Acute bronchitis usually takes place right after an infection of the upper respiratory tract has occurred like a sinus infection or the common cold. As for chronic bronchitis, there is no exact microorganism that can be pinpointed as a cause but smoking and environmental pollutants are believed to be the major culprits which then may be followed by bacterial or viral infection as the immune system becomes vulnerable.

Common symptoms of both kinds of bronchitis are nasal congestion, muscle pains, fever and chills, sore throat, poor sleep, and dyspnea (common in chronic bronchitis). Basically, the symptoms of bronchitis are similar to that of the common cold. It starts with an irritation at the back of the throat and as it gets worse, cough will enter the picture which may come with phlegm. If the phlegm is streaked with blood, it is best to consult a physician.

Although the name ‘swine flu’ brings up a lot of extra fear and worry, it is important to note that swine flu is just an influenza A H1N1 virus.

That means that it is just another type of flu virus, just like that causes our typical seasonal flu symptoms. The big difference is that the current swine influenza A (H1N1) virus has components of pig and bird influenza viruses in it, so that humans don’t have any immunity to it. That makes it more likely to become a pandemic virus (have the ability to cause a global outbreak) if it can easily spread from person-to-person.

Symptoms of swine flu are like regular flu symptoms and include fever, cough, sore throat, runny nose, body aches, headache, chills, and fatigue. Many people with swine flu have had diarrhea and vomiting. Nearly everyone with flu has at least two of these symptoms. But these symptoms can also be caused by many other conditions. That means that you and your doctor can’t know, just based on your symptoms, if you’ve got swine flu. It takes a lab test to tell whether it’s swine flu or some other condition.

So far, even as you see swine flu cases increase on this swine flu map, experts don’t know if this swine influenza A (H1N1) virus will become a pandemic strain of flu. It could or we just continue to see sporadic cases for a few weeks or months until it stops.

We do know that swine flu symptoms are just like seasonal flu symptoms. Signs of a more serious swine flu infection might include pneumonia and respiratory failure.
