Is the Zika virus in Uruguay?

It's a *South American* epidemic, right? Not so. South America is huge and diverse. Uruguay has had just one case of Zika virus, much less than the USA.

I was surprised by the panic around the Zika virus during a recent visit I made to the USA. After all, I live in South America, where according to the US media Zika is a huge epidemic.

So, the first thing you need to know if you are considering a trip to Uruguay is that locally, noone is concerned about Zika.

Let’s get a little perspective.

Zika is carried by the Aedes aegypti mosquito. Mosquitos thrive in warm climates, especially tropical climates.

South America is a huge continent made up of lots of different countries. Some of those countries to the north are tropical or have areas that are tropical* and have mosquitos all year round.

Other countries have temperate climates so during their winter the mosquitos die outUruguay falls into this latter group.

Is the Zika virus in Uruguay?

Uruguay has had just one case of Zika—ever. A local man who had been on holiday in Brazil contracted it and the case was reported in April this year. Since then there have been no other cases.

Compare this to the USA where there have been over 800 cases confirmed.

So should you be worried about Zika if you come to Uruguay?

If you are planning your trip between the time of writing and mid spring then you really have no need to worry. We are in winter and mosquitoes are inactive in winter. They reactivate when temperatures regularly reach 18 degrees, in say, October or November.

But even as summer approaches, you are in good hands. Historically Uruguay has a very good public health system and a population that embraces public health campaigns.

For instance, after being the only country in this part of South America to have never had a reported case of local dengue, in February there was a local outbreak. The Ministry of Health stepped in quickly to control spread. Within a month the outbreak was over, there had been just thirty cases and no deaths.

Besides, with air travel so prevalent nowadays you are just as likely to come into contact with Zika in Canada as in Montevideo.

So get informed about Zika

I would recommend you listen to this 30-minute interview on NPR’s Fresh Air with the author of a new book Zika: The Emerging Epidemic. Donald G McNeil Jr says in a nutshell that unless you are planning to get pregnant, or get your partner pregnant then you should not be concerned about Zika.

The interview also looks at the situation of visiting South America for the Olympics. It gives a nuanced perspective to combat the broad-brush semi-hysteria being whipped up about a supposedly “Zika-infested South America”.

(It seems absolutely exaggerated to me that due to an outbreak in an Argentinian city fourteen hours drive away from Buenos Aires, the CDC has placed the entire country on its Zika alert list (oh, unless you’re staying over 6.500 ft!). When mosquitoes are lucky to fly half a mile in their entire lifespan. Anyway.)

*Some countries are so huge they have a variety of climates. So northern Brazil is hot year-round whereas southern Brazil has cold winters, just like Uruguay.

  1. Hi are the mosquitoes bad in Montevideo ? We’re thinking of coming in October or November if we can get in the country .

    1. Hi Deborah, mosquitoes are not really much of a problem in Montevideo. Just a bit of repellent some evenings if you’re on grass or a repelling device when sleeping might be needed depending on how tasty you are to the critters. Where are you coming from? Best, Karen

  2. Hi there. I am 18 weeks pregnant and we are going to Jose Ignacio and La Pedrera in mid February. I want to make sure this information is still accurate and people in Uruguay who are pregnant aren’t actively scared of Zika? I will wear bug spray.

    1. Hi Amanda, noone is concerned about Zika, so no need to be concerned. Have a wonderful time! — Karen

  3. Is this information still correct? I booked flights to Uruguay and was planning to do Uruguay plus Buenos Aires and then a jot down to Tierra del Fuego. I stupidly only looked up Uruguay before booking flights and didn’t think to check about Zika when extending the itinerary to Argentina. My partner and I will start to try for a baby a few weeks before we’re meant to travel. Is it realistic that Buenos Aires, which is non-tropical and less than 100km from Zika-free Uruguay, or Usuaia/Tierra del Fuego, which is so far south that temperatures don’t get up past 10 degrees celcius are actually a huge risk? I wish I had done more research before buying plane tickets (it’s my first trip abroad in a while, I got ahead of myself), but given the situation where we can’t change the tickets without incurring ridiculous expense, is it better to just eat the cost, or would we be fine to go as planned and then just make sure we’re tested for Zika on our return?


    1. Hi Clare, I do not think you should be at all concerned. As I explain in the article this is a case of the US press lumping tens of extremely different countries into the same basket. I would say you are at more risk in the US than you are in Uruguay or Buenos Aires and Patagonia. All the best, Karen
