A drop of blood will be the cure

American scientists on the way to the discovery of a fundamentally new method of diagnosis. It will help in the early stages to identify what type of cold sick. This is very important because the symptoms of all respiratory diseases are very similar. This method will allow you to assign patients a much more accurate and specific treatment.

Common viruses that cause influenza and the common cold, imposes a specific imprint on the blood. American scientists say they have found a way to define and use this feature. The researchers hope to develop a test that can give a quick answer: in humans, the standard cold, flu, or other infection that will be very helpful with the choice of treatment, says Cell Host & Microbe.

“This work is still in its early stages of development, but we are optimistic because these findings can lead to new ways of diagnosing infectious diseases,” said Dr. Geoffrey Ginsburg (Dr. Geoffrey Ginsburg) from Duke University in North Carolina (USA), heads the study. Most of the symptoms of respiratory diseases are similar – cough, runny nose, fever, headaches and malaise. There are no good quick test, as evidenced by research Center for control and prevention of morbidity (Centres for Disease Control and Prevention) showing that current tests do not take into account almost half of the possible infections.

Experts say that about half the time of the disease patients with colds do not know what they are sick. Also, it is hard to predict who has the disease can lead to serious complications. Researchers say they have found a set of 30 genes that become active only in patients with advanced symptoms. They were engaged in the study of people with bacterial and viral infections, and compared the activity of these genes. The result was revealed the difference in reaction. “This approach can lead to more accurate and specific treatment,” added Ginsburg. The work is only in its early stages and needs further studies. At the moment, a group of scientists welcomes new volunteers with colds to take part in the study.
