Habitat and Distribution
Range of Russell’s Viper
The Russell’s viper, or Daboia russelii if you’re into the Latin groove, makes its home all over the Indian subcontinent. It’s a skilled squatter in countries like India, Pakistan, Sri Lanka, Bangladesh, Nepal, and some parts of Southeast Asia including Myanmar, Thailand, and Cambodia (Wikipedia). But keep this in mind: some of its relatives in Southeast Asia got their own species label now, Daboia siamensis, strutting their stuff separately.
| Country | Is Russell’s Viper Here? |
|---|---|
| India | Yes |
| Pakistan | Yes |
| Sri Lanka | Yes |
| Bangladesh | Yes |
| Nepal | Yes |
| Myanmar | Yes |
| Thailand | Yes |
| Cambodia | Yes |
In India, this viper’s like a local celebrity, especially in Punjab, the West Coast, the hills, and let’s not forget our friends down south in Karnataka. It’s a bit shy while visiting the Ganges Valley, northern Bengal, and Assam though (Wikipedia). One might catch it lounging in coastal lowlands, plains, or even moseying through suitable hilly spots.
Preferred Habitats
Russell’s viper is quite the adaptable critter when it comes to picking hangouts, though it gives dense forests a hard pass. They’re into open spaces—think grassy or bushy spots, forested plantations, farmlands, and scrappy second-growth forests like scrub jungles (Animalia). These comfy habitats spread across plains and coastal lowlands, but the snake isn’t afraid to set up shop as high as 2300–3000 meters up, should the scenery be right (Wikipedia).
| Habitat Type | Do They Like It Here? |
|---|---|
| Open grassy areas | Yes |
| Bushy areas | Yes |
| Forested plantations | Yes |
| Farmland | Yes |
| Scrub jungles | Yes |
| Dense forests | No |
| Marshes and swamps | No |
| Rainforests | No |
Where folks live, so do rodents, which are Russell’s viper’s idea of a comfy meal. So you’ll find these snakes where humans are hanging out too—plains, coastal lowlands, savannas, foothills, and even up in the montane regions (The Wonderful Wildlife of Samloem).

Getting to know where Russell’s viper calls home helps out a ton in sketching out plans to keep folks safe from snakebites. This is no small thing for people living nearby these serpents. Snag more scoop in our sections on interaction with humans and global health implications.
Interaction with Humans
Risk Factors for Snakebites
Folks working outdoors in cities or country areas better watch their step – Russell’s vipers are out there, slithering and seeking rodents that hang ’round human spaces like a cheap suit (Wikipedia). While these sneaky reptiles aren’t lining up for city apartments like cobras or kraits, they still pose a threat to farmhands or construction folks getting their daily grind on.
| Factor | Description |
|---|---|
| Occupation | More bites for farmers, builders, and anyone braving the great outdoors. |
| Urban Proximity | Viper visits spike near city edges thanks to the rodent rush brought on by human hustle. |
| Time of Day | Mostly night creeps but also roam during cooler days, upping your chances of a brush-in. |
While you’d think nights are their party time, Russell’s vipers don’t mind stepping out during cooler days, giving them more chances to bump into humans (The Wonderful Wildlife of Samloem). These hunters stalk, chomp, and move on, trailing bigger meals like rodents as they mature, bringing them all too close to our neighborhoods.
Human Settlement Preferences
Russell’s vipers like to hang where people aren’t scarce and more importantly, where mice run amok. This rodent buffet brought to you by human habitation can be a real pickle in farmlands and smaller towns.
A whopping 750.19 million souls, which is about 10.95% of Earth’s people, sit within snake zones yet find themselves more than an hour’s drive from a hospital, complicating bite treatments (NCBI). It’s no breezy paradise for those in remote spots missing decent healthcare, leading to more doomed outcomes from bites. Folks in places like Sudan, Algeria, Indonesia, Papua New Guinea, Colombia, and Peru need to be on high alert.
| Region | Vulnerable Population (Millions) | Factors |
|---|---|---|
| Remote Areas | 146.70 | No hospitals equals higher risk of nasty snakebite outcomes. |
| Global Regions | 750.19 | Far from city clinics, risking late snakebite care. |
In Tamil Nadu, India, snake wranglers typically don’t get the education or support they need, often buying their own gear and meds. This DIY approach ups the danger during snake rescues, which ramps up the risk of bite cases (PLOS Neglected Tropical Diseases). This also emphasizes the need for solid training and gear for those in the thick of dealing with Russell’s vipers.

