ANATOMY

Detailed explanation-1: -Infectious diseases can be viral, bacterial, parasitic or fungal infections. There’s also a rare group of infectious diseases known as transmissible spongiform encephalopathies (TSEs).

Detailed explanation-2: -A common example of a localised infection is an infected wound. This type of localised infection does not generally make a person feel unwell, but without appropriate treatment, it could cause more serious problems, eventually leading to a systemic infection.

Detailed explanation-3: -Localized Infection Swollen lymph nodes may also be apparent. Infections involving the mucous membranes in the eyes, nose, and respiratory tract will cause increased mucus production from the affected sites. Dissemination to other locations in the body may occur 1-4 weeks after infection.

Detailed explanation-4: -While a primary infection can practically be viewed as the root cause of an individual’s current health problem, a secondary infection is a sequela or complication of that root cause. For example, an infection due to a burn or penetrating trauma (the root cause) is a secondary infection.
