감염되다

The sentence means 'I was infected with the flu virus.' '감염되었어요' (was infected) is the correct fit. '예방했어요' (prevented), '치료했어요' (treated), and '회복했어요' (recovered) do not fit the context of being exposed to a virus.

The sentence means 'If you go to the hospital, there's a risk of being infected with another disease.' '감염될' (to be infected) is the appropriate word to express the risk of catching a disease. '건강해질' (to become healthy), '나을' (to get better), and '안전할' (to be safe) are opposite in meaning or irrelevant.

The sentence means 'He rested for a month because he was severely infected with the flu.' '감염되어' (being infected, as a reason) correctly connects the infection to the resting period. '감염되자' (as soon as he was infected), '감염되면' (if he is infected), and '감염되더라도' (even if he is infected) do not fit the causal relationship.

The sentence means 'A new virus is rapidly infecting worldwide.' While '확산되고' (spreading) also seems plausible, '감염되고' (being infected) specifically refers to people getting the disease, which fits the context of a virus affecting individuals. '예방되고' (being prevented) and '치료되고' (being treated) are the opposite of the context.

The sentence means 'That child had a high fever because they were infected with germs.' '감염되어서' (because of being infected) expresses the reason for the high fever. '감염될수록' (the more they are infected), '감염되기 전에' (before being infected), and '감염되거나' (or being infected) do not make sense in this context.

The sentence means 'Washing hands frequently is important to prevent being infected with diseases.' '감염되는' (being infected) is the correct choice to complete the phrase 'prevent being infected'. '예방하는' (preventing), '치료하는' (treating), and '회복하는' (recovering) are incorrect here as the action is 'preventing getting infected'.
