People's personal views about infectious diseases can have a detrimental effect on the health and safety of people. Negative perceptions of illnesses, such as fear or stigma, can lead to delays in seeking medical care, under-utilization of preventive measures, or the rejection of medical advice. This can lead to more serious conditions and even spread of the disease to other people. It is important for people to have accurate knowledge and access to services, so that they can make informed decisions and take appropriate actions to protect their own health, as well as the health of others.
