Congenital Syphilis

Congenital syphilis is an infection transmitted from mother to child during pregnancy and/or delivery caused by the bacterium Treponema pallidum. Congenital syphilis can cause severe illness in babies including premature birth, low birth weight, birth defects, blindness, and hearing loss. It can also lead to stillbirth and infant death. Tests and treatment for pregnant women are readily available. Over the last several years, California has experienced a steep increase in syphilis among women and congenital syphilis.

West Nile Virus

WNV Cycle


What is West Nile Virus

West Nile virus (WNV) is a mosquito-borne disease that was originally found in Africa. It was first detected in the eastern United States in1999; since then the virus has spread across the continental United States and is well established in most states, including California.

How do People Get WNV?

Most often, WNV is spread by the bite of an infected mosquito. Mosquitoes are WNV carriers ("vectors") that become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite. 

How can I reduce the risk of being infected with WNV?

CDPH recommends that individuals prevent exposure to mosquito bites and West Nile virus by practicing the "Three Ds": 

1. DEET - Apply insect repellent containing DEET, picaradin, oil of lemon eucalyptus, or IR3535 according to label instructions. Repellents keep the mosquitoes from biting. DEET can be used safely on infants and children 2 months of age and older. 

2. DAWN AND DUSK - The mosquitoes that transmit WNV bite in the early morning and evening, so it is important to wear proper clothing and repellent if outside during these times. Make sure doors and windows have tight-fitting screens to keep out mosquitoes. Repair or replace screens with tears or holes. 

3. DRAIN - Mosquitoes lay their eggs on standing water. Eliminate or drain all sources of standing water around homes and properties, including buckets, old car tires, rain gutters, birdbaths, and pet bowls. If a swimming pool is not being properly maintained, please contact the local mosquito and vector control agency.
