Fearful? No. It is respect for what some diseases can do. Being fearful could make one an ineffective health care provider. But, having an understanding of the diseases and how to protect yourself and the patients can overcome whatever fears you might have.
Of course there are some days you do go home and give your family an extra hug...after you have thoroughly showered.
Thats why I put it in quotes. I have no fear of it; people were responding to my post like I did. I just have an understanding and respect for what viruses do, which I assume you do too.
