Odor originating from the vagina. It's normal to have a slight vaginal odor,t with stronger and more subtle variations of individually-unique smell appearing during different parts of menstrual cycle. Normal odor is somewhat salty, yeasty, resembling sour milk, even a little bit fishy or onion-like, more so if eating onions and garlic, meat and drinking coffee. 
But, a strong vaginal odor — for instance, a strong "fishy" smell — might be abnormal and could indicate a problem. Other odors could be acidic, like vinegar, ammonia, garlic, cheese, body odor, urine, bread, bleach, feces, sweat, metal, feet, garbage, and rotten meat.
An abnormal vaginal odor is usually associated with other vaginal signs and symptoms such as itching, burning, irritation or discharge.
Common causes of abnormal vaginal odor include Bacterial vaginosis, secondary TMAU (around periods), Poor hygiene, Retained or forgotten tampon, Trichomoniasis. Less commonly, abnormal vaginal odor may result from rectovaginal fistula,  cervical or vaginal cancer

The invasion of an organism's body tissues by viruses leading to cellular damage or death, immunopathology or cell transformation (e.g. into a cancer cell).  Flu caused by influenza viruses is the best known viral disease. 

Viruses are spread (transmitted, mostly from other humans but also via- or  from animals) in various ways. They can be swallowed, inhaled, spread by the bites of insects, such as mosquitoes, certain biting flies, or ticks, spread sexually or during transfusion of contaminated blood.
Common viral infections (flu, measles, rubella, chickenpox) may be diagnosed based on symptoms.

​any kind of vision loss, from temporarily weakened, low vision to blindness.  "Normal" vision is 20/20 or 6/6. Individuals with superior vision can be as good as 20/10 or 6/3 which means that they can see as a young person with normal vision at twice the distance (20 feet vs 10 feet and 6 meters vs 3 meters).  Vision is impaired when the best-corrected visual acuity is less than 20/40 or 6/12 in the better-seeing eye.
