

The demographic and epidemiological characteristics of the cases reported in March 2018 do not show any significant difference compared to cases reported during the same period from 2012 to 2017. Owing to improved infection prevention and control practices in hospitals, the number of hospital-acquired cases of MERS has dropped significantly since 2015.

The age group 50–59 years continues to be at the highest risk for acquiring infection as primary cases. The age group 30–39 years are most at risk for secondary cases. The number of deaths is higher in the age group 50–59 years for primary cases and 70–79 years for secondary cases.”

Household Transmission of Ebola Virus: risks and preventive factors, Freetown, Sierra Leone, 2015

J Infect Dis

“…..We enrolled 150 index Ebola cases and 838 contacts; 83 (9.9%) contacts developed Ebola during 21-day follow-up. In multivariable analysis, risk factors for transmission included index case death in the household, Ebola symptoms but no reported fever, age <20 years, more days with wet symptoms; and providing care to the index case (P<0.01 for each). Protective factors included avoiding the index case after illness onset and a piped household drinking water source (P<0.01 for each).….”

CDC: During week 13 (March 25-31, 2018), influenza activity decreased in the United States.

CDC

Synopsis:

 

  • Viral Surveillance: Overall, influenza A(H3) viruses have predominated this season. Since early March, influenza B viruses have been more frequently reported than influenza A viruses. The percentage of respiratory specimens testing positive for influenza in clinical laboratories remains elevated.
  • Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was below the system-specific epidemic threshold in the National Center for Health Statistics (NCHS) Mortality Surveillance System.
  • Influenza-associated Pediatric Deaths: Five influenza-associated pediatric deaths were reported.
  • Influenza-associated Hospitalizations: A cumulative rate of 99.9 laboratory-confirmed influenza-associated hospitalizations per 100,000 population was reported.
  • Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 2.4%, which is above the national baseline of 2.2%. Seven of 10 regions reported ILI at or above region-specific baseline levels. Two states experienced high ILI activity; eight states experienced moderate ILI activity; New York City and 12 states experienced low ILI activity; and the District of Columbia, Puerto Rico, and 28 states experienced minimal ILI activity.
  • Geographic Spread of Influenza: The geographic spread of influenza in 11 states was reported as widespread; Guam, Puerto Rico and 26 states reported regional activity; the District of Columbia and 10 states reported local activity; and the U.S. Virgin Islands and three states reported sporadic activity.

On Saturday, April 7th, at 7:45 PM local time, amidst continuous bombardment of residential neighborhoods in the city of Douma, more than 500 cases -the majority of whom are women and children- were brought to local medical centers with symptoms indicative of exposure to a chemical agent.

“Following a brief ceasefire that only lasted for a couple of days, the city of Douma, East Ghouta, was again subjected to heavy shelling that resulted in dozens of casualties and hundreds of injuries. The attacks included the systematic targeting of medical centers and civil defense teams, resulting in the  the destruction of the majority of the civil defense centers and a large number of ambulances and rescue vehicles, heavily paralyzing the medical capacity of the city

On Saturday, April 7th, at 7:45 PM local time, amidst continuous bombardment of residential neighborhoods in the city of Douma, more than 500 cases -the majority of whom are women and children- were brought to local medical centers with symptoms indicative of exposure to a chemical agent. Patients have shown signs of respiratory distress, central cyanosis, excessive oral foaming, corneal burns, and the emission of chlorine-like odor.

During clinical examination, medical staff observed bradycardia, wheezing and coarse bronchial sounds. One of the injured was declared dead on arrival. Other patients were treated with humidified oxygen and bronchodilators, after which their condition improved. In several cases involving more severe exposure to the chemical agents, medical staff put patients on a ventilator, including four children. Six casualties were reported at the center, one of whom was a woman who had convulsions and pinpoint pupils. 

Civil Defense volunteers have reported more than 42 casualties found dead in their homes, with similar clinical symptoms of cyanosis and corneal burns. Civil defense volunteers were unable to evacuate the bodies due to the intensity of the odor and the lack of protective equipment. The reported symptoms indicate that the victims suffocated from the exposure to toxic chemicals, most likely an organophosphate element.

Following the chemical attack, the target site and the surrounding area of the hospital receiving the injured were attacked with an explosive barrel, which hindered the ability of the ambulances to reach the victims.

The Syrian American Medical Society (SAMS) and the Syrian Civil Defense (White Helmets) have documented nearly 200 uses of chemical weapons in Syria since 2012. Previous United Nations Security Council Resolutions on this matter have failed in stopping the use of chemical weapons in Syria.……”
