Yes, type O is the universal blood type. They can donate to anyone. Their blood cells do not contain the type A or type B proteins on their surface. For people who have type A blood their red blood cells contain only the type A protein so if they were to recieve type B blood, the type A will see the type B as invaders and try to destroy the type B blood. This is because they do not recognize the type B protein because their cells do not have it on their surface. Type O does not have any type A or type B proteins so type A blood cells will accept it.

Only if you pick up a sexually transmitted disease. So, as long as you take precautions, yoou should be okay.

Do not become orally intimate with someone's nether regions, (just in case you were thinking of doing that) with a cold sore. I was just at the doctor for the cold sores that I get on my lip and they informed me that yes in fact you can spread the virus that way. Don't obsess, stress can make them worse and cause them to come out more frequently. If you get them on a semi regular basis, go to a clinic or your regular doctor, they have an anti-viral pill that will help you greatly. Abreva and such only dry out the blisters, so does ear wax believe it or not. Most adults have the herpe virus in their system, but a smaller percentage have symptoms. Ice also breaks the virus down quicker once you have the blisters, and aspirin will reduce pain and take the swelling down. Don't ever break the blisters they are freakishly contagious. Other than that, relax, they're a pain in the ass, but unless you have a problem with your immune system, you'll live.

Yes it is, sometimes very contagious.  However, before you put on a mask to walk outside, most people are able to fight off the microbes before it puts them in the hospital.  Use common sense.

That is actually not known.  Scientists know that it is contagious, but they don't know why.  My guess is that it's physiological; people follow one another.

Its only contagious as long as the person is running a fever. Once the fever has stopped its ok. Besides those with mono are quartined until they are no longer able to spread it. If he had it in January odds are you are safe.

Yes. Please use protection and be careful, you could not only spread it, but also catch something else.

No, a man with type AB blood can NOT have a type O child... The way blood types work is that A and B are surface markers on the red blood cells that are inherited. Type O means that there are NO surface markers. A and B types are codominant (i.e., both dominant) over type O.  So...if your father has an AB blood type, your brother MUST be either A or B or AB for this man to be his genetic father...he can NOT be O, no matter what your mother's blood type is.  The genetics are thus:\n\nIf Dad is AB and Mom is O: the possibilities for the children are AO or BO (type A or type B).\n\nIf Dad is AB and Mom is A: possibilities are A, B or AB.\n\nIf Dad is AB and Mom is B: possibilities are A, B or AB.\n\nIf Dad is AB and Mom is AB: possbilities are A, B, or AB.\n\nP.S.--Just because it's not possible for your father and brother to be related, that doesn't necessarily imply that your mother is a bad person...it just means she made a serious mistake in being unfaithful.  Don't let that influence your love for your brother.

Food poisoning is caused by bacteria in the food, so no, it is not contagious.

I hope it's not contagious. Don't couch or sneeze on your PC, please.

The best advice I can give you is to relax, enjoy yourself doing what you like to do, and it's contagious. People see you having fun, and enjoying yourself, they want to do the same thing. Before you know it, there's a lady of like-mind beside you, and slowly but surely , you hit it off! Patience is the key, and relaxing. It WILL happen! Good Luck!!

Yes.  It is possible for a type O mother to produce antibodies that will cross the placenta and attack her baby's cells if her child carries either the A or B (or both) antigen.\nUsually antibodies against A and B are IgM - they are too large to cross the placenta, but type O people occassionally produce an IgG antibody (called anti-A,B).  This is the antibody that usually does the damage.\nThe baby has a chance for being type O (between 0 and 25%), and in that case there's no problem.  However, there's a 75 to 100% chance that the baby will be type A, so there could be a problem.\n\nThe chances of a type O mother's immune system attacking her baby's blood because of this anti-A,B antibody are rare, but in cases were a female is type O (especially if she's Rh positve), it is investigated along with other possible causes.

yes\n\none parent is blood type A+, and the other is B+.\n\nTherefore, can be represented as AO, and BO.\n\nin this way, it is possible to have an AB, AO, BO, and OO blood type, more commonly known as AB, A, B, and O

Yes, and transmission through sexual contact is the most common form of transmission for adults...so play safe.

I don't know Johnny, but if he's still sneezing and wheezing, I would bet he is still contagious.  They are spread by respiratory droplets, which are produced by sneezing or coughing, also by getting these on inanimate objects, and then you touching them, and then touching your nose or mouth or food.  There are many strains of colds, which is why we keep getting them, but I think the older you get, the less you get them, because you may have had them before, or they get less severe, because you have had one quite similar and have some immunity.  Of course every one who sneezes or wheezes doesn't have a cold.  They could have an allergy or asthma or they could have rhinitis from being a coc addict or a meth addict or some people have rhinitis medicamentosa, which is rhinitis from using too much nasal decongestant spray like Afrin.  It's normal to sneeze in response to cold air or dust or allergens.  It's normal to do a little coughing and smokers do this much more.
