why is there no cure for a cold
ItБs been a long-running joke for some time now, but the day weБve been waiting for could be here. Scientists may have just found a cure for the common cold. Researchers at Edinburgh Napier University have discovered possible new treatments based on antimicrobial peptides that occur naturally in humans and animals, and increase the bodyБs natural response to infection. A five-year study into peptides from different mammals found that they all have properties that can combat rhinovirus Б the main virus responsible for the common cold in humans. Dr Peter Barlow, associate professor of immunology at the university, did warn that the research is in its early stages. However, he added: БWe will ultimately be looking to develop drug treatments that have the potential to cure the common cold. Б
For the projectБs next step, scientists are going to try to modify the peptide to make it better at killing the rhinovirus, he said. БThere is no cure and no vaccine, so the development of effective therapies for human rhinovirus, the main causal agent of the common cold, and one of the most common causes of viral respiratory tract infections, is an urgent requirement,Б Dr Barlow said. БThis study represents a major step towards finding a treatment. Б Finding an effective treatment for colds could also help sufferers of more serious lung conditions, such as asthma and chronic obstructive pulmonary disease (COPD), for whom viral infections can pose a serious health risk. Earlier research by Dr Barlow had found there was potential for antimicrobial peptides to help tackle the influenza A virus as well. The latest бе200,000 study, funded by the Chief ScientistБs Office and medical research charity Tenovus Scotland, expanded this work to explore the possibility of using antimicrobial peptides from pigs and sheep to fight the rhinovirus.
Using peptides synthesised in the lab, researchers Filipa Henderson Sousa and Dr Victor Casanova assessed the impact of the different peptides on lung cells infected with human rhinovirus. The peptides successfully attacked the virus, and could provide clues for developing novel treatments based on peptides found in nature. Dr Barlow said: БThis is an exciting discovery and our next steps will be to modify the peptide to make it even better at killing this virus. БThis research is still in the early stages, but we will ultimately be looking to develop drug treatments that have the potential to cure the common cold. Б is the most frequent disease humans suffer from, and most people get a cold at least once or twice a year. A cold is a viral infection of the upper respiratory tract and is characterised by fever, coughing and sneezing, sore throat and a runny nose. (Fever in colds is usually below 37. 8 C. ) There are many virus strains that can cause colds, the most common of which are. An illness can be approached in three ways: 1. "An ounce of prevention is better than a pound of cure. '' This means that the best way to "deal" with e. g. a cold is to avoid getting one in the first place. 2. If, however, you're unfortunate enough to become ill, the best way to approach the situation is to eliminate the cause of the disease, or, in other words, cure it. 3. But if the disease can't be cured (and just needs to run its course), the only option you're left with is to treat the symptoms and make yourself as comfortable as possible. Keep your immune system strong A good way to avoid getting a cold is to stay away from cold viruses.
This is achieved by avoiding contact with anyone who might be contagious. It is also good to regularly, especially after spending time in public areas. Read: The best way to stay healthy, though, is to make sure your immune system is strong enough to ward off those cold viruses. According to, the best way to keep your immune system strong and healthy is to abide by the following general good-health guidelines: Don t smoke. Eat a diet high in fruits, vegetables, and whole grains, and low in saturated fat. Exercise regularly. Maintain a healthy weight. Control your blood pressure. Drink alcohol only in moderation. Get enough sleep. Take steps to avoid infection. Get regular medical screening tests. Can one cure a cold? Many people believe that can cure a cold. This is wrong, because colds are caused by viruses, not bacteria, so antibiotics will have no effect. A study published in the Journal of Clinical Microbiology on 200 young adults with common colds showed that bacterial infections were rare, supporting the concept that the common cold is almost exclusively. Furthermore, taking antibiotics when you don t need them can also lead to. Read: What about a cold shot? By creating immunity against a particular disease, vaccination prevents us from getting that disease. It is therefore more of a preventive measure than a cure. Millions of people take their yearly flu shot, but cold vaccinations have proven not to be a feasible option and a has found a lack of evidence on the effects of vaccines for the common cold in healthy people. According to Thomas Smith, PhD, from the University of Texas, there are over 100 serotypes of rhinovirus, making it unlikely that there will ever be a traditional vaccine for the common cold using.
Also, having a cold may be a nuisance, but it is not a serious or life-threatening disease, which is why it is not high on the list of diseases that have to be cured. Currently the best bet for an anti-cold medicine may be something called broad-spectrum antivirals, which would target a number of different viruses. This research is however in its infancy. In 2011 Draper Laboratory in Cambridge developed a compound called, which "is designed to treat or prevent infections by a broad spectrum of viruses, just as existing antibiotics can treat or prevent infections by a broad spectrum of bacteria". Treating a cold Here are a few examples of popular home remedies that may or may not make you feel better : Herbs like echinacea, goldenseal and ginseng Ginger, honey and garlic Zinc and vitamin C? There are studies that confirm that zinc gluconate lozenges are effective for treating the common cold. One randomized, found that zinc gluconate in the form and dosage studied significantly reduced the duration of symptoms of the common cold. Nobel Prize winner, Linus Pauling, was almost single-handedly responsible for the belief that vitamin C could significantly decrease the incidence of the common cold. This gave rise to the controversial belief that large doses of vitamin C could reduce the risk of catching a cold as well as reduce its severity and duration. From a medical point of view, it is therefore safe to say that there is no cure for the common cold, and apart from not getting a cold in the first place, once you've got it, there s currently no getting rid of it. The only option that remains is to wait for the illness to run its course and to treat the symptoms as effectively as possible. Read more:
