Question

Suppose that a few cases of coronavirus infection were reported in your locality even
though the residents had ensured high precaution. Now analyze, with examples, (i) the
necessary condition, (ii) the sufficient condition, and (iii) the critical condition that could
have determined the cases of infection.

Answer 1

It is not something uncommon at present that many individuals are getting tested with Covid-19 in spite of the fact that they maintained proper precautions. It's getting really tough to realise and control some subtle and little exposures which may make one contaminated inspite of proper precautions.

a) The necessary conditions for determining covid-19 infection will be those symptoms which must be present for suspecting a covid-19 contamination or infection. For example, presence of fever, feeling of fatigue and cough can be referenced to as the necessary conditions. When a person is having these conditions it is not necessary that he will have covid-19 but when someone is having covid-19 it is pretty necessary that these conditions will be present.

Other than that, in context of necessary conditions for contamination, it can be said that getting outside home, being close to other people and going to places where there are some people like in markets and all can be necessary conditions for the determination of cases of infection.

b) The sufficient conditions are those whose presence can reasonably imply and infer that covid-19 infection is present in an individual. For example, when a person has been tested and the result says positive then this result is sufficient to imply and determine the presence of infection taking into consideration the accuracy of the testing.

Other than that, being in close contact with someone contaminated with Covid-19, and being exposed to their body parts, droplets such saliva or cough droplets or touching them can be sufficient conditions for the determination of cases of infection.

c) The critical conditions determining the presence of covid-19 infection are those which indicates severity of the infection and might be analysed with regard to the knowledge that the tests were positive. For example, these conditions can be breathing problems, loss of olfactory sensation and the blueness of nails which critically indicate the presence of an infection. These symptoms when found with a positive test of covid-19 critically determines the case of covid-19 infection.

Other than that being in places like hospitals where there multiple cases of infection and being in close contact with them can critically determine cares of infection.

It must be said at the end that as new researches are being done everyday on covid-19 and the conditions, the above stated conditions are vulnerable to modification in the near future.
