Aedes aegypti. Know it and squish it!
There are over 3,000 species of mosquitoes. A fact I think proves there’s no benevolent deity.
This post is a run down of the basic info on the common mosquito born diseases in Brazil: dengue, zika, chikungunya, and yellow fever. It’s essential information if you’re visiting.
Because the mosquitoes are winning.
Last year in the wake of zika and the microcephaly epidemic in Brazil, the federal government mobilized troops to patrol for standing water basically declaring war against mosquitoes. The yellow fever outbreak this year is evidence of how well that went in the long term.
So here’s everything you didn’t want to need to know about mosquito born illnesses in Brazil.
DENGUE: Let’s start with dengue because it kills the most people every year. I know zika is the Kim Kardashian of the bunch, hogging all the media attention, but dengue is most likely to put you in the hospital. There were roughly 1.5 million registered cases of dengue in Brazil last year and of those 629 died. The severity depends on which of the four strains of the virus you get. The worst causes hemorrhaging, but most people just get incapacitating joint pain and high fever.
Dengue is usually transmitted through the bite of an infected mosquito, but it can be passed from mother to fetus. The disease is asymptomatic in 40-80% of cases. The incubation ranges from 3 to 14 days.
Symptoms
- Sudden high fever
- Severe headache
- Severe joint pain
- Moderate joint pain
- Severe pain behind the eyes (basically your body will hurt a lot)
- A skin rash that appears post fever
- Fatigue
- Nausea
- Itching
The Severe Case Symptoms (everything above plus…)
- Bleeding from the nose and gums
- Abdominal pain
- Vomiting
- Hypotension
- Dizziness
- Breathing difficulty
In rare cases, sometimes after a second infection, a person can develop dengue hemorrhagic fever which leads to shock and death in 24 hours. Yeah, dengue totally sucks.
There’s no vaccine. There’s no drug treatment. The only thing to do with dengue is treat the symptoms and be sure not use any aspirin because it increases the risk of hemorrhaging.

ZIKA: If you’ve been to Brazil in the last year and sneezed, you might have had zika. Or maybe you didn’t sneeze. You still might have had zika. Most cases are asymptomatic, about 80%.
Of the most common mosquito borne diseases, zika results in the fewest hospital cases. In 2016 there were 214,193 cases of Zika in Brazil and 3 deaths. The global panic over zika is because of it’s link to microcephaly, a condition that babies develop in utero which prevents the brain and skull from developing normally.
And let’s be clear. There IS scientific consensus that the zika virus is one of the causes of microcephaly. I believe in the CDC, WHO, and peer reviewed scientific journals. Conspiracy theorists can save themselves time and not bother commenting about genetically altered mosquitos. I will just delete them.
The fact the disease is asymptomatic in the majority of cases makes it particularly scary for women who are or may become pregnant. It’s possible to have zika and never know until the baby develops complications. Even if you develop symptoms, they’re usually mild.
Symptoms
- low grade fever
- headache
- skin rash starting on the face and spreading over the body
- red eyes
- itching
- fatigue
- sore joints
Less Common Symptoms
- Muscle pain
- Swelling
- Sore throat
- Vomiting or diarrhea
- Swelling
So now pregnant women all over Brazil can worry that their swollen legs and exhaustion is actually zika. Because there wasn’t enough for expectant parents to worry about. Fucking mosquitos.
There’s no vaccine.
CHIKUNGUNYA: Unlike zika and dengue, if you get chikungunya, you’ll know. 70% of cases develop symptoms. At least you don’t have to wonder whether or not you need a doctor.
Last year there were 265,554 cases of chikungunya resulting in 159 deaths, so worse than zika but not as prevalent as dengue.
Symptoms
- Sudden onset of high fever
- Severe joint pain mostly in feet, ankles, hands, wrists
About the joint pain, almost every case has it and in rare cases it becomes chronic.
Less Common Symptoms
- Intense back pain
- Headache
- Muscle pain
- Vomiting
- Conjunctivitis
- Fatigue
- Photophobia
- Sore throat
Basically everything hurts like hell.
Like the others, there’s no vaccine for chikungunya and no treatment beyond treating the symptoms.

YELLOW FEVER: The CDC’s website has a map of areas where yellow fever vaccines are recommended. The risk area for Brazil extends just up to the border of our state. So far this year 31 people have died from yellow fever in Esparto Santo. Dear CDC, you need to update your map.
Yellow fever is typically passed via an infected monkey to mosquito to human, so areas without dense forests were considered safe. The incubation period is 3 to 6 days but most cases are asymptomatic.
Symptoms
- Sudden high fever
- Severe headache
- Back pain
- Muscle pain
- Nausea & vomiting
- Fatigue
- Weakness
After a brief remission, 15% of cases will develop a severe form of the disease.
Symptoms of Severe Form
- High fever
- Jaundice (hence the name)
- Bleeding
- Shock
- Organ Failure
Of cases that turn severe 20-50% die.

