Iceland using DNA sequencing to fight COVID-19

Decode Genetics in Iceland is focusing on COVID-19 by testing and sequencing the virus in the population. They discovered the virus's spread from various countries, notably Great Britain. A large genetic database helps study the genetic components affecting COVID-19 reactions, revealing differences in infection and severity between genders. Despite Iceland's small size, their methods have been effective, and they aim to be better prepared for future waves.

What was one of the surprising findings about the early spread of COVID-19 in Iceland?

• The virus originated from Iceland itself.

• Early cases were traced back to the Alps and Great Britain.

• The virus was primarily spread by animals.

• Most cases came from the United States.

What is one potential factor that Decode Genetics is investigating in relation to COVID-19?

• The role of climate in virus transmission.

• Genetic components affecting individual reactions to the virus.

• The effect of exercise on virus resistance.

• The impact of diet on virus spread.

What percentage of those who tested positive for COVID-19 in Iceland showed no symptoms?

• 60%

• 25%

• 40%

• 10%

According to Kari Stefansson, what is crucial for managing COVID-19 effectively?

• Using available resources wisely and reacting early.

• Having a large population.

• Focusing only on symptomatic individuals.

• Relying solely on international aid.

What does the final section suggest about Iceland's preparedness for a potential second wave of COVID-19?

• Iceland plans to ignore the possibility of a second wave.

• Iceland is not prepared at all.

• Iceland will rely on other countries for help.

• Iceland will be better prepared but acknowledges there is still much to learn.
