Which of the following can support pathogen 'attenuation'?

Question

Quizplus · Accepted Answer

Pathogen attenuation refers to the reduction in virulence or the ability of a pathogen to cause disease. Vaccination can lead to attenuation by introducing a weakened form of the pathogen to the immune system, prompting an immune response without causing the disease. Sanitation and new hygiene habits, such as mask-wearing, can reduce the spread of pathogens, potentially leading to a decrease in virulence over time as the pathogen adapts to a lower transmission rate. Genetic adaptation in the host can also lead to attenuation, as populations become more resistant to the pathogen, reducing its impact. Therefore, all the options listed can support pathogen attenuation in different ways.
