Q & A

What is the main security threat discussed in the speech?

The main security threat discussed is infectious diseases, which pose a significant risk to global health and security.

How many people died from infectious diseases in 2019?

In 2019, 13.7 million people worldwide died from infectious diseases, with three million of these being children under the age of five.

What regions were most affected by infectious diseases?

Sub-Saharan Africa was particularly affected, with a death rate of 52.6 per 100,000 people for bloodstream infections, compared to 37.7 in high-income countries.

What was the significance of COVID-19 in the context of the speech?

COVID-19 highlighted that infectious diseases are not confined to specific countries and that they reveal the vulnerabilities in global healthcare systems, affecting society as a whole.

What example does the speaker give to illustrate testing disparities in Sudan?

The speaker notes that Sudan had seven COVID-19 testing centers for a population of 46 million, while their home region, with a much smaller population of 630,000, also had seven centers, illustrating the lack of testing capacity in Sudan.

What personal experiences did the speaker share regarding health challenges in Sudan?

The speaker shared experiences of witnessing children die from malaria, a disease that is largely controlled in many countries, which motivated their desire to find health solutions.

What is the primary goal of the speaker's research?

The primary goal is to create a rapid, reliable, and affordable biosensor that can detect diseases in their early stages.

How does the biosensor function according to the speaker?

The biosensor acts like a detective that finds tiny clues in our bodies and sends out signals indicating the presence of diseases, which can be read through accessible devices like smartphones.

What technology did the speaker develop in their lab?

The speaker developed a highly sensitive COVID-19 biosensor that can detect the virus before symptoms appear, surpassing existing sensor technologies.

What call to action does the speaker make towards the end of the speech?

The speaker encourages women in STEM and underrepresented individuals to join the field of discovery and work together to create a world where healthcare is accessible for everyone.
