  1. Electron Micrograph: Zika virus

    show more
    Description: This is a transmission electron microscopic (TEM) image of Zika virus, grown in LLC-MK2 culture cells, which is a member of the family Flaviviridae. Virus particles are 40 nm in diameter, with an outer envelope, and an inner dense core. Also note the smooth membrane vesicles, which are known to be the replication complex for this virus.

  6. Congenital Rubella

    show more
    Description: Congenital rubella - multiple dusky red purpuric patches and plaques over the body Congenital rubella syndrome (CRS) can occur in a developing fetus of a pregnant woman who has contracted rubella during her first trimester. If infection occurs 0–28 days before conception, there is a 43% chance the infant will be affected. If the infection occurs 0–12 weeks after conception, there is a 51% chance the infant will be affected. If the infection occurs 13–26 weeks after conception there is a 23% chance the infant will be affected by the disease. Infants are not generally affected if rubella is contracted during the third trimester, or 26–40 weeks after conception. Problems rarely occur when rubella is contracted by the mother after 20 weeks of gestation and continues to disseminate the virus after birth.

  9. Condyloma Accuminata

    show more
    Description: Condyloma accuminata over the scrotum, multiple whitish papules Genital warts (or condylomata acuminata, venereal warts, anal warts and anogenital warts) are symptoms of a highly contagious sexually transmitted disease caused by some sub-types of human papillomavirus (HPV). It is spread through direct skin-to-skin contact during oral, genital, or anal sex with an infected partner. Warts are the most easily recognized symptom of genital HPV infection, and types 6 and 11 are responsible for 90% of genital warts cases.

  10. Varicella

    show more
    Description: Varicella - vesicle on an erythematous base over soft palate An acute, highly contagious, viral disease, with mild constitutional symptoms and a maculopapular vesicular skin eruption; it is a common childhood disease and is rarely severe, but it can be accompanied by severe symptoms in infants and adults. It is usually spread by either contact with blisters or droplet infection, and the average incubation period is 10 to 16 days. The period of contagion lasts about two weeks, beginning two days before the rash appears. The causative virus is human herpesvirus 3 (formerly known as varicella-zoster virus). The same virus also causes herpes zoster (shingles), with the differences in the two diseases probably reflecting differences in the response to the virus. Called also varicella.
