While an investigation is on within the case of the dying of a 14-year-old Ghaziabad boy from rabies, allegedly after a canine chunk, the incident has forged a evident highlight on myths and misconceptions round canine bites and rabies.
“Mortality rate in human rabies cases is 100 percent. Unfortunately, no cure has been found for rabies. Most cases of rabies occur from not receiving the recommended treatment following a bite or scratch from an infected animal,” says Dr Rajeev Jayadevan, Member, Public Health Advisory Panel, Kerala State Indian Medican Association (IMA), who has been extensively researching canine bites and rabies.
Rabies and canine bites in India
Remarkably, India bears the grim burden of accounting for a staggering 36 p.c of worldwide rabies deaths, a permanent public well being problem that calls for our consideration.
Dr Jayadevan says that as per information from WHOroughly 20,000 deaths happen in India yearly from rabies. On a worldwide scale, rabies stands because the Tenth-largest explanation for dying resulting from infectious ailments. Meanwhile, India additionally shoulders a crushing 65 p.c of rabies-related fatalities inside the South East Asia area.
“About 30-60 percent of reported rabies cases and deaths in India occur in children under the age of 15 years, as bites that occur in children often go unrecognised and unreported,” says WHO.
Doctors declare {that a} majority of human rabies circumstances in India are resulting from canine bites.
Despite the brand new animal contraception guidelines of 2023, which lay down steps to sterilise animals and regulate their inhabitants in a fashion that complies with numerous orders by the Supreme Court, the variety of incidents of stray canine bites and mauling of youngsters throughout the nation is growing drastically.
There have been a number of circumstances of pet canine bites too.
Despite the norms requiring states to implement contraception and anti-rabies drives concurrently, Kerala alone, within the 12 months 2022, reported 1.2 lakh canine chunk circumstances. “In the span of one year, 18 people died due to rabies in Kerala, indicating serious concern,” provides Dr Jayadevan.
Meanwhile, Dr NR Ramesh Masthi, Professor and HOD of Community Medicine at Bengaluru’s Karnataka Institute of Medical Sciences (KIMS) Hospital, says, “Bengaluru alone has reported four rabies cases in the last month.”

Myths about animal bites
Doctors make clear that the first false impression is that rabies happens solely resulting from canine bites. This just isn’t true. While human rabies is generally transmitted by means of canine bites, Dr Masthi clarifies that bites from contaminated cats, monkeys, jackals, or every other animal also can go on the illness.
Meanwhile, it is usually vital to know that not simply bites, however even contaminated animal saliva on damaged pores and skin, internal mouth, or nostril can transmit rabies.
Dr Jayadevan explains that when an contaminated canine bites, the canine’s saliva is deposited within the open wound. Then, the an infection enters the particular person’s nervous system and slowly discover its method to the mind and spinal twine.
“The speed of travel along the nerve might range from 5 to 100 mm per day. Depending on the conditions, the virus may take several days or weeks to show symptoms of rabies. The end result is death,” he explains.
However, after the canine chunk, Dr Masthi says that, in his scientific follow, he has seen many individuals resorting to the appliance of turmeric powder and leaves as a measure to forestall rabies. “People use turmeric or some kind of leaves on the wound and let it be. This is dangerous,” he explains.
Dr Masthi provides that individuals additionally are inclined to imagine that provided that there may be seen bleeding, it causes rabies.
“The truth of the matter is that even a single drop of blood means that there is a cut in the skin and the rabies virus can enter the human body,” Dr Masthi explains.
The different main fable is that puppies don’t chunk and in the event that they do, their bites don’t transmit rabies. The truth is that puppies do chunk, even whether it is playfully, and so they can transmit the illness.
“In many cases, puppy bites are ignored and several times, they are unvaccinated for many months. This leaves them more vulnerable and if they become infected, their bite can lead to rabies deaths,” explains Dr Masthi.
This reinforces the need of accountable pet care and vaccination programmes to manage rabies.

Can vaccinated dogs transmit rabies?
Doctors clarify {that a} vaccinated canine is unlikely to transmit rabies, however they are saying that it’s important to know the nuances of rabies vaccination to get a transparent image.
When a canine receives a rabies vaccine, it stimulates the canine’s immune system to provide antibodies towards the rabies virus. These antibodies function a protection mechanism, successfully neutralising the virus if the canine have been to come across it.
However, there are just a few vital caveats to think about, clarify the medical doctors. While the effectiveness of a rabies vaccine can fluctuate relying on the kind of vaccine used, the canine’s total well being, and the administration course of, no vaccine can guarantee one hundred pc immunity.
Meanwhile, dogs usually obtain rabies vaccinations on a particular schedule, with boosters wanted periodically. If a canine misses a booster shot or the vaccine’s efficiency wanes, their safety might lower.
Also, if a vaccinated canine is bitten or uncovered to a rabid animal, there may be nonetheless a small threat of transmission. This is as a result of the virus might be current on the website of the chunk earlier than the canine’s immune system has an opportunity to neutralise it.
Highlighting a major problem within the area of rabies prevention, Dr Masthi explains, “There are a very few labs available to check the antibody titers in animals, particularly dogs, after vaccination.”
This implies that many instances, the antibodies required for cover aren’t detected regardless of vaccination. It’s a regarding subject that underscores the necessity for higher monitoring and analysis on this space.

