From difficulty swallowing to sensitivity to air and water, it is necessary to know about the unusual symptoms of rabies and why timely treatment after an animal bite matters. Read on to know more about this and seek timely help.Rabies is linked to a strange symptom called “fear of water”. However, this symptom is not simply a psychological fear. It is linked to the way the rabies virus affects the brain, nerves and muscles involved in swallowing. Some patients can also develop sensitivity to moving air, making even a gentle breeze or fan uncomfortable.Why does rabies cause a fear of water?The term hydrophobia can be misleading. A person with rabies may not actually be afraid of water. Instead, the infection tends to take a toll on the nervous system and can cause painful, involuntary spasms of the muscles involved in swallowing and can steal peace of mind in some people. When the person tries to drink, these spasms may occur suddenly and make swallowing extremely difficult or frightening. As a result, the patient may avoid drinking water and can become distressed even when seeing or thinking about it. Difficulty swallowing can also lead to excessive saliva and drooling. Recognising this symptom is important because it can indicate involvement of the nervous system and usually occurs after the disease has progressed.Also read: World Rabies Day 2026: From Goats To Beavers To Cape Fur Seals, Why Unusual Rabies Cases Are Raising QuestionsWhy can air or wind trigger a reaction?Rabies can also lead to aerophobia, which can be described as an abnormal sensitivity to moving air. Air from a fan or a gentle breeze across the face may trigger discomfort or muscle spasms in some patients and can be disturbing for them.This happens because rabies can interfere with the normal functioning of the brain and nerves that control swallowing, breathing and other muscle movements. Therefore, sensations that are normally harmless can produce an exaggerated response.Also read: Rabies Day Exclusive: ‘We Need To Target The Source’ For A Rabies-Free India By 2030, Says Veterinary EpidemiologistWhat other symptoms should doctors look for?Rabies may initially cause symptoms that appear relatively non-specific, such as fever, headache, weakness or discomfort around the site of an earlier bite. As the infection affects the nervous system, patients may develop anxiety, restlessness, confusion, agitation, difficulty swallowing, excessive saliva, hallucinations, abnormal movements, weakness or paralysis.The unusual symptoms of rabies are a reflection of the infection affecting the nervous system rather than simply a fear or behavioural change. Hydrophobia and aerophobia can occur because normal actions or sensations trigger abnormal muscle spasms. Once neurological symptoms appear, rabies is extremely serious and is almost always fatal. Therefore, the focus should always be on prevention rather than waiting for symptoms. The most important step is preventionRabies is preventable when appropriate treatment is given promptly after exposure. Anyone who is bitten or scratched by a potentially rabid animal, or has saliva exposure to broken skin or mucous membranes, should immediately wash the affected area thoroughly with soap and running water and seek medical care for assessment and post-exposure prophylaxis (PEP).The key message: Do not wait for hydrophobia, aerophobia or other neurological symptoms to appear. By then, the disease may already be advanced. Timely medical attention after a possible exposure can be lifesaving.
