But it is travel-related,” Fauci said during an appearance on ABC’s _This Week._ “The concern is that we will have local transmission,” he added. “In other words, people who get infected in the United States, get bitten by a mosquito, but who have never left the continental United States. We fully expect that that will happen as we get to the more robust mosquito season in the next month or so.” “We need to make sure that those local outbreaks don’t become sustained and don’t become disseminated,” Fauci said. “That’s the reason why we need to have a very, very forceful preparation right now before that happens.” There are more than 500 travel-related cases of the Zika virus in the U.S., according to [new figures](http://www.cdc.gov/zika/) from the Centers for Disease Control and Prevention. None of them were locally transmitted by mosquitoes. President Obama has asked Congress to [allocate $1.9 billion](http://time.com/4343317/president-obama-zika-funding-congress-us/) in emergency funding to combat the spread of the virus. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4345249/zika-virus-us-forceful-preparation/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4345249/zika-virus-us-forceful-preparation/"},"headline":"Zika Virus Likely to Spread in U.S. 'in the Next Month or So,' Official Says","datePublished":"2016-05-23T19:30:18.000Z","dateModified":"2026-03-31T09:40:35.972Z","description":"There are more than 500 cases of the Zika virus in the U.S.","url":"https://time.com/4345249/zika-virus-us-forceful-preparation/","keywords":["Zika"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blte8631db003f482b9/69889474cf40a84459c43589/zika-usa-preparation.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Melissa Chan","jobTitle":null,"url":"https://time.com/author/melissa-chan/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blte8631db003f482b9/69889474cf40a84459c43589/zika-usa-preparation.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Health Workers Test And Spray For Mosquitos As Texas Prepares For Zika Virus","caption":"City environmental health specialists Gerardo Valdez (L), and Aaron Salazar transfer live mosquitos caught for testing in McAllen, Texas, on April 14, 2016.","creditText":"John Moore—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/zika/","name":"Zika"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4345249/zika-virus-us-forceful-preparation/","name":"Zika Virus Likely to Spread in U.S. 'in the Next Month or So,' Official Says"}}]}] ```
