Q. 'Black Nose Disease', recently seen in the news, is a rare symptom of which viral disease?
Answer:
Chikungunya
Notes: Recently, an infant in Chennai was diagnosed with 'black nose disease,' a rare symptom of chikungunya. This condition, also referred to as 'chik sign' or 'brownie nose,' is characterized by macular pigmentation affecting the nose, appearing weeks after chikungunya fever. Chikungunya, transmitted by Aedes mosquitoes, causes fever and severe joint pain. While the pigmentation is benign and temporary, it highlights the evolving nature of chikungunya symptoms, which can include severe cases like paralysis and low platelet counts.
