Recently I bought a sun protection cream from a health food store. The cream claims to provide sun protection (it's labeled SPF 15) by a plant complex made of PABA, willow bark extract, myrtle and myrtus leaf extract. It says that myrtle and myrtus leaf help protect from both UVA and UVB.

My questions are as follows:

1) Can this PABA complex provide the sun protection it claims (SPF 15 for both UVA and UVB rays)? The reason I am asking this is because until now I had only heard of sun protection by titanium dioxide or chemicals like octyl mexaoxycinnamate (did I get it right?). So I am curious to find out.

2) I notice a slight burning sensation in my eyes after I apply the product on my face. Is it true that PABA is a common irritant? (Since I notice many products proudly claiming PABA-free I wonder if it's really not good for you.)

Please help. I hope this question falls within your realm of expertise. After all, you are the 'know it all' around here, aren't you?

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 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 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.

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.

Can I use deodorants on my penis?
