Answer:
CV19 could impact PPP by negatively impacting the market value of goods in an economy that is severely impacted by the virus.
Explanation:
When the economic conditions and demand for goods and services slow down, prices will naturally fall as the individuals selling those goods and services try to attract scarce buyers.
In the case of CV19, if one country is severely impacted by either illness or the measures taken to avoid illness, their economy will slow down and prices will fall. Compared to a country who is not impacted and whose market prices do not fall, PPP between these countries will be affected.
