Persistent dry cough and runny nose for weeks? Doctor?« Back to Previous Page

Based on your description, this sounds far less like a common cold and far more like a classic case of Indoor Air Quality (IAQ) related illness, often exacerbated by the UAE's climate and building practices. The fact that symptoms are worst in the evening with the AC running is a massive red flag.

That persistent dry cough and runny nose are hallmark symptoms of exposure to low-level irritants. While the humidifier helps with simple dryness, it does nothing to address the primary culprits I suspect in your Jumeirah villa:

1. Microbial Contamination in the AC System: The evaporator coils and drip pans of AC units are a breeding ground for mold and bacteria if not professionally cleaned and maintained every 6 months, as recommended by Dubai Municipality guidelines. When the AC blasts, it aerosolizes these contaminants directly into your breathing zone.
2. Dust and Particulate Matter (PM): Fine desert dust (silt) infiltrates homes and accumulates in ducts. This dust often carries allergens and can itself be a severe irritant to the respiratory tract.
3. Volatile Organic Compounds (VOCs): From off-gassing furniture, cleaning products, or air fresheners.

A "Dubai cough" from a single event might clear up, but symptoms persisting for weeks indicate a continuous exposure source within your home environment. This is not something to ignore, especially with a toddler involved, as their developing systems are more vulnerable.

I strongly advise you to see a doctor to rule out any underlying respiratory infections. Simultaneously, you need to identify the source. This isn't just about cleaning; it requires a professional inspection to measure particulate levels, humidity at the coil, and conduct microbial sampling if necessary.
