Travel Diseases For 2022 

Vaccine-preventable disease outbreaks are disrupting international travel, says the U.S. CDC and World Health Organization (WHO). As of June 22, 2022, the CDC publishes vaccination-specific Travel Advisories and digital maps indicating current disease outbreaks in various countries. And the ECDC's recent vaccine-preventable disease update was issued on June 3, 2022.

Travel Diseases

Chikungunya: Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It is caused by the chikungunya virus (CHIKV). A CHIKV infection causes fever and severe joint pain. Other symptoms include muscle pain, joint swelling, headache, nausea, fatigue, and rash.

Cholera: Cholera is an acute diarrhoeal disease that can kill within hours if left untreated. Providing safe water and sanitation is critical to preventing and controlling the transmission of cholera and other waterborne diseases.

Dengue: Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes. The primary vectors that transmit the disease are Aedes aegypti mosquitoes and, to a lesser extent, Ae. albopictus. There are four DENV serotypes, and it is possible to be infected four times. Severe dengue is a leading cause of serious illness and death in some Asian and Latin American countries. Therefore, it requires management by medical professionals.

Ebola: Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, is a rare but severe, often fatal illness in humans. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The average EVD case fatality rate is around 50%. However, case fatality rates have varied from 25% to 90% in past outbreaks.

Malaria: Malaria is a life-threatening disease caused by parasites transmitted to people through the bites of infected female Anopheles mosquitoes. It is preventable and curable.

Measles: Measles is a highly contagious, serious disease caused by a virus. Even though a safe and cost-effective vaccine is available, in 2018, there were more than 140 000 measles deaths globally, mostly among children under five.

Monkeypox: Monkeypox is caused by the monkeypox virus, a member of the Orthopoxvirus genus in the family Poxviridae. Monkeypox is transmitted to humans through close contact with an infected person or animal or with material contaminated with the virus.

Polio: Polio is a highly infectious disease caused by a virus. It invades the nervous system and can cause total paralysis in hours. Polio mainly affects children under five years of age.

Rabies: Rabies is a vaccine-preventable viral disease in more than 150 countries and territories.

Tick-Borne Encephalitis: Tick-borne encephalitis virus is a member of the family Flaviviridae. Most infections with the virus result from infected ticks, which often remain firmly attached to the skin for days.

Typhoid: Typhoid fever is a life-threatening infection caused by the bacterium Salmonella Typhi. It is usually spread through contaminated food or water. Two vaccines have been used for many years to prevent typhoid. However, a new typhoid conjugate vaccine with longer-lasting immunity was prequalified by WHO in December 2017.

Tuberculosis: Tuberculosis is a potentially serious infectious disease that mainly affects the lungs. The bacteria that cause tuberculosis are spread from person to person through tiny droplets released into the air via coughs and sneezes.

Yellow Fever: Yellow fever is an acute viral hemorrhagic disease transmitted by infected mosquitoes. The "yellow" in the name refers to jaundice that affects some patients. Symptoms of yellow fever include fever, headache, jaundice, muscle pain, nausea, vomiting, and fatigue. A small proportion of patients who contract the virus develop severe symptoms, and approximately half of those die within 7 to 10 days.
