Medical tourism is a fast trending industry which is flocked by millions of people every year. Medical tourists travel to receive cheap and quality treatment abroad. Patients who undergo treatment abroad usually opt for packages which include the operation, stay, pre-operation procedures and also the post-operative care.

Travelling to a new country might lead to some problems for the patient as they might face communication barriers, infections, etc. Patients are more likely to catch certain diseases and infections in the foreign country since they are in the state of recovery after their procedure. The outbreak of the disease may happen either preoperatively or postoperatively as the patient’s body is weak and less immune to the new environment that s/he is in.

Following are the diseases a patient needs to be aware about, when travelling abroad for medical treatment.

Traveler’s Diarrhea

Traveler’s Diarrhea is a stomach and intestinal infection. It can also be termed as digestive disorder that causes loose stools and abdominal cramps. Contaminated food and water are the culprits behind the spread of this disease. The possible symptoms include nausea, vomiting, bloating, cramps, loss of appetite etc. Developing countries are high-risk destinations where travelers are likely to get traveler’s diarrhea. Australia, Europe, Israel, Japan, Mexico, South Africa, etc. are the zones where one might catch this disease.

The risk of this disease can be minimised by avoiding raw fruits and vegetables, tap water and dairy products in the foreign country. A person suffering from this disease can take ORS solutions which replaces the loss of salts from the body.


This disease is spread by female mosquitoes carrying a parasite called plasmodium. The mosquito bite induces the parasites into the person’s blood which travels to the liver where they mature and reproduce. The main symptoms of this disease are fever, chills, headaches, and vomiting.

In 2012 , there were about 207 million malaria cases and an estimated 6,27,000 deaths, mostly in the regions of Caribbean, Latin America, Asia, and especially tropical regions in Africa.

Patients are advised to carry mosquito repellent creams to keep themselves from this disease and wear long clothing. Also, care should be taken to sleep in an air-conditioned room to avoid contact with mosquitoes. The treatment for malaria includes a combination of antimalarial medications which includes an artemisinin.
