Glossary Term
A method for converting an individual score into a standard form. The z-score indicates how far and in what direction an item deviates from its distribution's mean, expressed in units of standard deviation. Calculation of a z-score requires knowledge about the population's standard deviation and mean.
Tests
A Zika virus test looks for signs of the Zika infection in your blood or urine. Zika is a type of flavivirus, as is dengue fever and West Nile . Like those viral infections , Zika is usually spread by mosquitoes , especially in areas with tropical climates, such as parts of Central and South America, Africa, Mexico, and islands in the Caribbean and Pacific. Because Zika can enter bodily fluids such as blood, urine (pee), and semen, it can also spread through sex with an infected person or from a pregnant woman to her fetus.
