Disease, Please: ____________ “When I get a cold sore, I put Carmex on it, because Carmex is supposed to alleviate cold sores. I don't know if it does help, but it will make them more shiny and noticeable. It's like cold-sore-highlighter. Maybe they could come up with an arrow that heals cold sores.” – Mitch Hedberg Images: HSV-1 lesion, PHIL #1573; Mitch Hedberg, W i ki; Herpesviruses, PHIL #2171.

Most colds causes by Rhinoviruses (genus) and Coronavirus (a group within a genus). But more than 200 different viral types can cause colds. That is why vaccination not practical.

Spreads from infected persons through air-borne droplets, direct contact with nasal secretions or fomites. 2. Infects cells of the nasal and adenoid mucous membrane. 3. Trick infected cells into making more cold viruses, which are then transmitted as you sneeze or touch things with hands contaminated with nasal secretions. 4. When your body catches on, inflammation occurs as body tries to rid itself of virus. It's at this point that you get fever and other cold symptoms. SYMPTOMS: Sore throat, runny nose, nasal congestion, sneezing and cough; muscle aches, fatigue, malaise, headaches, muscle weakness, and loss of appetite. (Fever and extreme exhaustion more commonly associated with influenza). COURSE: Symptoms usually resolve after ~ 1 week, but can last up to two.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
