What is the common examiner trap about Science & Tech in UPSC exams?

They will try to trick you by: 1) Confusing the Ebola virus genus (Orthoebolavirus) with the family (Filoviridae). 2) Swapping the declared status (PHEIC) with a 'Pandemic Emergency' (which the WHO explicitly said this outbreak does NOT meet). 3) Mixing up the names of approved vaccines (Ervebo, Zabdeno/Mvabea) with the specific variant (Bundibugyo) which has no approved vaccine.

What should UPSC aspirants remember about Science & Tech for Prelims?

1. Target this Data: ~50% average case fatality rate of Ebola virus disease. 2. Target this Nodal Body: World Health Organization (WHO) declares PHEIC. 3. Target this Legal Point: PHEIC is declared under the International Health Regulations (IHR 2005).

Detailed Analysis & Strategic Depth

Context / Background

Ebola Virus Disease (EVD) is a severe zoonotic hemorrhagic fever caused by viruses in the genus Orthoebolavirus. The Democratic Republic of Congo (DRC) has experienced over 20 Ebola outbreaks historically, making it an endemic region. The World Health Organization (WHO) has a framework under the International Health Regulations (IHR) to declare a Public Health Emergency of International Concern (PHEIC) for events that pose a risk to other countries and require a coordinated response.

Core Analysis & Implications

The declaration of a PHEIC for this outbreak, caused by the Bundibugyo variant, is significant due to three key factors: the high case fatality rate (~50%), the absence of approved vaccines/therapeutics for this specific variant, and the cross-border spread into Uganda. The WHO's statement highlights 'significant uncertainties' about the true scale and geographic spread, pointing to a potentially larger undetected outbreak. This move mandates international cooperation for surveillance, containment, and resource mobilization, but crucially, WHO advises against border closures, balancing public health with economic disruption.

Future Outlook / Way Forward

The immediate focus will be on outbreak containment measures: safe burial practices, contact tracing, patient isolation, and supportive care. International health agencies will need to scale up diagnostic capacity (using RT-PCR, ELISA tests) and potentially fast-track research on monoclonal antibodies (mAb114, REGN-EB3) for the Bundibugyo strain. The situation tests the global health architecture post-COVID-19, emphasizing the need for robust surveillance systems in vulnerable regions to prevent local outbreaks from becoming global crises.
