Question
propose a new approach to finding cases – what other surveillance system or activity would you recommend and why?
Solution
Given the nature of monkeypox, a disease that is primarily zoonotic and has the potential for human-to-human transmission, a Syndromic Surveillance System could be a beneficial approach. This system is used to identify illness clusters early, before diagnoses are confirmed and reported to public health agencies, and to mobilize rapid responses, which is particularly useful in detecting early signs of potential outbreaks.
Here's a step-by-step summary of this approach:
-
Implement Syndromic Surveillance: This involves monitoring symptom patterns or clusters within a population to detect a potential public health event. For example, a sudden increase in individuals presenting with fever and rash in healthcare facilities could be an early sign of a monkeypox outbreak.
-
Use of Health Information Technology: Syndromic surveillance relies heavily on health information technologies. Electronic health records (EHRs) and telemedicine platforms can be used to track symptom patterns and trends in real-time, allowing for quicker detection and response.
-
Training Healthcare Providers: Healthcare providers should be trained to recognize the symptoms of monkeypox and to report any suspected cases or unusual symptom patterns immediately. This is crucial for the success of syndromic surveillance.
-
Public Engagement: Encourage the public to report symptoms through hotlines or digital platforms. This can help detect cases that may not seek medical attention.
-
Collaboration with Laboratories: Rapid and accurate laboratory testing is crucial to confirm suspected monkeypox cases. Strengthening the collaboration between healthcare providers and laboratories can ensure timely confirmation of cases.
-
Data Analysis: Regular analysis of the data collected should be conducted to identify trends and patterns, which can help predict and prevent outbreaks.
The advantage of this approach is that it allows for early detection of potential monkeypox cases, even before laboratory confirmation, enabling a rapid public health response to prevent further spread. It also utilizes existing healthcare data, making it a cost-effective approach.

criticize Active case finding The team conducted a systematic active casefinding survey based on the above field case definition. The team visited the two main hospitals of the affected area (Nertiti rural hospital and Nyala) and actively assessed the present medical records, admission sheets, laboratory registers and pharmacy logbooks. Additionally, ‘‘shoe-leather epidemiology’’ was used for active case finding at the village and household levels within the residential areas from which the index cases were reported. The investigation team visited the following villages during the field outbreak investigation missions: • Khour Ramla, • Fukodoko, • Rijl Aldalaba, • Toor, • Tibbi, • Jurfambari, • Norma. Based on the above-mentioned case definition, the investigation team generated the initial outbreak line list. Nine additional cases were added as a result of active case finding, bringing the total to 16 cases for the initial line list. Fresh blood samples were collected from the acutely febrile patients during the household visits (the samples were used for serology and blood films for malaria). Descriptive epidemiology The team analyzed the data descriptively, applying the classical epidemiological traits of person, place and time to gain insights on the reported cases. One of the most interesting findings was that the majority (81.2%) of the cases were young adult males, were related and were in close contact with animals (38% pastoral). Another interesting finding was that most of the cases were initially treated with antimalarial medications, including the recommended treatmentlines that are based on a positive immuno chromatographic (ICT) test for Falciparum Malaria. Family history ofthe disease was confirmed because two families had reported the deaths of immediate family members during the investigation period and the illness had manifested identically in both, with fever and bleeding (hematemesis). Bleeding presented in 80% of cases, while jaundice presented in 19% of cases. Further descriptions of the overall outbreak and the other reported cases will be published separately (Figs. 1 and 2). Hypothesis generation Before laboratory confirmation of the collected blood samples, the investigators generated three hypotheses based on the available descriptions for the reported cases and the surrounding environment, in addition to information from previous
