what are some ways infectious diseases can be spread?

That depends on the specific disease. There's coughing on someone, sharing saliva, blood to blood, sex, touching something that a sick person has touched and not washing your hands, drinking after someone. Usually the diseases with the highest morbidity or mortality rates are not so easily caught as touching the same things as someone else, so I wouldn't worry too much about that. It really depends on what kind of disease you're talking about, your question is not real specific.\nHIV is spread through sex or blood to blood. Typhoid can be spread, for example, by someone using the restroom and not washing their hands, and then preparing food. Colds and Flus are spread by coughing on someone or touching someting that a contagious person touched and not washing your hands. There are STDs you get from sex.\nThere are a lot of ways to get diseases from other people and animals. Being bitten by an animal too.\nYou can get certain diseases by drinking milk that has not been pasteurized. There are so many ways, and so many diseases. Click on the link for more information.

Animals can sometimes carry infectious organisms which don't cause them to be sick, but which can infect humans. \n\nTurtles, for instance, often carry salmonella. As do many reptiles and amphibians. Poultry does as well, which accounts for advice to cook chicken very well. \n\nWild mice in the N American SW desert can carry and spread to humans a family of viruses called hanta virus (originally found and identified in Korea). In fact, rodents generally (or rather their fleas) are the carriers of bubonic plague. \n\nAll that said, contaminated food is ordinarily handled more or less safely. The intensely acid conditions in the stomach don't really contribute much to digestion, but are lethal to most bacteria. This is why less than sterile food circumstances in some places don't lead to widespread death from the contamination. It does cause a more or less continuous low grade of food upset and such, and in some cases some very bad diseases (such as cholera). But even if not perfect, stomach acidity does a pretty good job of keeping us safe from most contamination infection problems.\n\nIt may be that your guys lout of a co-worker will get sick, but probably not. A better choice would perhaps be to only bring some fruit for lunch -- perhaps the bully wouldn't want to steal a half-eaten apple?

There is no proof for such possibility. The virus has a very weak environmental susceptibility and is not able to be transmitted via contaminated surfaces. Modes of transmission are sexual, vertical, blood or blood components transfusion, broken skin+infected blood and contaminated needles used by injection drug users.\nThe disease is diagnosed when an opportunistic infection e.g. P Cranii P or malignancy e.g. K. Sarcoma are detected, HIV antibodies in the blood and the increased numbers of T cells in the blood.

The HIV virus will die pretty easily on its own - it cannot survive outside body fluids. This is fortunate, because there are very few ways it can be transmitted. Bodily fluid exchange (sexual contact, needle sharing, mother to fetus, etc) is really the only way.

sure you can!,  Anything can become infected.  If you have a red area, warm to touch, painful and its spreading go to the doctors. You may need meds.  Good Luck.

No- you would not be able to get an infection this way- it would have to be bodily fluids directly from the infected person to the noninfected person.

It is possible to transmit AIDS by saliva but not very often.  It's more often transmitted by blood or sexually.  AIDS is an STD.  People often transmit it by using already used needles.  It's more likely to be transmitted by kissing if you have an open wound in your mouth, like a cut on your lip.

Blood, germs, viruses. Think it twice. It takes a hell of a long time.

The Human Immunodeficiency Virus (HIV) which causes AIDS is transmitted through body fluids in particular blood, semen, vaginal secretions and breast milk. Transmission of HIV takes place in four ways: \nunprotected sexual intercourse with an infected partner (the most common); \nsharing needles when injecting or other use of contaminated injection or other skin- piercing equipment; \nblood and blood products through, for example, infected transfusions and organ or tissue transplants, \ntransmission from infected mother to child in the womb or at birth and breastfeeding. \nHIV is not transmitted by casual physical contact, coughing, sneezing and kissing, by sharing toilet and washing facilities, by using eating utensils or consuming food and beverages handled by someone who has HIV; it is not spread by mosquitoes or other insect bites.

Unlike bacteria that multiply in the correct conditions of their own volition, viruses have to invade a cell and change it to spread.  They can't just be, they have to take something over.

No, AIDS can only be transmitted by blood or semen. It also cannot live long outside the human body, and can be killed easily with simple everyday disinfectants. Unless there was blood all over the doorknob and you cut your hand open while opening it and rubbed your wound into the blood there's nothing to worry about.\n\nBlood or semen. That's it.

