Ebola Outbreak Response; Experience and Development of Screening Tools for Viral Haemorrhagic Fever (VHF) in a HIV Center of Excellence Near to VHF Epicentres

Abstract

IntroductionThere have been 3 outbreaks of viral hemorrhagic fever (VHF) in Uganda in the last 2 years. VHF often starts with non-specific symptoms prior to the onset of haemorrhagic signs. HIV clinics in VHF outbreak countries such as Uganda see large numbers of patients with HIV 1/2 infection presenting with non-specific symptoms every day. Whilst there are good screening tools for general health care facilities expecting VHF suspects, we were unable to find tools for use in HIV or other non-acute clinics.MethodsWe designed tools to help with communication to staff, infection control and screening of HIV patients with non-specific symptoms in a large HIV clinic during the outbreaks in Uganda. We describe our experiences in using these tools in 2 Ebola Virus Disease outbreaks in Uganda.ResultsDuring the Ebola Virus Disease (EVD) outbreaks, enhanced infection control and communication procedures were implemented within 24 hours of the WHO/Ministry of Health announcement of the outbreaks. During course of these outbreaks the clinic saw 12,544 patients with HIV 1/2 infection, of whom 3,713 attended without an appointment, suggesting new symptoms. Of these 4 were considered at risk of EVD and seen with full infection procedures; 3 were sent home after further investigation. One patient was referred to the National Referral Hospital VHF unit, but discharged on the same day. One additional VHF suspect was identified outside of a VHF outbreak; he was transferred to the National Referral Hospital and placed in isolation within 2 hours of arriving at the HIV clinic.DiscussionUse of simple screening tools can be helpful in managing large numbers of symptomatic patients attending for routine and non-routine medical care (including HIV care) within a country experiencing a VHF outbreak, and can raise medical staff awareness of VHF outside of the epidemics.

Ebola outbreak preparedness and preventive measures among healthcare providers in Saudi Arabia

“…The highest priority must be given to infection control measures and best practices [8]. Other related studies also support these findings: identification of high risk patients, and use of risk management strategy [26,27]; use of universal blood and body fluid precautions [26]; and safe provision of intensive treatment with specifications like airlock and negative pressured room, and wearing of intensive care unit (ICU) itemized PPE, including wearing of singleuse impermeable gowns, hoods, face masks, goggles, two pairs of gloves and one with extended cuffs, and boots [5,25], will considerably decrease the spread of EVD among healthcare workers.…”

Ebola Virus Outbreak 2014: Clinical Review for Emergency Physicians

“…48 RT-PCR is currently the main method for rapid and accurate diagnosis of Ebola viral disease. 49 A study involving 26 laboratory-confirmed cases reported a sensitivity of RT-PCR of 100% (95% confidence interval 86.3% to 100%) compared with a criterion standard of enzyme-linked immunosorbent assay antigen detection and 91% (95% confidence interval 70.8% to 98.9%) compared with IgM detection. The specificity of RT-PCR was 97% (95% confidence interval 85.1% to 99.9%).…”
