Common Travel Illnesses

What is travel Illness?

Most of us love to travel because it offers the possibility of exploration, adventure, and cultural enrichment. But it’s also a journey where we might collide with Common travel Illnesses, an unanticipated and unwelcome companion that we all are scared of. Travelers and other people who consume stale food or water can get traveler’s illness. It is a brief but uncomfortable gastrointestinal infection that frequently results in loose stools and cramps in the abdomen. The majority of the time, bacteria are to be blamed. International travelers are most at risk. When visiting nations with less stringent sanitation regulations than their own. Along with these ailments, people may also suffer from migraines, body aches, jet lag, and other ailments that we will cover below.

Who is affected by travel illnesses?

Anyone and everyone who is traveling can get sick. However, it is more common to contract it when traveling abroad because you are more likely to come into contact with pathogens that may be less frequently transmitted at home. Generally, people who are not very used to traveling and its exertion get sick easily. Elderly and toddlers are more prone to get sick. If you have any pre-existing illnesses, make sure to be in touch with your doctor at every point of time.

Types of Travel Illness

  1. Malaria

In tropical and subtropical climates, mosquitoes transmit the parasitic disease malaria. High fever, chills, and flu-like symptoms are the results. Additionally, it can result in anemia, a condition where the body lacks red blood cells and feels weak or exhausted.

When a mosquito that is carrying the malaria parasite bites a person, the parasite enters the bloodstream and spreads the disease. After that, the parasite moves on to the liver, where it grows. Once red blood cells are infected by these parasites, they burst and spread to other red blood cells throughout the body.

10 days to 4 weeks after a bite from an infected mosquito, symptoms typically start to reflect. They consist of chills and sweats, muscle aches, nausea, vomiting, and diarrhea, as well as recurrent fevers that can reach 106 degrees. Jaundice, a skin-yellowing condition that can indicate liver dysfunction or severe red blood cell destruction, may also be brought on by severe infection.

Malaria can result in more severe issues, such as harm to the heart, lungs, kidneys, or brain. Fever and the cycle of red blood cell deterioration can be fatal if left untreated. Therefore, this needs quick diagnosis and treatment.

  1. Dengue

One of the four types of dengue viruses is what causes the disease, which is contracted by mosquito bites and spread to people. It can have fatal consequences in severe cases and cause excruciating flu-like symptoms. There is no treatment or vaccine to prevent dengue fever.

In areas where dengue is present, all travelers face risk. During the day, particularly at sunrise and sunset, the risk is greater.

Travelers who stay only a short time in air-conditioned lodgings with well-kept grounds and engage in outdoor activities during off-peak biting seasons run a lower risk.

A person who survives one of the four varieties of dengue will have lifetime immunity to that specific variety but not to the others. Through the bite of an infected mosquito, especially the Aedes aegypti and Aedes albopictus species, dengue fever is transmitted to humans.

What signs are present?

Three to fourteen days after being bitten by an infected mosquito, the symptoms will typically start to show up. Typical flu-like symptoms include high fever, excruciating headache, eye pain, joint and muscle pain, nausea, vomiting, and rash.

Is dengue fever treatable?

Dengue fever has no specific treatment, but medical attention can aid in recovery and the management of symptoms.

Which parts of the world are most affected by dengue?

Although dengue fever can be found anywhere in the world, it mostly affects tropical and subtropical regions. Africa, Central and South America, the Caribbean, the Eastern Mediterranean, South and Southeast Asia, and Oceania all have large populations of it. Over 40% of people worldwide, according to the World Health Organization (WHO), reside in areas where dengue viruses can spread.

  1. Typhoid Fever

The bacterium Salmonella Typhi is the source of the potentially fatal disease typhoid fever. Consuming food, water, or feces that have been contaminated with these bacteria can spread it. Typhoid fever patients have the bacteria in their blood and intestines.

Following ingestion, the Salmonella Typhi bacteria multiply in the digestive system before spreading to the bloodstream. Fever and malaise are the body’s response; headaches and abdominal pain can also happen.

Typhoid fever can be fatal if untreated. Small, red-colored spots on the skin of the chest and abdomen may appear in addition to the fever, which starts 7 to 14 days after ingesting the bacteria and peaks at 103 to 104 degrees.

Typhoid fever affects people all over the world, but it is most common in developing countries with subpar sanitation, where handwashing is less common, and water is more likely to be tainted with sewage.

  1. Yellow fever

The flavivirus that causes yellow fever is spread by the bite of an infected mosquito. Its name derives from the jaundice, or yellowing of the skin and eyes, which happens when the virus attacks the liver. An anti-yellow fever vaccine is available.

Where am I at risk?

Numerous variables, such as your travel destination, the season, the duration of your trip, and the kinds of activities you engage in, can affect your risk.

The majority of visitors run a low risk. Still, those who visit remote or dangerous areas, stay for an extended period, or engage in outdoor activities may run a higher risk.

How does it spread?

Through the bite of infected mosquitoes, primarily the Aedes species in Africa and the Haemagogus species in South America, yellow fever is transmitted.

Yellow fever-carrying mosquitoes typically bite during the day, especially at sunrise and sunset.

What signs are present?