Can people get rabies even after the vaccine?
While rabies is certainly a vaccine-preventable illness and the vaccine is given freed from cost in any respect authorities hospitals, Dr Jayadevan says that there are just a few undesirable outcomes that would happen regardless of therapy for rabies.
After reviewing scientific literature from world wide, Dr Jayadevan says that deep bites in areas wealthy in nerve provide, such because the face and fingers, make it simpler for the virus to invade the nerves.
Citing one case of a five-year-old from Chandigarh, who had died after she had extreme facial wounds attributable to a rabid canine chunk, Dr Jayadevan says that regardless of receiving the immunoglobulin vaccine, she died.
Similarly, he says that it’s dangerous if the sufferer suffers from a number of wounds because the virus might then enter by means of a number of websites. This may want extra care, he provides.
Importantly, a chunk on the leg will contain longer journey distance to the mind and spinal twine because it provides time for our immune system to overpower the virus, however a chunk on the top or neck may cause it to succeed in the mind quicker.

Importance of correct wound care after canine chunk
One vital side Dr Masthi emphasises is the significance of correct wound care. “Many people resort to local practices, like applying turmeric, which, in reality, acts as an irritant and does not kill the virus,” he explains.
“The most vital treatment is washing the wounds with soap and water, which can eliminate 80-95 percent of the virus,” he says. This easy but efficient measure is commonly uncared for however could make a major distinction.
A research from the National Institute of Communicable Disease (NICD) India, achieved in 2021-2002, reveals that about 40 p.c of individuals didn’t wash the injuries earlier than arriving on the hospital, and even on the hospitals, just a few of them routinely carried out wound washing.
Doctors insist that after washing, they need to keep away from dressing or bandaging the wound.
Meanwhile, the rabies vaccine must be saved within the fridge between 2 to eight levels and is often given on days 0 (the day of the chunk), day 7, and 21 days. Post-vaccination, an individual enjoys full safety for 3 years.
After this era, the efficacy may fluctuate. However, it is suggested that if there’s a repeat canine chunk, after taking a vaccine, it’s nonetheless vital to hunt medical help.
Another space the place misconceptions can have life-altering penalties is the categorisation of publicity. “Wrong categorisation of exposure, such as classifying a Cat-3 exposure as Cat-2, can lead to the denial of life-saving local administration of anti-rabies serum,” Dr Masthi warns. He careworn that native infiltration of rabies immunoglobulin on the website of the chunk is essential for neutralising the virus.
Dr Masthi provides that overconfidence amongst these uncovered to bites, considering that nothing will occur to them, is a grave concern. Rabies is a relentless illness and early intervention is crucial.

Symptoms of rabies
The signs of rabies usually progress in phases and might fluctuate in depth. According to medical doctors, the preliminary signs are fever, headache, fatigue, nausea, vomiting, anxiousness, restlessness, ache, itching, tingling sensation on the website of the wound.
For livid rabies, there may very well be acute neurological signs like agitation and hyperactivity, hallucinations, extreme foaming on the mouth, problem in swallowing resulting in concern of water, seizures, aggression, and erratic behaviour.
Even additional, the signs might worsen, reaching a stage of paralysis, lack of coordination, respiratory failure, and finish in a coma or dying.
Meanwhile, medical doctors insist that individuals mustn’t sit and anticipate the contaminated animal to exhibit signs of rabies. They should search medical consideration instantly after the chunk or scratch. “Over-treatment is better than no treatment leading to death,” quips Dr Masthi.
However, contaminated animals may exhibit signs of over-salivating, unnecessarily biting, displaying aggression, resulting in dying in 7-10 days of the chunk incident.

How shortly will signs seem?
The incubation interval, which is the time between being uncovered to the virus and the onset of signs, for rabies can fluctuate. On common, it ranges from a number of weeks to a number of months, however it may be shorter or longer in some circumstances.
The incubation interval relies on numerous components, together with the situation and severity of the publicity, the kind of rabies virus concerned, and the person’s immune system response. In some uncommon cases, signs can seem inside days of publicity, whereas in others, it might take years for signs to manifest.
It’s vital to notice that when signs of rabies seem, the illness is almost all the time deadly. This underscores the urgency of searching for medical consideration and receiving post-exposure prophylaxis (PEP) promptly after a possible rabies publicity.
PEP is extremely efficient in stopping the onset of rabies signs when administered earlier than the virus reaches the central nervous system.
To be protected, it’s essential to seek the advice of a healthcare skilled instantly after any potential rabies publicity to evaluate the necessity for PEP, relatively than ready for signs to develop.
