Ebola respons-ibility: moving from shared to multiple responsibilities

Combating threats of infectious diseases has been increasingly framed as a global shared responsibility for a multi-actor framework, of states, international organisations and non-governmental actors. However, the outbreak of Ebola Virus Disease (EVD) has shown that this governance framework has not been able to limit the spread of this virus, despite the normative and legislative changes to global disease control. By unbundling the concept of responsibility, this article will assess how global shared responsibility may have failed due to the fact that accountability does not fall on any one state or stakeholder, highlighting an inherent weakness with the global disease governance regime. As such, this paper concludes that a move towards multiple responsibilities may prove a more effective mechanism for ensuring global health security

Global Mortality Estimates for the 2009 Influenza Pandemic from the GLaMOR Project: A Modeling Study

Background: Assessing the mortality impact of the 2009 influenza A H1N1 virus (H1N1pdm09) is essential for optimizing public health responses to future pandemics. The World Health Organization reported 18,631 laboratory-confirmed pandemic deaths, but the total pandemic mortality burden was substantially higher. We estimated the 2009 pandemic mortality burden through statistical modeling of mortality data from multiple countries. Methods and Findings: We obtained weekly virology and underlying cause-of-death mortality time series for 2005–2009 for 20 countries covering ~35% of the world population. We applied a multivariate linear regression model to estimate pandemic respiratory mortality in each collaborating country. We then used these results plus ten country indicators in a multiple imputation model to project the mortality burden in all world countries. Between 123,000 and 203,000 pandemic respiratory deaths were estimated globally for the last 9 mo of 2009. The majority (62%–85%) were attributed to persons under 65 y of age. We observed a striking regional heterogeneity, with almost 20-fold higher mortality in some countries in the Americas than in Europe. The model attributed 148,000–249,000 respiratory deaths to influenza in an average pre-pandemic season, with only 19% in person

Echoviruses diagnosed in two Children presenting with Acute Flaccid Paralysis (AFP): An Illustration of the Evolving role of the Zambian AFP Surveillance Programme in the Absence of Polio

Background: The Enteric Cytopathic Human Orphan virus commonly referred to by  the acronym ECHO virus has been known to cause acute flaccid paralysis (AFP). Zambia has since 1993 run a national AFP surveillance program to primarily detect and confirm poliomyelitis cases. Through this program other enteroviruses have  been confirmed to be associated to the non-polio cases. We describe two patients with acute flaccid paralysis presenting like poliomyelitis and yet are non-polio cases associated with ECHO virus.Case reports: In March 1995, a 2 year old male from Misisi compound, presented at the UTH with muscle weakness and paralysis of sudden onset. Aside from the acute flaccid paralysis presenting in both legs and arms, the child had no other signs of  symptoms of significance. Laboratory investigations using the WHO polio laboratory network standard protocols revealed the  presence of ECHO 7 virus. In April 1995, a 4 year old girl from Kamwala South in Lusaka presented at the UTH with symptoms and signs of AFP of asymmetrical presentation affecting the Left upper and lower limbs, fever and sore throat. Two stool  specimens collected for laboratory analysis revealed the presence of Echovirus untyped.Discussion: AFP is a neurological condition primarily suspected as a poliomyelitis commonly seen in children below 15 years defined by sudden onset of weakness and floppiness affecting usually one or more limbs. Laboratory analysis has revealedother viruses including the Echovirus being associated with acute flaccid paralysis. This case series reveals Echovirus 7 and Echovirus untyped as being associated with AFP cases that presented to the UTH initially suspected to be poliomyelitis.Conclusion: The clinical manifestations and laboratory results provide evidence of ECHO virus causing acute flaccid paralysis similar to that caused by polio virus. The last wild polio cases circulating in Zambia were in 2001. It is important that Zambia continues to investigate other causes of AFP for clinical decision making, scientific documentation and policy guidance

Identification of Pneumocystis carinii DNA by polymerase chain reaction in necropsy lung samples from children dying of respiratory tract illnesses.

Polymerase chain reaction for Pneumocystis carinii DNA was performed on necropsy lung samples from children by means of P carinii -specific primers.P carinii DNA was identified in 22 of 22 (100%) samples with histologically proven P carinii pneumonia and 13 of 75 (17%) with non-P carinii pneumonia respiratory illness (sensitivity, 100%; specificity, 83%). The low specificity precludes the use of polymerase chain reaction as an alternative to histopathologic diagnosis

Identification of Pneumocystis carinii DNA in oropharyngeal mouth washes from AIDS children dying of respiratory illnesses.

Polymerase chain reaction (PCR) using Pneumocystis carinii-specific primers pAZ 102-H(5'-GTGTACGTTGCAAAGTACTC-3') and pAZ 102-E(5'-GATGGCTGTTTCCAAGCCCA-3') was performed on oropharyngeal washes obtained at autopsy from 22 AIDS children with histologically confirmed P. carinii pneumonia (PCP), and 48 control AIDS children who died from other infections. Fifteen of 22 (68%) PCP samples and none of 48 (0%) control samples had detectable P. carinii DNA (sensitivity 68%; specificity 100%; positive predictive value 100%; negative predictive value 87%). This method requires further validation in clinical practice
