Asymptomatic carriers can be categorized by their current disease state. [5] When an individual transmits pathogens immediately following infection but prior to developing symptoms, they are known as an incubatory carrier. Humans are also capable of spreading disease following a period of illness.
An obligate carrier is an individual who may be clinically unaffected but who must carry a gene mutation based on analysis of the family history; usually applies to disorders inherited in an autosomal recessive and X-linked recessive manner.
The Casablanca-class escort carrier was a series of escort carriers constructed for the United States Navy during World War II. They are the most numerous class of aircraft carriers ever built. Fifty were laid down, launched and commissioned within the space of less than two years – 3 November 1942 through to 8 July 1944.
A supervirus which affects everyone on Earth over the age of puberty. It spreads quickly and is almost 100% fatal, although there are apparently some carriers who do not develop the disease. After the disease has run its course it disappears, allowing those then reaching puberty to survive, although there is a constant threat of it returning.
Disease carrier could refer to: Asymptomatic carrier , a person or organism infected with an infectious disease agent, but displays no symptoms Genetic carrier , a person or organism that has inherited a genetic trait or mutation, but displays no symptoms
EBV also establishes a lifelong dormant infection in some cells of the body's immune system. A late event in a very few carriers of this virus is the emergence of Burkitt's lymphoma and nasopharyngeal carcinoma, two rare cancers. EBV appears to play an important role in these malignancies, but is probably not the sole cause of disease.
Carrier females have a 50% chance of passing the DMD mutation in each pregnancy. Sons who inherit the mutation will be affected; daughters who inherit the mutation will be carriers. Men who have Becker muscular dystrophy can have children, and all their daughters are carriers, but none of the sons will inherit their father's mutation. [12] [14 ...
A person born with one normal copy and one defective copy is called a carrier. They will produce less α-L-iduronidase than an individual with two normal copies of the gene. The reduced production of the enzyme in carriers, however, remains sufficient for normal function; the person should not show any symptoms of the disease. [citation needed]
