The great r numbers of Snakebite victim in Kenya take hours to days before they present in hospital and this increases the morbidity and mortality of those affected. [erepository.uonbi.ac.ke]
Two styles of presentation have been adopted. Certain topics are discussed in depth either because of their clinical importance or because recent data have become available concerning pathophysiology or treatment. [books.google.com]
This special vomeronasal organ detects pheromones and other chemical signals, and is used to determine what is present within the snake’s immediate environment. Poorer world without me The snake is a biological controller. [sanbi.org]
They don't present themselves, generally, until 24 - 48 hours following the bite. Bleeding from mucous membranes is usually the first symptom to show up. This is followed by widespread subcutaneous and sub-fascial bleeding. [ask.extension.org]

- Animal Bite
Animal Bites Also called: Cat bites, Dog bites Wild animals usually avoid people. They might attack, however, if they feel threatened, are sick, or are protecting their young or territory. Attacks by pets are more common. [icdlist.com]
Venom, like all salivary secretions, is a pre-digestant that initiates the breakdown of food into soluble compounds allowing for proper digestion, and even "non-venomous" snake bites (like any animal bite) will cause tissue damage (Mehrtens 1987, 209) [newworldencyclopedia.org]
Many say it could be the worst of any sting or animal bite. Some have been known to go into shock as a result. Also, the poison can cut off airways. It can kill you if the antivenom is not given soon. [oddee.com]
- Gangrene
[…] cause anaphylactic shock. (6) Cut the wound, (2) since it causes further damage and increases the risk of infection. (5) Then the venom will spread more rapidly (6) Apply a tourniquet.(2) Uninformed tourniquet use can cut off circulation can lead to gangrene [yourownvet.com]
The dangers of tourniquets include the development of ischaemia and gangrene if they are applied for more than about 1½ hours. • Since species diagnosis is important, the dead snake should be taken along to hospital. [cmej.org.za]
Tourniquets or cryotherapy, if used for extended periods may lead to gangrene. The most important first aid measure is rapid transport to comprehensive medical care. [link.springer.com]
Gastrointestinal
- Dysphagia
Clinical features After initial pain and the development of local swelling, paraesthesiae of the tongue and lips, blurring of vision and the loss of the sense of smell (anosmia) and taste, and dysphagia develop, often within 2 - 3 hours of the bite. [cmej.org.za]
Systemic neuromuscular manifestations may be delayed for 12 h and include weakness and lethargy; altered sensorium (eg, euphoria, drowsiness); cranial nerve palsies causing ptosis, diplopia, blurred vision, dysarthria, and dysphagia; increased salivation [merckmanuals.com]
The early signs of gastrointestinal disturbance (3–6 hours) may progress to include numbness of mouth and digits, visual disturbance, dysphagia, neuromuscular weakness and, in severe cases, a potentially fatal respiratory paralysis. [jnnp.bmj.com]

Skin
- Petechiae
The liver and kidneys generally show signs of fatty degeneration, and petechiae and ecchy moses are found in similar situations to those mentioned in connection with cobra-bites, but those resulting from viperine bites are generally more numerous and [booksupstairs.com]
Eyes
- Visual Impairment
Long term poisoning causes burning pains in the hands and feet, a numbing sensation throughout the body, swelling and skin irritations, hair loss, weight loss, cramps, vomiting, nausea, visual impairment, and eventually heart failure. [fmwriters.com]
Neurologic
- Agitation
Active during the day, the snake is known to be easily agitated and highly aggressive. As a warning sign, the snake will make an S shape when ready to strike. [playbuzz.com]
It didn’t take long for the agitated animal to decide it had had enough manhandling. “I took it from Dr. [blogs.discovermagazine.com]

Cobras are distinguished by their large hoods which are spread when the snake is agitated. It is a slender, nervous snake that readily defends itself by biting. It spreads a large hood. [seanthomas.net]
- Flaccid Paralysis
Clinical features Neurotoxicity is characterised by progressive, descending flaccid paralysis. [cmej.org.za]
The specific function selected for the case of elapid snakes, which feed on sleeping lizards, is caused by alpha-neurotoxins, which antagonistically bind to the post-synaptic nicotinic acetylcholine receptor to produce flaccid paralysis [7]. [ncbi.nlm.nih.gov]

The high cost of antivenom isn’t the only problem with the treatment: because relatively few people need the treatment compared to some other illnesses, pharmaceutical companies tend to put antivenom on the back burner. [smithsonianmag.com]

Continued Prevention The snake is almost always more scared of you than you are of the snake. Giving the snake the opportunity to escape prevents most bites. Do not attempt to handle, capture, or tease venomous snakes or snakes of unknown identity. [webmd.com]
These venoms are typically fast acting on nerve tissue and neurotransmitters, often degrading neurotransmitters or depolarizing the axonal membrane for long periods of time, thereby preventing nervous impulses from being conducted. [jrscience.wcp.muohio.edu]
