Answer to Question #131671 in Physical Chemistry for Zain Abbas

Question

An infected person who takes no precautions has a 60% chance of infecting one other person per day. If an infected person wears a mask, then that person has a 5% chance of infecting one other person per day. If an infected person practices social distancing, then that person has a 20% chance of infecting one other person per day. If a person does both, then that person has a 1% chance of infecting one other person per day In this city, 30% of the population wear masks and 40% of the population practices social distancing. It is also found that mask-wearing and social distancing behaviours are not correlated. At the start of day 1, there are 100 infected people in the city. Using the information given, and assuming that infected people do not stop being infectious, estimate the number of infected people after 10 days.

Answer 1

Yes, some coronaviruses can be transmitted from person to person, usually after close contact with an infected patient, for example, in a household workplace, or health care centre.

Based on what we currently know, transmission of COVID-19 is primarily occurring from people when they have symptoms, and can also occur just before they develop symptoms, when they are in close proximity to others for prolonged periods of time.

While someone who never develops symptoms can also pass the virus to others, it is still not clear to what extent this occurs and more research is needed in this area.

after 10 days infected people approx 32 times that is approx 3200 people infected approx
