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.

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)?

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?

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 been swimming a lot this summer and I have noticed a green tint to my blond hair. Is this caused by previous dyeing? Is it possible to remove the green tint? Thanks for your time.

I have dandruff that responds well to over-the-counter shampoo. Ergo, I have been using the stuff almost exclusively for ten years. No brand in particular, sometimes zinc pyrithione (the blue stuff!), sometimes coal tar (the smelly brown stuff!). Anytime I switch to non-dandruff shampoo for like three to four days straight, I get my dandruff back. I worry that I might be addicted to dandruff shampoo. Should I worry?

Ever since high school, I've had very oily hair and skin, but it became worse in college. Now I'm in my mid-twenties and have to shampoo my hair about 10 times each day to get it clean. Then by evening it's already oily again. This isn't my scalp trying to moisturize itself after being over cleaned, because I've tried not washing it completely and it's even oilier the next day.

Are there any special shampoos or medications that help reduce oily skin? I've tried some facial products from my dermatologist, but they haven't reduced the oil production. This is an embarrassing problem and limits the overnight activities I can do, like camping or staying with friends.

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?

I was wondering what causes fingernails to turn yellow if you leave nail polish on for a long time. Is it bad? And what can you do about it?

The last time I was at the hair cutting salon, the person who washed my hair asked me if I washed my hair everyday. I said I did, and she said she could tell. I'm not sure what she meant by this, but please tell me how she could determine this, and what is the best overall practice for washing hair in terms of frequency. I'm interested in the health of my hair as well as the health of my scalp. Thanks for you help!

How do I know if my hair is oily or dry? Does it make a difference if I'm a guy with short hair?

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?)

What are the reasons for getting white hair in teenagers?

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.

My wife has noted that she is recently losing hair at a much greater rate than normal. She feels her hair is significantly thinner (less density of strands) than in the past. What could be the cause of this?

My fingernails fray and chip all the time. I have tried many different nail polishes and nail hardener but nothing helps. I've been trying to grow my nails for the past year and I just can't seem to get them to grow. My mother and older sister don't have any problems getting their nails to grow. Please give me some tips on how to make my nails grow stronger and fast.

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

My girlfriend and I were wondering about dying her pubic hair. Is it okay to use regular hair dye or are there special products to use for it?

I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?

1) I was born with thick and coarse hair. It all sticks up when it is short. I lose confidence when I notice that people always look at my hair. Is there any way I can make them softer? Will medication help?

2) I seem to have very untamable hair. I keep the hair on the side of my head really short because of this. It's not that my hair isn't uncombable or anything like that, but if the hair on my sides grow even the slightest they start sticking out at 45-90 degree angles to my head, and there is nothing I can do about (I've tried everything but STIFF STUFF....). I look at other people's hair and they don't even need to blow dry or comb it and it sticks firmly to the sides of their heads. Is there a reason why some people have such easy control over their hair? Is it something I'm eating or doing wrong? Thank you for any advice!

I have taken three Depo-Provera shots. My hair started falling out excessively several months ago. In looking for answers I found out that this is a side effect to the shots. I was not informed of that before I took the shots. I saw in one of your Go Ask Alice! answers that depo-provera suppresses the Follicle Stimulating Hormone and the Luteinizing Hormone. What is this hormone? Is this what makes my hair fall out? And do you know if there is anything I can do to stop it? My next shot is due by May 15 but I am not going to get it. 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?

What is up with this new trend of putting food products like olive oil or avocado juice into hair? Is it more healthy than using shampoo?

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?

I have a problem. I am a 21-year-old male with the face of a 15-year-old. What I mean is that I am unable to grow facial hair. I was late starting puberty and it has left me underdeveloped. My baby face is affecting people's trust in me, especially at my job. I am constantly referred to as the kid and I feel that I am never really taken seriously. I am wondering if there are any types of drugs that can possibly aid in my facial hair growth problem and, if there are, what are the side effects? Please help me. I am sick of being a man trapped behind a child's face. Thank you in advance.

I have been a vegetarian for two years. Since last year, I have been losing quite a bit of hair. I have no pattern of male baldness in either side of my family. I do take multi-vitamins everyday. My diet is fairly nutritious. Could there be any correlation between my vegetarianism and the hair loss? Some books point to folic acid deficiency so I have made an effort to buy vitamins with 100%-200% RDA recommended folic acid. Do you have any ideas on what might be causing this?

Seems like the only health risks you read about in the news is from eating tainted fish or from getting an infection when swimming in the ocean. Are there other direct effects on our health posed by pollution in the ocean?

Is it dangerous to wax or use a chemical depliatory such as Nair on areas of the skin that have moles? I've seen warnings on some labels regarding this. What could happen to the moles?

Both my boyfriend and I have warts on our hands. Can these warts be transferred to our genital areas?

My cousin's biology teacher told her class that the water we shower in is not hot enough to actually kill bacteria but it promotes bacteria to grow through its warmth. He said it is best to take as cool a shower as one can stand. Is this true?

I am curious as to whether the nail bed regenerates or not. I used to bite my nails, and slowly I've bitten off some of the nail bed as well, on all ten fingers. It has been two years, and the nail bed does not seem to grow back, and my nails grow according to the new shape of the nail bed. It makes my hands look somewhat ugly, to be honest.

Any suggestions would be appreciated.

I would like to know the reasons for excess facial hair. Are there any solutions for it? How safe is electrolysis?

1) I have a really embarrassing problem... I have hair on my chest and I am a woman! It's not really thick, but it's very noticeable, and I hate it! Is this a hormone problem or is it normal? Please help, 'cause to me, it's gross and I will do anything to get rid of it. I have been shaving it, but it just grows back within a few days or so. Please help!

2) I am a 24 year old female and for the past few years I have had facial hair. I tend to get it on my chin and the side of my face. It is usually light but you can feel it, and I will never let my boyfriend touch my face unless I have just shaved it.

I don't want to go for laser treatment, is their anything else you could suggest? I feel disgusting and very unwomanly.

I was wondering about the chemical sodium laureth sulfate. I have received several forwarded e-mails about this causing cancer by a lawyer looking into the matter. This chemical was said to be in many shampoos to create a nice lather, but it's actually a garage cleaner and is a cheap substance for the manufacturer, and in the past, only 1 in 2000 would get cancer from this, and now it's about 1 in 10. I was just curious if it really causes cancer, or is it just a prank? And if it really does cause cancer, what kind of cancer is it? Thank you. I would appreciate an honest answer.
