People take painkillers to treat the symptoms of illness.
Painkillers cannot destroy pathogens as they treat the symptoms.
Examples of painkillers include paracetamol and calpol.
Antibiotics destroy bacteria by damaging the bacterial cell wall.
Different bacterial diseases require different antibiotics as they are different diseases.
Antibiotics are being overused and bacteria are becoming resistant to them.
Mutation occurred in the bacteria giving some bacteria resistant to the antibiotic.
Those bacteria without mutation are destroyed by the antibiotic.
The resistantbacteria are not killed by the antibiotic.
These resistantbacteriareproducequickly, passing on their resistance.
The population of resistant bacteria increases.
We can control the spread of infectious diseases by washing hands, social distancing, vaccinations, gloves, masks and aprons, hand sanitizer, isolation, and cleaning surfaces.
The overuse of antibiotic methicillin led to the increase of mutation occurred in bacteria as bacteria reproduce quickly, passing on their resistance which means if more people take methicillin the resistant bacteria will not be destroyed by the antibiotic and it will make the bacteria become moreresistant.
