Correct Answer:
B. March 2020
The correct answer is March 2020 because the World Health Organization (WHO) officially declared the global outbreak a pandemic during this month.
- Step 1 (The Declaration): On March 11, 2020, WHO Director-General Dr. Tedros Adhanom Ghebreyesus stated during a media briefing that the spread of COVID-19 had reached the point where it could be characterized as a global pandemic.
- Step 2 (Context): Prior to this, the WHO had labeled the situation a Public Health Emergency of International Concern (PHEIC) in late January 2020 as the virus spread rapidly beyond its initial epicenter.
- Incorrect Options:
- December 2019 is incorrect because this marks when the first clusters of the virus were identified in Wuhan, China, not when it was declared a pandemic.
- December 2020 is incorrect because the global pandemic status had already been active for nine months by this time.
- March 2021 is incorrect because it is exactly one year after the official announcement was documented.
