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?
