I've been having a persistent cough, i don't have a sore throat but i'm worried, especially with the covid-19 outbreak as this is one of the symptoms.

Perhaps, get tested : Daily changes in news on Covid-19 means we can only offer best guess today. Fever and cough still are common symptoms, but some people have no symptoms at all. You don’t mention fever, so chances are your problem is not the pandemic disease. Regardless, other symptoms of chills, muscle aches have also been reported, adding to its confusion with regular flu and or colds, even allergies.

Whooping: This is a specific sign. If indeed you have a whooping cough that is likely what you have. This is primarily caused by Bordatella pertussis, but can be caused by Mycoplasma, Chlamydia trachomatis, and chlemydia pneumonia. Adenovirus can be a cause too. This can last up to 6 weeks. Coronavirus at age 25 has statistically been common, but mild viral process for most. Coronavirus does not cause whoop

Warm Water...: Under these circumstances: Gargle with warm water and salt or Vinegar and water after meals and at night. Avoid Cold or iced drinks. Take Aleve or Ibuprofen for fever or pain & See the PCP for Tetracycline or Doxycycline and if wheezing, Inhaler.
