You are talking about the tuberculosis, probably. Same is true as on today also.
Screening in medical terms means trying to detect a disease for which the patient is not showing signs or symptoms.
Contamination implies the presence of microorganisms that do not necessarily colonize or reproduce in the host. Infection implies colonization and reproduction of the organisms within the host. Disease only occurs when the infection impairs the health of the host. Ifone gets HIV containing blood onthe skin, they have contamination. If HIV gets into their bloodstream and reproduces, they have infection. They don't have disease until they begin showing signs and symptoms of AIDS. Contamination may but does not alwayslead toinfection, and infection may butdoes not always cause disease.

Yes they are.
Overt infections are those which are apparent infections. Overt is defined as open and observable as opposed to covert which is hidden, concealed, or secret. This can be contrasted to the situation in which a person is in the prodromal stage of infection, where the patient is highly infectious but is not showing symptoms yet, or of healthy carriers who carry infectious microbes but appear completely healthy. In short, an overt infection means that you/they know you're infected.
No, he was not born with the disease. He began showing symptoms of the disease ( amyotrophic lateral sclerosis) when he was in his early twenties.
Kapose's Sarcoma (KS) is an opportunistic disease that occurs in people with weakened immune systems. HIV (Human Immunodeficiency Virus) weakens the immune system severely enough for patients to develop KS. HIV is not the only cause of weakened immune systems. Other conditions, such as Lupus, may also cause an individual to develop an opportunistic infection.
A normal blood test will not detect the infection. To diagnose chlamydia, you need a urine test or swab of the vagina, urethra, rectum, throat, or eye. Blood tests can look for evidence of past infection with chlamydia, but these are of no use in determining current infection and aren't used to diagnose or treat disease. A positive blood test showing evidence of past infection will not change as a result of antibiotic treatment.
The answer is yes. It takes 3-14 after infection with the barcteria to start showing clinical signs of the infection
Since most diseases have an incubation period, there are 2 possible answers here. the infection happens on contact but the symptoms will not show until the disease has incubated. It is also highly possible to be infested with a disease, including HIV & Chlamydia, high blood pressure, heart disease, cancer, typhoid and many more & not show any symptoms. That leads to the term that someone is a "Carrier" of a disease. Carriers, were often infected with a disease & went on with life unknowing, but able to spread it to others.
It is loading, be patient
DefinitionSymptomatic can mean showing symptoms, or it may concern a specific symptom. Symptoms are signs of disease or injury and are usually noticed by the patient.Many conditions and diseases have symptoms. A cough can be a symptom of an upper respiratory infection.When someone has the common symptoms associated with a disease or condition, they are considered symptomatic. When a disease exists without noticeable symptoms, the patient is asymptomatic.
