Chennai: Canine Distemper Cases Rising During Monsoon, Winter
Imagine a nasty cold for dogs called Canine Distemper, which spreads easily and can be deadly.
It's like a flu that affects their breathing, tummy, and even makes them act strangely.
Scientists in Chennai found that this disease is common, especially during the rainy and colder seasons.
They studied many dogs and learned how the weather, like rain and temperature, affects the spread of the disease.
The virus can live longer in cold weather and spreads through the air and contact.
If dogs aren't vaccinated, they can get very sick.
Scientists suggest that if more long-term studies linking weather and disease patterns are needed, as the virus could potentially affect other animals or humans.
Canine Distemper (CD), a contagious viral disease, affects dogs, particularly during monsoon and winter months.
A study in Chennai found an 82% positivity rate for CD in 1,185 dogs between 2011 and 2019.
The virus spreads through saliva, urine, and contact with infected secretions and surfaces.
CD cases peak in November, with higher prevalence in densely populated northern Chennai areas.
Researchers emphasize the need for more long-term studies linking weather and disease patterns, also the potential for the virus to cross over to humans.
