Leeches are commonly found in moist and humid environments, such as forests and marshy areas, and are known for their ability to suck blood. They are often a concern for tourists visiting such areas, as their bites can cause discomfort and potential health issues. In Nepal, leeches are commonly found in the foothills of the Himalayas, particularly during the monsoon season from June to September. T
hey are attracted to body heat, movement, and carbon dioxide, and will often attach themselves to exposed skin, particularly around the ankles and feet. Although leeches do not transmit diseases, their bites can cause local irritation, itching, and sometimes a mild allergic reaction. If you are bitten by a leech, it is important to remove it promptly using a blunt object, such as a fingernail or credit card, to avoid squeezing or crushing the leech, as this can release more toxins into the wound. After removing the leech, clean the wound with soap and water and apply an antiseptic cream or ointment.
To prevent leech bites, wear long pants and sleeves, tuck your pants into your socks, and apply insect repellent containing DEET or picaridin to the exposed skin. Some natural remedies, such as applying salt, vinegar, or tobacco to the leech, are not recommended as they can aggravate the leech and increase the risk of infection.
Overall, while leeches may be a nuisance for tourists in Nepal, they are not a major health threat and can be easily avoided and treated.
