Common Monsoon Health Myths
Myth: Rainwater itself causes illness.
Rain does not directly cause infections. Illnesses are usually caused by viruses, bacteria, contaminated food or water, or mosquito bites.
Myth: Taking antibiotics prevents seasonal infections.
Antibiotics do not prevent viral illnesses and should only be taken when prescribed by a qualified healthcare professional.
Myth: Herbal drinks alone can prevent all infections.
Healthy beverages may be part of a balanced diet, but no drink can guarantee protection against infections. Good hygiene, proper nutrition, and vaccination where recommended are also important.