Envenomation Symptoms
Spotting the signs of a Russell’s Viper bite can mean the difference between life and death. This sneaky serpent, known as Daboia russelii, slithers across parts of Asia and is a notorious danger, especially in the Indian subcontinent.
Effects of Russell’s Viper Bite
Russell’s Viper’s venom likes to party hard with your body, but not in a fun way. It packs a punch, with adult snakes capable of delivering a nasty cocktail of 130-250 mg of venom per chomp. The lethal dose for humans? Just a stingy 40-70 mg. This venom soup meddles with your blood, muscles, and organs in unpleasant ways.
Common Symptoms
- Pain and Swelling: Feel it right where it bites.
- Bleeding and Dead Tissue: Not just bruises, but tissue starts waving goodbye.
- Body-wide Problems: Blood pressure takes a dive, heart rate lags, plus you might regurgitate or your face could puff up.
- Worst-Case Scenarios: Your kidneys might give up, your blood starts playing evil hornet, and even your pituitary gland gets demolished Wikipedia.
| Symptom | Frequency (%) |
|---|---|
| Pain and Swelling | 100 |
| Bleeding | 60 |
| Necrosis | 40 |
| Vomiting | 55 |
| Kidney Failure | 35 |
| DIC | 25 |
| Pituitary Damage | 15 |
Importance of Early Treatment
Getting a fast move on to the ER can dodge the nastiest aftermath of a Russell’s Viper bite. Antivenom is the superhero here, and the quicker it’s on the scene, the better. Efforts are rolling to make antivenom a household name, specifically for these fang attacks. Chittagong University’s Zoology Department hit the ground running in 2023 with a project aiming high at just this issue (The Financial Express).
Key Treatment Steps
- Steadying the Ship: Keep the patient stable and keep tabs on their vitals.
- Antivenom Superstar: Don’t stint on administering antivenom pronto.
- Combat Symptoms: Tackle pain, swelling, and any hooraying blood pressure plummets.
- Hospital Hook-Up: Intensive care for kidney bails or massive bleeding’s a must.

