1. How can surveillance help to detect and control the disease?
Surveillance can help detect and control dengue by detecting outbreaks in order to initiate timely and effective control measures, monitoring trends of incidence and number of severe cases and deaths, assessing and confirming possibility of outbreaks, and monitoring the impact of control interventions.
2. Should we conduct active or passive surveillance or both for the disease, why?
Both active and passive surveillance should be conducted for dengue because we need data from both health facilities reports and from active surveillance since many dengue cases are asymptomatic or mild and self-managed, leading to underreporting of actual number of dengue cases.
3. Which method should be best to identify cases, why?
1. Cases in medical facilities VS community
To identify cases of severe dengue, using cases in medical facilities is better because most severe cases were treated in medical facilities. For mild and asymptomatic cases, community is better because these cases are usually not underreported.
2. Sentinel VS population-based surveillance
Sentinel surveillance is best to identify cases of dengue because it provides higher quality and more detailed data.
3. Case-based VS aggregated surveillance
For faster identification of potential outbreaks, aggregated surveillance is better because it collects and analyzes data on group of cases for a specific region and time period. If the goal is to understand disease characteristics, case-based is better because it collects information about each case at the individual level.
4. Syndromic VS laboratory-confirmed surveillance
Syndromic surveillance is better for early detection of outbreaks dengue cases and related health events, allowing for rapid response.
4. What dissemination tools will you choose to disseminate monkeypox surveillance information? Why do you choose this/these tools?
I will choose ongoing, real-time dissemination tools such as ProMED because it is free, easily available on the internet, and have a large audience.
