Absolutely - they are known as 'carriers'. They exhibit no outward signs, yet they are able to carry and pass on a disease to other people.
Yes you can be infected with a pathogen but not show any signs or symptoms but you can still pass it on it other people.
Sure. Many people can be carriers of disease but not actually having symptoms themselves.
Lupus is a serious autoimmune disease, but it is not contagious. You cannot *pass on* the lupus rash to someone else.
Yes, they do in fact have to have mono in order to pass it on to others. That does not mean however, that they have to have symptoms of mono. A person can be a carrier, meaning that they have no signs or symptoms of a disease but are carrying it and can transmit it to others.
Yes, but no. He has a special hereditary effect that allows him to carry the disease, without showing full symptoms. He can still control himself and act 'normal', while still being able to pass the virus.
in sickle cell trait you don't actually have the disease. you are only able to pass the disease to your kids if you marry a person with sickle cell or that also has the trait. sickle cell disease is when you actually have the disease. you can pass it to your kids if you marry someone with the trait or the disease. if you marry someone without a trait or disease then your kids will most likely have the trait.
It is very possible. The onset of symptoms is usually later in life, after a person will have had children.
CF carriers do not show CF symptoms themselves, but can pass the problem CF gene to their children
No you can not be a carrier of HPV without having it yourself. A "carrier" is a common language term for someone who has infection and can infect others, but who has no symptoms of the infection. You can't pass an infectious disease like HPV unless you yourself are infected.
Asymptomatic-- Persons who carry a disease and are usually capable of transmitting the disease but who do not exhibit symptoms of the disease are said to be asymptomatic.
they have one normal hemoglobin gene that can produce functional hemoglobin to carry oxygen effectively, compensating for the abnormal hemoglobin produced by the gene for sickle cell disease. This keeps their red blood cells from sickling and causing blockages in blood vessels that lead to symptoms of the disease.
No, but if your pregnant and you get fifth disease you could pass on the sickness to the fetus and increase risk of still-birth and miscarriage.
