Spider bites are also called arachnidism and are caused by the biting of a spider. Most spider bites are not significant however bites from certain species can cause neural damage as they contain neurotoxic venom.

One such species of spider is the widow spider. General symptoms of such bites are muscle ache, sweating, or pain at the site of the bite.

What is Snake Bites?

WHO categorizes snake bites as Neglected Tropical Disease. According to WHO snake bites are a public health issue generally prevalent in the tropical and subtropical regions of the world.

According to the estimates almost 4.5 million to 5.4 million are affected by this health issue each year.

The symptoms are mild in case of a dry bite. Most snake bites are not deadly but if the venom is neurotoxic and treatment is delayed then it may cause serious tissue damage and in some cases death.

To prevent severe effects one should keep a few things in mind.

General treatment should be avoided and one must rush to a hospital. The person should be calmed down and any tight cloth or jewelry around the affected area must be removed to prevent swelling.

One must not attempt to suck out the venom as it could be deadly and cutting the affected area must be prevented.

In severe cases it may lead to kidney failure, tissue death, bleeding, etc. so, care must be taken and one must try to identify the type of snake that caused the injury.

Finding the type of snake is very helpful in administering antivenom as it is specific to the specific snake. In the case of an unidentified agent, antivenom can be administered based on a prevalent snake in the area.

What is Spider Bites?

Spider bites are not so severe in most cases. However, it can cause serious damage if the spider is venomous. The spider bite may lead to severe pain and necrotic skin around the area of the bite. It happens in rare cases.

For a bite to be significantly dangerous a particular dose of venom is required which is not the case with spider bites. Spiders generally use their venom to kill their prey and their fangs are very small so in most cases, it causes little to no harm.

It can be treated with anti-inflammatory drugs coupled with antihistamines for itching.

In very severe cases antivenom should be used. It must be considered if the venom is neurotoxic in nature. The type of spider must be known as it helps to prevent misdiagnosis. To prevent spider bites several cares can be taken.

One can keep clutter around clean and pesticide is highly recommended.

Several conditions arise from spider bites. In one such condition called tarantism, the person affected dances wildly. Necrosis is also one of the conditions reported which is attributed to the bites of recluse spiders.

In most cases, spider bites are misdiagnosed due to a lack of knowledge and experiments.
