Monsoon in Thane — what to actually worry about, and what to ignore.
Every June we see the same pattern in the clinic — dengue, leptospirosis, gastro, and a lot of wet-season anxiety. Here's a calm guide to the four monsoon illnesses that matter, and the symptoms that should pull you in.
By Dr. Pratik Chhajed, MD · Updated for monsoon season
Thane in monsoon is a beautiful, complicated, slightly damp place. The same rain that makes the hills green also fills standing puddles, drains, and water tanks where mosquitoes breed. Most monsoon illness is preventable. The four that aren't — and that arrive in clinic every July and August — deserve a calm, plain explanation.
Dengue — the platelets question, decoded
Dengue is the headline disease of every Thane monsoon, and it deserves its reputation. The mosquito (Aedes aegypti) bites in daylight, breeds in clean still water, and transmits a virus that causes high fever, severe body pain, pain behind the eyes, and — in a smaller fraction — a drop in platelet count.
The thing patients worry about most is platelets. Here is what I tell them: most platelet drops are not dangerous. The body recovers them. We watch the count, we hydrate, we wait. Platelet transfusion is reserved for very specific situations — counts under 10,000, or any active bleeding. The "platelet panic" that drives people to demand transfusions at 80,000 is mostly unnecessary and sometimes harmful.
Most dengue is managed with fluids, paracetamol, and time. Not transfusions.
Leptospirosis — the wading-through-water risk
Leptospirosis is the disease nobody talks about until they've seen it. It spreads through water contaminated with rat urine — most commonly when somebody wades through a flooded street with an open cut on the foot. Symptoms come 7–14 days later: fever, severe muscle pain (particularly calves), red eyes, and sometimes jaundice.
The treatment is simple antibiotics, started early. The diagnosis is missed often because patients don't connect the wading episode with the fever two weeks later. If you've waded through floodwater and develop fever within two weeks, please mention it.
Monsoon gastro — the 24-hour rule
Stomach bugs spike in July and August — contaminated water, food sitting longer in humid kitchens, more outside eating. Most gastroenteritis is self-limited: vomiting and loose stools for a day or two, then recovery.
- The 24-hour rule: if you can keep ORS down and your urine output is normal, ride it out at home.
- Come in if: vomiting prevents fluids, blood appears in stool, fever crosses 39°C, or symptoms persist past 48 hours.
- Skip the antibiotics unless we say so — most monsoon gastro is viral.
Viral coughs that won't quit
The post-viral cough — that dry, irritating cough that hangs around for three weeks after a viral illness — is the single most common monsoon complaint after the fever passes. It is almost never a problem. It is your airway healing, slowly, in damp air.
Cough syrups help only marginally. Steam inhalation, warm fluids, and patience help more. We escalate only if the cough produces coloured sputum, comes with breathlessness, or persists past four weeks.
Wet hair will not give you pneumonia. "Monsoon weakness" is real but it is mostly poor sleep and reduced sunlight, not a deficiency syndrome that requires three supplements. Sleep, fluids, and one daily walk on a dry afternoon do more than most monsoon vitamin shelves.
When to come in, plainly
If you're seeing a high fever with body pain, abdominal pain, or any bleeding, please come in the same day. The first 48 hours of dengue are the ones that matter.
If this sounds like you, book a slot.
