A mild prodrome of fever and malaise may occur 1 to 2 days before rash onset, particularly in adults. In children, the rash is often the first sign of disease.

725598
The incubation period is variable. It occurs commonly around 4–10 days.
184559
The first outbreak usually occurs within a few weeks after infection with the virus. Symptoms tend to resolve within two to three weeks. The signs of an initial (or primary) episode of genital herpes include multiple blisters in the genital area.

The Zika virus' incubation period is about three to 12 days after the bite of an infected mosquito. The vast majority of infections are not contagious from person to person; however, it may be passed person to person during sex. conjunctivitis.

The first outbreak of oral herpes usually develops within about one to three weeks after infection. This initial outbreak may last for up to three weeks. With genital herpes, the first outbreak usually occurs within about two to 20 days. Similar to oral herpes, the initial outbreak may last as long as three weeks.
