But then a red lesion appears that becomes a blister. The appearance of the blister may be followed by fever, nausea, and a body rash. Blister may enlarge into a very painful ulceration. If shock occurs, take appropriate measures. Take the victim to the nearest hospital as soon as possible.
Medical evaluation is extremely important.
Surgery may be necessary to repair the ulcerated area. While there are about 45,000 snakebites a year in the United States, only about 7,000 of these injuries involve poisonous snakes, resulting in about 10 deaths annually, only one-fourth the number that die from bee stings. Poisonous snakes are found in every state except Maine and Alaska. Although not all bites from poisonous snakes result in the release of poison, once the skin is punctured by snake fangs you should assume that poison is present and act accordingly. It is urgent that a snakebite victim be taken to a hospital for antivenin serum as quickly as possible, certainly within 4 hours.
