Pneumonia isn’t just the cold.

You aren’t more likely to catch the virus if you go outside during the winter without a coat.

People 65 years or older aren’t the only ones who can catch pneumonia.

The myths about pneumonia have been debunked, but one fact is important. Pneumonia sends about one million Americans to the hospital and 50,000 deaths every year. Here’s what you do need to know about the deadly virus:

What is pneumonia?

The smallpox vaccine is credited to English doctor Edward Jenner.

His reputation is well-earned, as he studied the disease and ways to prevent it for decades.

Jenner first used his vaccine by exposing an eight-year-old boy to a cowpox-infected needle. Although the boy suffered some symptoms from the cowpox, he was immune to smallpox.

But, a man tried this method years earlier despite spending his life trying to eradicate something far different: witches.

Cotton Mather was a popular minister and scholar in late 17th century Boston. The son of Increase Mather, another prominent minister, the duo were well-known advocates for the Salem witch trials.

Brazil is an exciting travel destination with much to offer to any type of traveler. The city is the heart of Brazilian culture and houses some of the most amazing sights and sounds in the country.

Rio’s immense terrain offers endless choices to make your own adventure. Visiting the rainforest allows for hiking, kayaking and rock climbing that can’t be surpassed by any other place in the world. Staying along Rio’s coastline gives access to endless surf spots and the bustling communities. But, you’ll need to start preparing early if you’d like to take advantage of the city’s sprawling opportunities.

Which Vaccines Do I Need For A Trip to Rio de Janeiro?

The various climates and regions of Brazil provide travel health challenges. Despite being the fifth largest country in the world and one of the largest economies, Brazil is still developing. Do not forget this fact. Many areas lack proper sanitation, and some diseases not seen in the United States are present.

Luckily, many of these infections are preventable through vaccination. The Centers for Disease Control and Prevention and World Health Organization recommend travelers receive the following vaccines:

• Routine Vaccinations– Before you leave, make sure you are up-to-date on your routine vaccinations such as the MMR (measles, mumps and rubella) vaccine and TDaP (tetanus, diphtheria and pertussis) as some of these diseases can be found in developing nations.
• Yellow Fever– This mosquito-borne disease is prevalent in many parts of Brazil including Minas Gerais, just north of Rio de Janeiro. The CDC recommends travelers to affected regions receive a yellow fever vaccine. If you are planning to visit other countries in South America before traveling to Brazil, the vaccine may be required for entry into Brazil.
• Typhoid– The vaccine is recommended for most travelers to Brazil. As a foodborne disease, typhoid is prevalent in many developing countries like Brazil. Take proper precautions to avoid contaminated food. ‘Adventurous eating’ could lead to typhoid infection, especially if you have not been vaccinated.
• Hepatitis A– This is another foodborne disease. Hepatitis A vaccination is recommended for all travelers to Brazil.
• Hepatitis B– Most travelers should consider this vaccine. It is recommended for those who may be exposed to bodily fluids while in Brazil. This includes sexual contact, getting tattoos or even getting a medical procedure.
• Rabies– While not always necessary, this vaccine may be recommended based on your itinerary. Spread through animal bites, rabies can be a deadly disease, especially if it goes untreated.

Each individual’s itinerary may change what vaccines are recommended or required. Consult with a travel health specialist to learn more.

Which Mosquito-borne Diseases Are Present in Brazil?

The jungle and rural environments are hotbeds for mosquito-borne disease activity. But, these diseases have also begun to enter some urban environments such as Rio de Janeiro.

• Malaria– A parasite spread through mosquito bites, malaria is common in some regions of Brazil. Speak with a travel health specialist about whether you will need antimalarial medication for your trip.
• Dengue– There is an increased risk of infection in urban and residential areas. This mosquito-borne disease is rarely deadly, but it can ruin a trip. There is no vaccine against dengue, just preventative measures like mosquito repellents and netting.

Zika and Rio de Janeiro

The mosquito-borne virus Zika has been found in Brazil. The virus is known to cause mild to moderate symptoms in adults, like dengue does. But, it has been found to cause microcephaly (a birth defect causing shrinking of the head) in the fetus of infected mothers.

The CDC recommends women who are pregnant or may become pregnant consider not traveling to Rio de Janeiro.

Be sure to take proper precautions against mosquitoes while in Rio. This includes using mosquito netting and repellents as well as wearing proper clothing.

Is Traveler’s Diarrhea a Risk In Brazil?

Traveler’s diarrhea is a risk throughout South America, perhaps even more so in Brazil. A recent study commissioned by the Associated Press found water in Brazil is highly contaminated with various viral and bacterial diseases. One expert went even said, “If we saw these levels here in the United States on beaches, officials would likely close [them].”

It is not uncommon to fall ill while in Rio without proper medical preparation. We recommend that you preemptively take antibiotics or other medications to avoid illness.

It is extremely important to protect yourself while in Rio. Finding safe foods to eat and beverages to drink can become difficult while traveling, and this is especially when you are ‘on-the-go’. This could lead to you or a member of your group being exposed to the agents that cause traveler’s diarrhea.

Traveler’s diarrhea can be caused by a variety of factors. There is no ‘traveler’s diarrhea’-specific vaccine. But, typhoid and hepatitis A vaccinations can help avoid two types of infection.

Bring a traveler’s diarrhea kit, with products like DiaResQ, to help protect yourself from missing any of those adventure opportunities.

Other preventative advice includes:

• Do not drink tap water unless it has been boiled or otherwise treated.
• Do not drink unbottled beverages or drinks with ice
• Do not eat raw or undercooked meat or fish; this includes ceviche

Will I Be Safe During My Trip to Rio de Janeiro?

According to the U.S. State Department, crime remains high in many of Brazil’s urban areas. Street crime is a problem for visitors and locals, especially in Rio. The State Department also gives the following advice:

• Be extra watchful on buses or in other public areas. Pickpocketing and other forms of theft are common in these places.
• Do not wear jewelry or expensive watches in public. Anything that could attract attention may also attract crime.
• DO NOT carry your passport with you as it could be stolen. Leave your passport in a hotel safe and carry a photocopy or a passport card with you at all times.
• If you are are robbed, do not attempt to resist or fight. Hand over the belongings as this is the safer decision
• The State Department also recommends avoiding ‘favelas’ as they are sites of increased crime and violence

Do I Need A Visa To Travel To Rio de Janeiro?

Brazil usually requires a visa for US citizens to enter the country. Although Brazil can sometimes offer travel without a visa, this is only during special events hosted within the country, such as the FIFA World Cup or the Olympics. Currently, you will need a visa for travel.
