Viruses that can be passed from person to person are infectious diseases.
Yes. Infectious diseases are highly infectious and are easily passed from person to person.
While a person's genes may make him or her more or less susceptible to a particular infectious disease, infectious disease are not caused by genes. Infectious diseases are caused by microorganisms (bacteria, viruses) that multiply in the body and that can be transferred from one person to another.
Nutritional diseases are not classified as infectious disease because they do not fit the definition of 'infectious'. They cannot be transmitted from one person to another and the causative agents come from the environment.
Infectious diseases are caused by viruses, parasites, bacteria, and fungi. Infectious diseases can spread from person to person or from animal to human.
Infectious diseases that are easily spread from person to person.
There are Infectious Diseases and Non infectious Diseases. Infectious diseases can be transmitted from person to person, and can be spread from one living thing to another are known as communicable diseases. They can be caused by, Bacteria, Viruses, Protists, etc. which is the Plague. Non infectious diseases can not be transmitted from person to person, these are things like Cancers.
Infectious diseases are those diseases which are caused by infectious agents (which include microorganisms such as bacteria, fungi, protozoa and virus, as well as some multicellular animals such as worms) and hence they are the ones which can spread from one person to another. Non-infectious diseases are those diseases that are not caused by infectious agents and do not spread from one person to another.
A person who studies infectious diseases.
Diseases that are not transmitted from one person to another
Cancer, diabetes, hypertension are few non infectious diseases. These diseases are not transferred from one person to other person.
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Some - but not all - infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious. So something can be infectious without being contagious.
Because AIDS weakens the immune system, which makes the person susceptible to other diseases.
It is indeed caused by a micro-organism transferable from an infected person to a susceptible contact. However it is the least infectious of all infectious diseases. Immunity of the human beings against the invading pathogenic organism is very high. In this respect leprosy differs from most infectious diseases.Dr R Ganapati,Bombay leprosy Projecte-mail : firstname.lastname@example.org
Because the HIV virus weakens the immune system of the body.
A doctor who specializes in infectious diseases, which means diseases that you can "catch" from another person or from a thing like a mosquito.
Communicable diseases are those diseases, which can be transferred from one person to another. They include the infectious diseases, which are caused by various infections by microorganisms. They are also communicable.
infectious diseases are caused by organisms which can spread from one person to the other commonly - bacteria, viruses, fungi and parasites.
Infectious diseases spread either by person to person contact, or indirectly by a vector or a fomite.
sexually transmitted diseases (STD)s
Non-infectious cannot be spread from person to person. Infectious can be spread from person to person. This would include Viruses, Fungi, and STD's Infectious diseases are caused by pathogens , which are disease causing organisms. The major groups of pathogens are viruses, bacteria, fungi, protozoans and multi-cellular parasites. Non-infectious diseases are not caused by pathogens but can be caused by physiological malfunction, environmental (or chemical) factors, heredity (e.g. faulty gene/chromosome combinations), unknown causes or a combination of factors.
Damage the immune system
Infectious Disease can be spread from person to person though coughing or sneezing or some other means.(The Common cold, The Flu). Non-Infectious Disease cannot be spread from person to person. (Cancer, Heart Disease).
