The common cold makes most people feel miserable for a few days, but then goes away on its own. However, for people with chronic medical conditions, catching a cold is more likely to lead to serious health problems. Here's a look at some of those conditions and how they can be aggravated by a cold.
The H1N1 flu was a surprise right from the start: a soon-to-be pandemic flu virus that was first identified in kids in the United States. But that's not the only unusual fact about H1N1 flu. Here are eight more surprising developments:
1 Name that flu virus
In April 2009, CDC researchers met to name the newly identified flu virus. The virus came to humans via swine, so the first idea was to call it swine influenza virus. But SIV already stands for simian immunodeficiency virus. Some CDC wags...
For people with heart disease, catching a cold poses a potential danger. While the cold itself usually isn't a danger, cold complications such as lung infections make it difficult to take in oxygen as efficiently as a person should. This makes the heart work even harder to pump oxygen-rich blood throughout the body. This extra demand on the heart can be quite serious for those with heart disease and colds.
Emphysema and chronic bronchitis affect about 15 million adults in the U.S. according to the Centers for Disease Control. Both medical conditions, which are usually caused by long-term smoking, are marked by obstruction to airflow that interferes with breathing. Symptoms of emphysema and chronic bronchitis worsen with the common cold.
The human immunodeficiency virus (HIV) kills or damages cells in the body's immune system, making it more difficult to fight infections such as the cold virus. People with HIV/AIDS are also more likely to get cold complications such as pneumonia.
