What is the difference between infectious and non-infectious diseases?

What is the difference between them and what do they mean other than one being infectious and one not being infectious.

An infectious disease is a clinically evident disease of humans or animals that damages or injures the host so as to impair host function, and results from the presence and activity of one or more pathogenic microbial agents, including viruses, bacteria, fungi, protozoa, multicellular parasites, and aberrant proteins known as prions. Transmission of an infectious disease may occur through several pathways; including through contact with infected individuals, by water, food, airborne inhalation, or through vector-borne spread. The rest of the diseases can be classified as noninfectious diseases. Most of them are degenerative diseases such as diabetes, cancer, mental illness, etc.  (+ info)

What is the difference between infectious and non infectious diseases?

What is the difference between infectious and non infectious diseases?

An infectious disease is communicable (contagious), and non-infectious diseases are harder to transfer.  (+ info)

What causes the emergence and reemergence of infectious diseases?

What causes the emergence and reemergence of infectious diseases?

-Thank you sooo much!

Many things cause the emergence/reemergence of infectious diseases: antimicrobial resistance, increasing global travel, globalization of the food supply, ecological and climate changes, people and wild animals living in closer proximity and human behavior to name a few.  (+ info)

How long can impetigo live and be infectious outside of a human host?

I'm not using the same towels and I am disinfecting everything regularly. Still curious... For example, if I use a towel to dry off after showering how long can the towel cause infection? Or if I itch then get it on my hand then touch a doorknob can it live on the doorknob for a while and still be infectious?

Yes, it will infect others if they touch the doorknob. Impetigo remains contagious until the area is disinfected and until your rash has disappeared.

Check out the sources I've provided for more info. :)  (+ info)

What's the difference between contagious and infectious?

I was at a party the other night were a guy posed this question and stated that there is no simple answer. I then asked if there actually is a difference between the two. That too, he responded stating that there is no simple answer. So first of all, is there a difference between contagious and infectious? If so, what is the difference? Thanks.

A contagious disease is transmitted from one living being to another by direct or indirect contact. The agent responsible is called infectious.
An infectious diseaseis caused by a pathogenic organism.
A contagious disease is an infetious one that can be passed on either by direct contact like touching or indirect where the organisms are passed on on an object that can carry them.  (+ info)

What Are Some Good Books About the Infectious Diseases or Viruses?

Hi, I'm rising sophomore who wants to be a virologist when grow up. I really love to read viruses- and infectious diseases-related books such as Hot Zone, Smallpox, Polio, etc.

Do you know any good books about the viruses and infectious diseases?

The Coming Plague: Newly Emerging Diseases in a World Out of Balance by Laurie Garrett-

The Hot Zone by RIchard Preston about the discovery of the ebola virus-

The Great Mortality: An Intimate History of the Black Death by John Kelly

All amazing books. Good luck with your career.  (+ info)

How does a person catch infectious diseases?

What are the main causes by which a person catches infectious diseases such as aids, cancer, kidney infections, spleen disorders etc? Whats the easiest way to catch a disease?

Very complex question. Some disease are genetic, some are unknown, some are caused by a single mutations in the DNA. Infectious diseases are spread by the bacteria, viruses, fungi etc that cause them and are spread by various routes (sneezing, blood, fecal oral route, contaminated food etc). The easiest one to catch is a cold virus--have someone sneeze your way.  (+ info)

How long does HIV live in semen and is dried positive semen still infectious?

Hey guys have a question for you. Does anyone know how long HIV-positive semen is still infectious in a dried state?

Say, as a hypothetical, there was dried HIV-positive semen on upholstery and it has gone uncleaned with any disinfection products. How long would it have had to dry and the virus die for someone with an open wound to come in contact with that upholstery and there be no risk of infection?

Any help would be greatly appreciated!

the HIV virus dies as soon as it comes in contact with oxygen

and michael has no idea what he's talking about  (+ info)

Hauntavirus: How long does the virus remain infectious in the environment?

If there are known recent rodent droppings, for how long is the virus "active"? Please site your source or a website. All the sites I have found do not want to give this information specifically and warn to treat all rodent evidence as if it were infectious. I live in a rural area with a burgeoning dear mice population.


Hantaviruses belong to the bunyavirus family of viruses. There are 5 genera within the family: bunyavirus, phlebovirus, nairovirus, tospovirus, and hantavirus. Each is made up of negative-sensed, single-stranded RNA viruses. All these genera include arthropod-borne viruses, with the exception of hantavirus, which is rodent-borne.

Like other members of the bunyavirus family, hantaviruses are enveloped viruses with a genome that consists of three single-stranded RNA segments designated S (small), M (medium), and L (large). All hantaviral genes are encoded in the negative (genome complementary) sense. The S RNA encodes the nucleocapsid (N) protein. The M RNA encodes a polyprotein that is cotranslationally cleaved to yield the envelope glycoproteins G1 and G2. The L RNA encodes the L protein, which functions as the viral transcriptase/replicase. Within virions, the genomic RNAs of hantaviruses are thought to complex with the N protein to form helical nucleocapsids, which circularize due to sequence complementarity between the 5' and 3' terminal sequences of each genomic segment.

Dependent on environmental factors Temperature moisture ect.
it's possible to lay dormant for years!  (+ info)

What steps to take to become an Infectious Diseases diagnostician?

Can someone tell me the exact steps to become an Infectious Diseases diagnostician? I kinda know what to do, but I want to know the exact thing. I plan to go to college and medical school in Canada.


4 years of undergrad
4 years of medical school
3 years of Internal Medicine residency
Infectious disease fellowship (1-2 years)

You'll need to take the MCAT to get into medical school, as well as getting good grades (3.6+ GPA). You'll also take a multi-step licensing exam as well as specialty board certification exams. Good lucm,  (+ info)
