What are the actual differences between infectious diseases and contagious disease? Any answers appreciated!

(So always good to practice hygiene!). Whereas infectious diseases encompasses all that PLUS other diseases caused by 'germs' that may not necessarily be contagious: for example those deadly amoeba that kill kids every summer, Lyme dz etc. ...Read more

How can I tell the difference from fordyce spots or other non contagious skin diseases from an STI. I am quite certain the spots on my penile shaft an?

Easy: just look!: Fordyce spots are normal skin glands. Google it for photos; if yours look similar, that's what you have. There is no STD that looks like them. If in doubt, get professional care. Australia's federal sexual health centres are the world's best network of STD/HIV clinics. You'll never go wrong with care at your local SHC. (If in Sydney or Melbourne, your local clinics are the best of the best.) ...Read more

Skin flora: Staphylococcus haemolyticus and staph saprophyticus are bacteria that live on the skin. When they're found in the urine in a man, it's usually because of contamination from the skin of the penis during the process of peeing into the cup. It's not an infection, not contagious, and nothing to worry about. ...Read more

We have very few successful antiviral a but we do have for the herpes class viruses. There are different doses for treatment and for suppression. Speak to your doc! ...Read more

How to tell the difference between food poisoning and stomach bug? Only vomited once after eating bad meat, not sure if contagious.

How to tell the difference between food poisoning and stomach bug? Only vomited once after eating bad meat, not sure if contagious.

Diarrhea: Usually if you have a stomach bug or gastroenteritis you will also have diarrhea. Especially if you have bloody stool that is an indication of a gut infection. However, if you have vomiting alone and quick improvement that is more likely "food poisoning" or bacterial toxins in your food. I would throw out the bad meat and make sure to wash your hands well since gut infections are very contagious. ...Read more

Additionally, as we explore different areas in the world, we will expose ourselves to new diseases. ...Read more