The key is for certain bodily fluids to be exchanged between two people -- one of whom has HIV.\n\nMajor ways include:\na) Unprotected sex (certain types are riskier than others).  This includes M/M (probably highest risk), F/F and F/M (probably the greatest current source of spread).\nb) Blood transfusions in the early 80s (not now);\nc) IV drug abuse with shared needles;\nd) Accidental exposure of health care workers (needle stick, surgery nick)\ne) HIV positive moms to newborns.\n\nOther ways that are, at least in theory, possible (if very rare or undocumented): \na) contaminated medical instruments (there is thought to be one case in Florida with dental intruments that had not been properly sterilized)\nb) Any other fluid exchange.  For example kissing is thought to be very low risk.  OTOH, if both persons had open wounds inside the mouth...\nc) Blood to blood contact (i.e., boxing).

I just copied this:  \n\n"How is bacterial meningitis spread?"\n\n"Fortunately, none of the bacteria that cause meningitis are as contagious as diseases like the common cold or the flu, and they are not spread by casual contact or by simply breathing the air where a person with meningitis has been.  The germs live naturally in the back of our noses and throats, but they do not live for long outside the body.  They are spread when people exchange saliva (such as by kissing; sharing drinking containers, utensils, or cigarettes)."  \n\n"The germ does not cause meningitis in most people.  Instead, most people become carriers of the germ for days, weeks or even months. Being a carrier helps to stimulate your body's natural defense system. The bacteria rarely overcomes the body's immune system and causes meningitis or another serious illness."

This is not a mode of transmission of HIV.In ur case,HIV cannot be transmitted becoz,\n1.The HIV is very sensitive and cannot live long when exposed to air.\n2.Your skin acts as an effective barrier.\nRemember Infection due to HIV occurs through:\n1. Unprotected sexual intercourse with an infected partner. Regular and consistent use of condoms during sexual intercourse means protected sex and minimizes the chances of getting HIV and other sexually transmitted infections.\n2. Transfusion of infected blood or blood products.\n3. Use of infected needles as in injecting drug use or in health care settings.\n4. From mother to child.\n\nIf u are still very anxious,get urself tested.

Viruses enter your body from other bodily fluids, whether it be blood or saliva, excrement or vomit.  Viruses generally travel easier in the medium they affect, AIDS is blood-borne, and while it's possible a blood to blood transfer would infect you with a common cold or flu, it's generally spread by saliva. Generally viruses cannot survive for long outside of a host organism.\n\nYour body is under attack by viruses constantly, many times you will receive a virus and not even know because your body is able to fight it off before it can affect you. Besides the obvious, visible or physical symptoms of an infection, a doctor can test for anti-bodies to see if you've been infected. The main reason we give vaccinations is so your body can fight off a weakened or dead virus and learn to make the anti-bodies to defeat it for the next time you are infected by it. However some viruses can remain dormant for long periods of time and even tests cannot show their presence, since the viral load (amount of virus particles) is so low.  \n\nOn a side note, contrary to what was said above virus are NOT organisms. By the definitions of life it is not alive, technically it is an obligate intracellular parasite. This is for a few reasons, but the big ones are that they are not cellular based and they cannot reproduce (by themselves). They do share characteristics with living things, such as the use of DNA/RNA and the ability to evolve.

Yes! There are a lot of STDS you can get by skin to skin contact or rubbing.\n\nIf a person has genital herpes you can get it by rubbing genital areas together. Even if the person is not having an outbreak, they can be shedding the virus after the sores have disappeared. \n\nHPV is another STD you can by rubbing genital areas together. If the person has genital warts (caused by HPV) and the other person rubs up against them, they can contract HPV.\n\nCrabs (Pubic Lice) is also spread by direct skin to skin contact (like rubbing).\n\nChancroid is another STD that can be spread by direct skin to skin contact.\n\nGonorrhea (Clap) can be spread by any very close physical contact.\n\nScabies can be spread through close contact or through sleeping in bedding or wearing clothes that are infested. Rarely, holding or shaking hands can transmit scabies.\n\nSyphilis can be spread by intimate touching or kissing.

AIDS is the disease caused by the HIV virus.\n\nYou can get infected with HIV if the virus passes into your body from someone else who is already infected.\n\nThere are two main ways this can happen:\n\n1. Through having unprotected (no condom) vaginal or anal sex with someone who has HIV. Oral sex carries a small risk of transmission. There has never been a reported case of transmission through kissing (even deep kissing).\n\n2. Through someone else's infected blood getting directly into your bloodstream, for example through sharing drug or tattoo needles or injecting equipment, or piercing with unsterile equipment. In the first half of the 1980s a number of people were infected from contaminated blood transfusions, but this is very rare now because blood donations are screened. Sometimes HIV is passed from an infected mother to her foetus either in the womb or during birth.\n\nYou CANNOT get HIV through normal non sexual contact, or from sharing eating utensils or from mosquitoes.
