Coughing: Is It COVID-19, Flu, Cold, RSV, or Allergies?

Coughing, a prevalent symptom across various illnesses, can often leave us wondering about its root cause. This article delves into distinguishing the coughs associated with COVID-19 from those linked to other conditions such as the flu, common cold, respiratory syncytial virus (RSV), and seasonal allergies.
Features of COVID Cough:
Research Insights: A 2021 study explored the sounds of coughs to detect COVID-19, revealing about two-thirds being dry coughs, typically relentless and producing no mucus. Although an app using AI claims to differentiate COVID-19 coughs, definitive diagnosis still relies on clinical testing.
How to Tell the Difference:
Characteristic Traits: COVID-19 coughs are often dry and persistent, differing from "normal" coughs aimed at expelling irritants. While certain features might indicate a COVID-19 cough, a clinical diagnosis is crucial, considering other hallmark symptoms accompany COVID-19.
Treatment:
Addressing a COVID-19 Cough: If afflicted with a COVID-19-related cough, managing chest discomfort and ensuring restful sleep becomes paramount. Suggestions include staying hydrated, using a humidifier, consuming cold or hot soothing foods, and considering over-the-counter cough aids based on the nature of the cough.
FAQ:
Insightful Queries:
- Duration of COVID Cough: A 2021 study reported 2.5% experiencing a cough lasting over 11 months.
- Night-time Aggravation: Coughs can worsen at night due to postnasal drip or dry air indoors.
- Coughing up Mucus: While a dry cough is common, approximately 33% may experience mucus or phlegm.
- Coughing up Blood: A rare symptom, occurring in about 1–5% of cases, warrants immediate medical attention.