But good news! There’s a vaccine! Two doses taken ten years apart provide lifetime immunity. Yay science! If you’re thinking about visiting Brazil this year, double check to see if your hotel is located within one of the new expanded risk area. Be sure to use a Brazilian site. Remember, the CDC’s map is out of date.
Vaccines are being developed for the other three. Several companies will have zika vaccines ready for clinical trials by the end of the year. Late stage clinical trials of dengue vaccines are already underway, and researchers have reported success with initial clinical trials for chikungunya vaccines. Unfortunately, we’re still years away from these vaccines being available to the public.
In the meantime, don’t cancel your vacation. Just be prepared. Get a yellow fever vaccine. Pack repellent. Sleep with your windows closed and fan on. And for god’s sake, if you see a mosquito, kill it!






Alright, now that we’ve covered 


13. Walk Along Copacabana Pretty self explanatory. The rules for beach going apply. Wear your shorts, tshirt and flip flops, bringing a little cash tucked away. Work out attire is fine too. The sidewalk will be full of people jogging and riding bikes. Grab a coconut to drink and stop and watch a game of footvolley. It’s volleyball played with your feet and it’s awesome.
15. Juice Crawl A staple of Rio is restaurants and kiosks specializing in fruit juice. The variety of fruit available to be freshly squeezed is astonishing and I can promise, no matter how hard you try, you will not be able to try juice from every fruit on the menu. My cousin made the most valiant effort I’ve ever seen, and even after consuming 2.5 liters of liquid during a walk from Leblon to Ipanema, she’d not tasted a quarter of the fruits on the menus.

18. Churrasco If you eat beef, you need to do so while in Brazil. Find a churrasco. Just type “churrasco Rio de Janeiro” into Google. They’ll probably be one within two blocks of wherever you’re standing. Brazilian know how to cook meat and they cook every part of the cow. Go for lunch and then plan on laying down for the rest of the day.
19. Watch Some Capoeira I’m sure there will be groups playing capoeira in the parks and beaches during the Olympics. With the exception of açaí, I don’t think there is a more uniquely Brazilian export. Capoeira is a Brazilian martial practiced to music and dance. I wrote a post explaining the

Last week my family and I were waiting in the citizens service area of the US Consulate in Rio de Janeiro, and I overhead a young man pouring out a pretty tragic story to the consulate staff standing opposite the bullet proof glass. He’d been robbed and had lost every single form of id, all his credit cards, and all his cash. He was left with no proof of identity whatsoever.
Because I have been a recently arrived foreigner in Rio without a word of Portuguese other than Obrigada and with the Rio Olympics opening in less than week, I’ve written down some tips to help visitors
This is the most depressing list of travel advice. I realize that. But before angry Cariocas start posting in the comment stream about the foreigner who doesn’t appreciate their magnificent city, I’m going to do a second post on all the great experiences in Rio. Now that everyone knows how to stay safe, I can recommend awesome things to do with the free time not being used up with emergency trips to the consulate or hospital. Come back on Wednesday for 
At the summer games this year in Rio de Janeiro, fans of 41 different sports will have a chance to watch competition between the best athletes in their sport. The world’s best judokas, golfers, divers, bmx cyclists, track cyclists, mountain cyclists (I had no idea there were so many different ways to cycle), trampoline jumpers, and fencers will be here in Brazil competing for gold. To be completely honest, I’m not sure what the modern pentathloners will be doing exactly, but I’m sure it’s something that I cannot.
Portuguese and later Brazilian officials were so frightened by capoeira they outlawed any and everything related to the game. People were arrested for playing capoeira instruments, wearing the colored belts and white pants, or just whistling a capoeira song. Finally, in the 1930’s Mestre Bimba from Salvador convinced the government that capoeira was both an important cultural legacy for Brazil and (because governments respond well to financial incentives) a tourist draw. In 1937, he was allowed to open the first public and officially sanctioned capoeira school in Brazil.
While the styles vary in speed and types of movement, both keep the same format and traditions for practicing. Capoeira is always played inside a circle of musicians, singers, other players, and spectators. The music of capoeira is performed on five instruments: berimbau, pandeiro, atabaque, agogô, and reco-reco. The musicians and singer perform continuously as players tag in and out of the circle. One more important fact! Players never actually strike each other while playing. They feint and dodge and kick, but they never land a blow. That’s why the verb “play” is used for capoeira. They’re playing, not fighting.


There’s so much bad news coming out of Brazil lately. The economy is still in tatters. The president is impeached. The interim president is according to most sources a mysogynist, corrupt pig. (And those are the nice names people are using for him.) Any waterbased Olympic events will require the athletes to wear hazmat suits. Zika.







I’m currently obsessed with an idea for a historical fiction novel and have spent the last week devouring books on colonial Brazil. (I know you’re jealous.) It’s been fascinating reading actually because it’s all entirely new history for me. It wasn’t until World History in high school that I even knew humans existed outside of Europe, and by “Europe” I mean Italy, France, and Britain with a brief stop in Germany for the Reformation. Any ideas I have about Portugal or South America I learned from Columbus Day themed picture books and Disney’s Emperor’s New Groove.

Last Saturday, the whole Barineau-Mauricio clan (all three of us) seized the day early (like 10ish) and headed to the beach. It was the kind of day that gets recorded and replayed in every tourist advertisement for the next decade. The temperature was perfect, warm enough to sit comfortably in a bathing suit but not oppressively hot. There was a steady breeze that my husband and daughter exploited for kite flying. It was a perfect beach day.
