乐动体育登录Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by having venom sprayed into the eyes by certain species of snakes that have the ability to spit venom as a defence measure.
乐动体育登录Snake antivenoms are effective treatments to prevent or reverse most of the harmful effects of snakebite envenoming and are included in the WHO list of essential medicines. Most deaths and serious consequences from snake bites are entirely preventable by making safe and effective antivenoms more widely available and accessible, and raising awareness on primary prevention among communities and health workers.
- Immediately move away from the area where the bite occurred.
- Remove anything tight from around the bitten part of the body to avoid harm if swelling occurs.
- Reassure the victim, as most venomous snake bites do not cause immediate death.
- Immobilize the person completely and transport the person to a health facility as soon as possible
- Applying pressure at the bite site with a pressure pad may be suitable in some cases.
- Avoid traditional first aid methods or herbal medicines.
- Paracetamol may be given for local pain (which can be severe).
- Vomiting may occur, so place the person on their left side in the recovery position.
Inadequate past efforts to control snakebite envenoming has produced fragmented, inaccurate epidemiological data. Many victims do not attend health centres or hospitals and instead rely on traditional treatments. However, available data show 4.5–5.4 million people get bitten by snakes annually. Of this, 1.8–2.7 million develop clinical illness and 81,000 to 138,000 die from complications.
High-risk groups include rural agricultural workers, herders, fishermen, hunters, working children, people living in poorly constructed houses, and those with limited access to education and healthcare.
Morbidity and mortality occur most frequently among young people and children suffer higher case fatality. Furthermore, women experience increased barriers to accessing medical care in some cultures and pregnant women are extremely vulnerable.
In India alone, an estimated 2.8 million people are bitten by snakes, with almost 47 000 fatal cases. In Bangladesh, an estimated 589 919 cases occur each year, resulting in 6041 deaths. In Sub-Saharan Africa, up to a million people are bitten each year, with an estimated 7000–20 000 deaths. An ongoing crisis restricting access to safe, effective antivenom treatment in many regions, and particularly Sub-Saharan Africa, is one factor that contributes to the predisposition for seeking help through traditional medicine.
