What are infectious diseases?
Infectious diseases are a type of illness that is caused by microorganisms such as bacteria, viruses, fungi, or parasites that can invade the body & cause harm.
These microorganisms can spread from one person to another or from animals to humans, either directly or indirectly through contaminated food, water, or surfaces.
Infectious diseases are a major public health concern worldwide & can have significant social, economic, & health impacts.
Some of the most common infectious diseases include the flu, pneumonia, tuberculosis, HIV/AIDS, hepatitis, & malaria, but there are many others as well.
One of the challenges of infectious diseases is that they can mutate & become resistant to treatments, making them more difficult to manage & control.
For example, bacteria that are resistant to antibiotics are becoming more common, & there is concern that diseases such as tuberculosis & pneumonia could become more difficult to treat.
Preventing the spread of infectious diseases is an important part of public health, & can be achieved through a variety of measures.
Some of these measures include vaccination, hand washing, practicing safe s*x sick people, & using protective equipment such as gloves, masks, & gowns when caring for infected individuals.
