attacks in that country. Back here at home. A major health alert tonight. The zika virus being spread by mosquitos right here in the U.S. At least four people infected after being bitten near downtown Miami. Today health officials going door to door to test residents and tonights a warning from England to its pregnant residents. Do not travel to Florida. Here's ABC's Eva pilgrim in ground zero. Reporter: Tonight that warning for pregnant british citizens not matched by the cbc here at home. This is the outbreak. Oh, my god. Don't tell lulu that. Lulu, you shouldn't be here. The CDC not putting any travel warning in place for Florida yet but this family of three now taking extra precautions. We would be more sensitive to keeping an eye out for symptoms. Reporter: Four people with zika all bitten by mosquitos in this one square mile of Miami right next to downtown and just one block from her home. This is my baby. This is him. She's 25 weeks pregnant with her first child and constantly on alert. Knowing she's most at risk. Zika symptoms are mild in most but can cause severe birth defects. I have to think every day do I want to go outside or what am I going to wear. Did I carry my repellant. Is it strong enough? Reporter: In Miami extra patrols screening residents and passing out critical supplies in the trouble zone. Officials in Miami confident they can keep zika contained. Once something starts, we nip it in the bud. Health officials are really encouragingeople who live near mosquitos anywhere, not just this neighborhood, to exercise caution and wear repellant. Cecelia. Eva, thank you. I want to bring in ABC's chief medical editor Dr. Richard Besser from Brazil, the center of the outbreak. Tonight you heard it, England saying pregnant women should not travel to Florida but the CDC not issuing the same warning. Is that a mistake? I have to say if these cases had occurred were the first cases in the caribbean country or Latin America they would issue that advisory but what they're saying is four cases that occurred in early July and no transmission since then, but I have to say if you're a pregnant woman and can avoid that part of Miami, that's not a bad idea and if you're pregnant and live there, you want to make sure you're using repellant all the time. We want to turn to San Diego.
