What is the subclinical phase of disease?
This stage of subclinical disease, extending from the time of exposure to onset of disease symptoms, is usually called the incubation period for infectious diseases , and the latency period for chronic diseases. During this stage, disease is said to be asymptomatic (no symptoms) or inapparent.
Why are subclinical diseases significant?
The identification of subclinical disease may therefore provide a very important marker of the effects of risk factors , such as lipoprotein levels, blood pressure, cigarette smoking, and diabetes, on the cardiovascular system among relatively asymptomatic individuals.

1- Some people have a stronger “innate” immune response to the virus . 2- Some people encounter a smaller viral load. Personally, I have an additional one: 3- People with stronger “adaptive” immune system are able to respond to an infectious contact much quicker and therefore with fewer symptoms!
What is a latent disease?
A latent infection is an infection that is hidden, inactive, or dormant . As opposed to active infections, where a virus or bacterium is actively replicating and potentially causing symptoms, latent infections are essentially static.

Two examples of a secondary infection are: A vaginal yeast infection after taking antibiotics to treat an infection caused by bacteria.
Which of the following may lead to disease susceptibility?
Susceptibility and response to an agent are influenced by factors such as genetic composition , nutritional and immunologic status, anatomic structure, presence of disease or medications, and psychological makeup.
What happens when a virus becomes latent?
When a virus is present in the body but exists in a resting (latent) state without producing more virus. A latent viral infection usually does not cause any noticeable symptoms and can last a long period of time before becoming active and causing symptoms.
