Summer vacation is coming, and students are going out one after another. However, pan Xingfei, director of the outpatient department of travel related infections in the Third Affiliated Hospital of Guangzhou Medical University, reminded that people who travel, especially those who go to tropical areas, should pay special attention to the prevention of the following three “travel diseases”. They can carry some commonly used drugs and be prepared.
Insect borne diseases
Pan Xingfei introduced that tropical and subtropical regions are the epidemic areas of insect borne infectious diseases. Common insect borne infectious diseases include: dengue fever, malaria, Japanese encephalitis, Zika, yellow fever, chikungunya fever, etc. transmitted by mosquitoes; African tick bite fever, Mediterranean spotted fever, tick borne encephalitis, etc. transmitted by ticks; tsutsugamushi disease transmitted by Chigger Mites, plague transmitted by fleas, sleeping sickness transmitted by tsetse flies, etc.
Symptoms: mainly “fever”. Different insect borne infectious diseases also have different manifestations: malaria may have intermittent fever, high fever after shivering and fever regression after sweating; some may have characteristic skin rashes, such as dengue fever may have needle like bleeding points, tsutsugamushi disease may have eschar; Japanese encephalitis may have neurological symptoms and disturbance of consciousness; yellow fever may have jaundice; some severe patients may have systemic complications, Even death.
Prevention: to prevent insect borne diseases, the most important thing is to prevent mosquito bites. You can use mosquito repellents such as DEET, or wear long sleeve clothes and trousers, use screen windows and screen doors in rooms, and hang mosquito nets when sleeping. If you enter the forest area, you can use insecticides such as Miemie Silin to treat clothes, shoes, socks, mosquito nets, sleeping bags, etc.
If you go to some areas with high risk of malaria infection in Africa, in addition to taking anti mosquito measures, you also need oral drugs, such as doxycycline, for preventive medication; if you go to some yellow fever endemic areas in Africa, you also need to provide yellow fever vaccination certificate when you enter.
Insect bite dermatitis
Some friends travel back to find itchy skin, and even a lot of rash, this is an infectious disease? Pan Xingfei explained that this kind of situation often belongs to insect bite dermatitis, also known as papular urticaria, which is mainly related to the bites of arthropods, such as mites. Due to the difference of insect species and body reactivity, it can cause different skin reactions at the bite site.
Symptoms: local redness and swelling, papules, wheezes or bruises, tingling, burning and itching. However, insect bite dermatitis is not an infectious disease and is not infectious.
Prevention and treatment: insect bite dermatitis should also pay attention to the prevention of mosquito bites, pay attention to personal and environmental hygiene, frequently change clothes, avoid drinking and eating irritating food. As soon as there are prodromal symptoms or wheal like damage should be timely medication, can reduce the attack. Oral drugs can choose chlorpheniramine, cetirizine, loratadine and other antihistamine drugs, external use can be smeared calamine lotion to reduce symptoms. Some symptoms are more serious may need to use hormone, if combined with bacterial infection also need to use antibiotics, it is recommended to go to the hospital.
The Third Affiliated Hospital of Guangzhou Medical University, Department of infection medicine, Dr. Xue Ting, said that travelers’ diarrhea, commonly known as “acclimatization”, is a kind of intestinal infectious disease, which is mainly caused by a variety of microorganisms, including viruses and bacteria. It occurs by drinking contaminated water or eating contaminated food. Infectious diarrhea can be mild or severe, severe may be life-threatening.
Caution: mild can take loperamide or bismuth subsalicylate treatment, severe to see a doctor as soon as possible.
Prevention: develop good hygiene habits, wash hands frequently with soap and water, use bottled water as drinking water and water for brushing teeth and gargling, pay attention to food hygiene, avoid drinking tap water, avoid eating washed food (such as salad), ice, non pasteurized milk, homemade sauces and sauces, undercooked seafood, fresh or undercooked meat, street vendors Food for sale, etc.
In addition to the above three types of common “travel diseases”, pan Xingfei also reminded that some accidental injuries, such as cuts, burns, stabs and other skin injuries, will inevitably occur during going out. In case of skin injury, clean and dry gauze and bandage can be used to bandage the wound, and even slight and uninfected wounds should be disinfected. In addition, when the body has wounds, avoid swimming in swimming pools, rivers and lakes, avoid exposing the wounds, and regularly disinfect the wounds and change dressings.
