HARRISONBURG, Va. (AP) _ A Harrisonburg mother of three has been diagnosed with the first known case of the Zika virus in the state. Heather Baker tells media outlets that she received a letter dated Feb. 1 from the Centers for Disease Control and Prevention confirming that she has Zika virus. Baker thinks she contracted the virus in November while on a mission trip in Guatemala. She says the first symptom was a swollen lymph node on the side of her head. She then began experiencing joint pain, a rash and body aches. Zika is transmitted from infected mosquitoes to people, from infected pregnant mothers to babies and possibly through sexual activity. Babies born to mothers with the virus can have birth defects. Baker says she is managing her symptoms and trying to be cautious.