Global Health Implications
Snakebite Vulnerability
Snakebites are a real headache for many parts of the globe, especially places crawling with venomous snakes. Take a look at some numbers: according to NCBI, around 6.85 billion folks live where snakes are known to slither, with about 146.70 million of them in far-off spots where quality healthcare might as well be a myth. This ups their chances of suffering from snakebites and possibly kicking the bucket. Being stuck in these places comes with its own set of troubles, like struggling to get to medical help or the much-needed antivenom.
Let’s talk about Bangladesh. There’s a nasty fella there, Russell’s viper, among about 100 snake species (37 of these can cause serious harm). With snakebites causing a lot of illness and death, numbers are showing 6,041 yearly deaths from 623 snakebites per 100,000 folks (Mongabay). Shows you just how vital it is to come up with plans to deal with these biting issues in places that need it the most.
| Region | Folks at Risk | People Out in Remote Spots |
|---|---|---|
| Global | 6.85 billion | 146.70 million |
| Bangladesh | 6,041 deaths/year | – |
Access to Antivenom
Getting hold of antivenom, the only thing that’s got snakebites pegged, ain’t easy in way too many places. Out of 278 snake types looked at, antivenoms exist for just 119 of them (43%), leaving 159 types (57%) out in the cold. This shortage bites even harder in West and Central Africa, South America, and South Asia, where snakebites are no rare sight.
There’s also the matter of time: around 750.19 million people live over an hour away from places where they can get quick help. This delay in care for snakebite victims makes a bad situation worse. Countries feeling the heat include Sudan, Algeria, Indonesia, Papua New Guinea, Colombia, and Peru.
| Snake Type | Antivenom Around? |
|---|---|
| Checked Out Types | 278 |
| Antivenom Available | 119 (43%) |
| Missing Antivenom | 159 (57%) |
Healthcare Accessibility
The Healthcare Access and Quality (HAQ) Index shows just how different the situation can be between folks at risk of snakebites when it comes to getting treated. About 272.91 million people (65.25%) in the lowest HAQ Index range are stuck facing snakes without any surefire treatment. Compare this to 519.46 million folks (27.79%) in the highest HAQ Index range, who have better luck.
If you’re curious to know more about Russell’s Viper and its thrills (not the good kind), take a peek at russells viper bite, russells viper venom, and russells viper antivenom.
| HAQ Index Rank | Population at Risk | Odds of No Good Treatment |
|---|---|---|
| Bottom (1st Rank) | 272.91 million (65.25%) | High |
| Top (10th Rank) | 519.46 million (27.79%) | Low |
So, what’s the fix? To tackle these slippery snake issues, we need to boost access to healthcare and make sure antivenoms are readily available in snakebite-prone spots with lousy healthcare setups.
Local Impact in Specific Regions
Sri Lanka’s Snakebite Situation
Sri Lanka’s wrangling with snakebites is no walk in the park, with Russell’s viper often in the spotlight. The island’s snakebite patterns reveal Russell’s viper as a common offender, yet its role is sometimes downplayed compared to the flashy cobras (NCBI). Hospital trips tell the tale that Russell’s viper is quite the frequent biter, especially in areas caught between the dry and wet.
A big sticky point in Sri Lanka is the hit-and-miss healthcare access post-bite. When the countryside folks are bitten and medical help is miles away, speed is of the essence. Curious about dealing with such serpentine encounters? You’ll find handy pointers in our article on Russell’s viper bite treatment.
Bangladesh’s Resurgence of Russell’s Viper
Bangladesh isn’t lounging around either, as Russell’s viper slithers back onto the scene, increasing snakebite stats and fatalities. Among nearly 100 snake kinds slithering in Bangladesh, 37 are venomous, Russell’s viper included (Mongabay). Studies estimate about 6,041 fatalities a year from 623 snakebites per 100,000 folks, painting a dire picture.
The uptick in Russell’s vipers is pushing Bangladesh to whip up a special antivenom, tackling the health scare head-on. Upping healthcare accessibility and spreading the word about dodging bites could make a big difference. Want the scoop on their venom? Peek at our write-up on Russell’s viper venom.
| Region | Estimated Fatalities (per year) | Venomous Snake Species Present |
|---|---|---|
| Sri Lanka | Lots, but not pinned down number-wise | Russell’s viper, cobras, hump-nosed viper |
| Bangladesh | 6,041 | 37, including Russell’s viper |
Getting a handle on the local sway of Russell’s viper in spots like Sri Lanka and Bangladesh sheds some light on the bigger picture of Russell’s viper distribution. Combating such issues with spruced-up healthcare and precise antivenom creation is key to cutting down the nasty bite aftermath in these regions.

Unique Characteristics
Meet the Russell’s viper, a snake that’s not just fascinating, but a bit of a hazard too. By diving into its quirks, we get a peek into how this slithery creature thinks and adds to its family tree.
Night Owl Tendencies
This viper gets lively when the sun goes down, adjusting its schedule based on how toasty or chilly the weather is. On hot nights, it’s all about prowling in the moonlight, sneaking up on dinner while staying under the radar. But when the air nips at night, it switches gears and takes its hunt to the day (The Wonderful Wildlife of Samloem). It’s a sneaky stalk-and-bite kind of hunter—takes a bite, lets go, and then just waits for the food to stop fighting back. As it grows, its menu starts featuring bigger critters like rats, which sometimes drags it close to people looking for a meal.
| Time of Activity | What’s Happening? |
|---|---|
| Night (Warmer Weather) | On the prowl, hunting |
| Day (Cooler Weather) | Amped up activity, hunting |

Baby Boom Patterns
These vipers play it live when it comes to baby-making. Instead of messing around with eggs, they skip straight to popping out baby snakes. Love season kicks off from April to August, and after about six to seven months of waiting, you might find anywhere from 20 to 40 baby vipers borrowing mom’s space. You better bet the mama finds a cozy, secret spot to keep her little ones safe from any prying eyes or paws.
| Baby-Making Details | What’s the Deal? |
|---|---|
| Type of Birth | Live birth (Viviparous) |
| Breeding Time | April through August |
| Baby-Waiting Time | 6 – 7 months |
| Number of Babies | 20 – 40 little ones |
