My younger brother is a sick child, always under the care of a doctor.

Taking care of a sick child is tough.

He needs special care because of his inherited disease.

He got infected with brucellosis because he was handling cows that were infected with the disease.

He used malingering to skip school.

Ebola virus disease is highly infectious and can cause severe symptoms.

I have a severe headache due to meteoropathy.

I caught a cold, so I decided to take a sick leave.

He says 'sickness and health start with the mind,' and strives to have positive thoughts every day.

He received a rabies vaccination.