It may take 3 to 6 days for symptoms to manifest. Typical initial signs and symptoms include a sudden onset of fever, chills, headache, joint and muscle pain, loss of appetite, abdominal pain, back pain, nausea, and vomiting, as well as exhaustion, weakness, and dehydration. After this stage, the majority of patients recover.

When the condition is severe, it can cause shock, internal bleeding, jaundice (a condition in which the skin and whites of the eyes turn yellow), and organ failure. 15% of patients experience this, and 50% of them pass away within 10 to 14 days.

Is yellow fever curable?

Yellow fever does not have a specific treatment; rather, supportive care is used to lessen symptoms.

Where does yellow fever pose a risk?

In many tropical regions of Africa and South America, yellow fever is endemic, or always present.

When infected people move from rural or jungle areas into densely populated areas, the disease can spread to urban areas where mosquitoes bite infected people and then bite uninfected people, causing yellow fever.

Common Travel Illnesses

  1. What is traveler’s diarrhea?

The most typical illness that affects travelers is traveler’s diarrhea. It is quickly spread from person to person or when drinking or eating contaminated food. Traveler’s diarrhea can be brought on by a wide range of bacteria, including E. coli, Salmonella, Shigella, and Campylobacter, as well as parasites like Giardia, Cryptosporidium, and Cyclospora, and viruses like rotavirus and norovirus.

Where am I at risk?

When visiting locations with subpar standards of hygiene and sanitation and/or eating in establishments with subpar food handling practices, travelers are more at risk.

More vulnerable groups include young children, the elderly, and those who already have health issues.

How does it spread?

Inadequate personal hygiene makes it easy for travelers’ diarrhea to spread through contaminated food, water, or person-to-person contact.

What signs are present?

The bacteria, parasite, or virus that has caused the illness will determine the symptoms.

They typically include fever, nausea, vomiting, bloating, abdominal cramps, and the urgent need to go to the bathroom in addition to diarrhea.

Without treatment, the symptoms usually disappear in a few days.

Traveler’s diarrhea can cause severe and extremely rare cases of dehydration and even death. Children, the elderly, and those with chronic illnesses or weakened immune systems should pay special attention to this.

Even if your other symptoms are not too severe, you should still see a doctor if you have blood in your stool.

Can you treat traveler’s diarrhea?

After a few days, the majority of symptoms disappear on their own. The most crucial treatment is to keep hydrated:

Take in a lot of liquids. Children, elderly individuals, and those who already have health issues should pay special attention to this. Use oral rehydration solutions in cases that are moderate to severe. Always use safe water to drink or to mix your oral hydration solutions (boiled, disinfected, or from a commercially sealed bottle).

Anti-motility medication may in some circumstances offer some symptom relief (regular and urgent need to use the restroom). You shouldn’t take this kind of medication if you have a fever or bloody diarrhea. It’s crucial to carefully adhere to both your doctor’s advice and the instructions on each medication. If you have moderate to severe diarrhea, your doctor may suggest using antibiotics to treat it.

Where are cases of traveler’s diarrhea a problem?

Travelers’ diarrhea is a risk that exists everywhere. Developing nations in Central and South America, Mexico, Africa, the Middle East, and Asia are among the high-risk locations. Eastern Europe and some Caribbean islands present a moderate risk. In Australia, New Zealand, Japan, Northern and Western Europe, the United States, and Canada, the risk is lower.

Hepatitis A

A liver virus called hepatitis A is frequently acquired while traveling abroad by consuming tainted food or beverages. Additionally, it might be contracted by being near an infected person.

Viral particles travel from the gut to the liver, where they reproduce. The liver can suffer severe damage when infected. Liver disease could result from a persistent infection. The virus is eliminated by bile and leaves the body through the feces, which continue to be its main vector. The virus can also spread through close contact with the blood of an infected person.

What signs are present?

The symptoms of hepatitis A can range from minor to serious. These consist of:

  • Nausea
  • Vomiting
  • Orange-colored stool containing bilirubin.
  • Dark feces
  • Pain in the area of the abdomen where the liver is located.
  • Fever
  • Fatigue
  • Itchiness
  • Jaundice (orange-yellow skin tone and eyes with a yellow tint)

The incubation period of the virus ranges from 14 to 28 days on average. Many people who get the infection don’t exhibit any symptoms. 2–7 weeks after infection, symptoms start to appear in symptomatic people. Although most people get better in two months, some people may continue to have symptoms for up to six months. Jaundice only occurs in 10% of people with hepatitis A.

How can it be treated?

You can consider getting vaccines. It is generally, immune to you for 17 years. You can see yourself getting better from two doses given six months apart. If quick travel is necessary, the second dose can be spread out since one dose typically protects for more than a year. Only people under the age of 40 are advised to get vaccines because their effectiveness is reduced in older people.

Other than lots of rest and rehydration, there is no cure for hepatitis A. To ensure that there are no complications related to liver disease or failure, it is a good idea to see a doctor once symptoms start to appear.

Travel Safety Measures

By keeping themselves clean and avoiding potential sources of contamination, travelers can prevent getting all of the above-mentioned diseases. Bottled water and properly cooked food can help lower the risk of acquiring viruses. For the best immunization and its duration, you can consult our doctor.
