When is a person with a cold contagious? A couple of friends, who are put off when I keep my distance from their sneezing and coughing, insist one is only contagious a week or so before symptoms appear. In the back of my memory is the idea that one remains contagious until a few days *after* primary symptoms disappear. I'm not usually so concerned about this, but I'm coping with a couple of other annoying health problems and want to try to avoid adding a cold or flu, to boot. I do the usual things news shows recommend — eat well, wash hands frequently. But when should one avoid others who have colds, or when should one stay isolated at home when one has a cold (or flu)?

I've been hearing a lot on the news about the new virus [novel coronavirus, COVID-19] and I'm seeing students on campus wearing masks. The news seems to have conflicting information and I'm not sure what to do. Should I be worried? Do I need to wear a mask too? Thank you.

1) I'm a college student and I've heard in the media that meningitis vaccine shots are recommended. How do I get more information and a shot?

2) As a parent of a college freshman this fall, I was concerned about the increasing publicity that Meningitis has received recently over the networks. Since the population most likely to be infected includes young adults living in close quarters, do you recommend vaccination and where is it available?

So I'm wondering some stuff about mpox. Why is mpox being spoken about as if it's a gay STD? Mpox can be spread through nonsexual contact and fomite transmission, according to health authorities, and many other diseases such as the flu and corona can be obviously spread through sexual intercourse (via close contact). Additionally, according to the CDC, Ebola can be spread through semen of a previously infected male a while after recovery while not symptomatic (which appears to be unlike mpox in which it's only spread while actively symptomatic and, although mpox is extremely severe, it doesn't last for more than several weeks) but Ebola isn't thought of as a STD (and of course Ebola can obviously be spread through nonsexual as well as sexual contact) just like corona and the flu among many other diseases. Yet mpox is basically now thought of as being a STD — and a gay STD at that — whereas other diseases that also spread through nonsexual means like mpox aren't. This is very concerning to me both because it would be contributing to ineffective containment measures which would let mpox continue spreading and because it could lead to an increase in discrimination against an already marginalized demographic. What's going on here?

I've read your info about sagging breasts and whether to wear a bra, etc., but you don't say anything about what one can do after pregnancy after the skin is stretched out. Please tell me surgery is not the only answer!

My partner is always getting colds, sinus infections, and other nasties during cold and flu season. I've seen him through strep throat, stomach flu, and 16 months of sinus infection flare-ups. It's important to me to take care of him when he's ill, and I know he appreciates the help, but during the school year I get nervous about the risk to my own health and the potential for missing classes/work. What are some ways (short of wearing a mask...) to keep myself from catching all of his bugs without leaving him sick, sad, and lonely?

Why is your favorite food very tasteless when you have a cold?

I love sushi, sashimi, and oysters on the half shell. I apparently am uneducated (ignorant) when it comes to the health risks associated with eating raw seafood. I read in an article that a person could contract hepatitis A and worms. Is hepatitis A something that is "curable"? Are ANY of the diseases/problems associated with eating raw fish NOT "curable?"

I've come down with chickenpox. Should I stay home from classes even though 90 percent of adults have already had it and are thus immune? If I take great care washing my hands and avoiding coughing anywhere but into the crook of my arm, will I be reasonably assured of not spreading it?

My breast implants were implanted in my body when I was 22 years old. I am now 64 years old and an MRI shows leakage. I am really afraid of having them removed. Am I in danger if I continue with them until I die?

A friend of mine is living with someone who might have just got measles (results pending). If true, and my friend has also got it, how contagious is it? I think it is measles, rather than German measles, which I had as a child. Does past illness provide any defense? That is, can you get it twice? I presume having had German measles does not provide any protection against measles.

How is it transmitted? Like a cold? (Physical contact, common contact with hard surfaces, and maybe airborne?)

Is there any way to make your breasts bigger without surgery? I heard that you can take pills but I don't know the side effects or if it even works. What are the bad things that could happen if I took the pills to get bigger breasts?

1) When you are at the gym exercising do you need to wipe down each machine that you use even if you are not sweating?

2) I'm looking for some helpful pointers you might have on the subject of health club etiquette (i.e., don't wear perfume because others will leave workout equipment wearing your perfume). I would appreciate anything you have to offer on the subject.

I know that herpes are only supposed to appear on the mouth or genitals, but is it possible for them to occur elsewhere, as well, such as the shoulders or legs? I ask because I believe I might have genital herpes, but am unsure if this is the case as the "herpes" are not confined to my genitals/butt/thighs, and are appearing on my shoulders and lower legs.

Is it o.k. to not wear a bra? I haven't worn one for over a year now and I hope to never again! Is it really healthy to wear one? Will they "sag" quicker if I don't? Please tell me I can burn my old bras!!!

I was recently diagnosed with impetigo & was wondering if I had oral sex with my boyfriend if he'd get genital herpes. Thanks!

Is it safe to have oral sex when either partner has a canker sore — not a cold sore, but a canker sore? Does the same virus cause both and can you cause genital herpes with a canker sore?

During sex, my husband likes to squeeze and suck my nipples. I enjoy this, but am worried that this type of pressure on the nipples may cause problems later on: we are planning on having a baby in a few years, and I want to breastfeed. Might the pressure of squeezing and sucking hurt my mammary glands and ducts, making it difficult or impossible for me to breastfeed?

I'm HIV positive, very low viral load & great t-cell count (not on meds). I've been reading recently that flu shots aren't all they're cracked up to be. What are the dangers of a flu shot, and if my immune system is already doing well, should I still get a flu shot?
