Brief Answer:
Contagious with onset of symptoms

Detailed Answer:
Hello,
Thank you for the query at HealthcareMagic

Cold sores are contagious from the onset of symptoms like tingling,burning,redness etc to the time they heal completely . They are highly contagious once you develop blisters.
Since you shared the harmonica yesterday there is a possibility that your son might have been infected.

Brief Answer:
Asymptomatic shedding of virus poses very little risk of transmission

Detailed Answer:
Hello,
Thank you for the query

I understand your concern. But even though you were aymptomatic there is still a very little risk of spreading the infection especially since you were so close to developing symptoms.
Transferring the infection without symptoms is called asymptomatic shedding. But the risk is very little and the possibility of your son developing the symptoms are very slim.

Hope I was able to help you

I thought I had a UTI, but they told me no bacteria in urine test Here are the symptoms, some may not be related. For several years now I have had a little semen discharge whenever I am constipated and have a hard bowl movement. After reading online, I assumed I had an enlarged prostate and that the discharge was from that, coupled with being obese. Over the past month or so, I noticed a bad smell to my urine that reminded of when I helped care for my grandmother when she was old. I also would feel like I had to go to the bathroom to urinate or like I was going to pee my pants after I already went. In addition, the tip of my penis was a little tender and red, and the inside of the hole was red also. I immediately thought I probably have UTI, so I went to the doctor. They did a quick test in the office to a urine sample and said, no bacteria, but they would send it out for a more complete analysis. Still no results. So I didn't have to wait, they gave me a prescription for Bactrim and told me to take it for 3 days. I did that and the symptoms never went away. Help. More info on me: I haven't had sex in 7 months. I take atenolol for high blood pressure I take omeprozole for GERD I have also been taking phentermine for 2 months to lose weight I sometimes take an OTC called melatonin to help me sleep I also take Valtrex occasionally for cold sores I also take a daily multi- vitamin

I had a pyruvic peel done 16 days ago. I had a very bad reaction. The day after the peel I looked as though I was a burn victim. I have healed but I still have a few areas of reddness. The dermatologist said that I had cold sores on my face, and this created an infection. I have never had cold sores so this is shocking to me. Anyway she prescribed Locoid cream and Cicafate to use twice a day. I am seeing her again in 2 weeks. Is the reddness likely to heal??????
