H1N1 Virus can be killed with water

...Acidic ozone water, that is.

(PhysOrg.com) -- Scientists have found that acidic ozone water can deactivate H1N1 viruses very effectively, offering a promising disinfectant for the millions of people trying to avoid the disease. Acidic ozone water (AOW) is made from regular tap water mixed with a small amount of acid such as hydrochloric acid, along with an ozonized gas that can be produced in the lab. After deactivating the virus, the substance eventually decays into plain water, leaving no residue or harmful materials in the environment.

Scientists Han Uhm of Ajou University in Korea, along with Kwang Lee and Baik Seong of Yonsei University in Korea, have published the results of their study on the H1N1 disinfectant in a recent issue of Applied Physics Letters. Besides being environmentally benign, AOW also has the advantage that it may cost significantly less to prepare compared with chemical disinfectants.

During the past several months, H1N1 has infected thousands of people worldwide and has proven to be a highly contagious disease. Attempts to combat the disease have included preventative vaccines and the use of disinfectants to prevent the spread of the disease. However, most of these disinfectants have chemicals that can harm the environment.

In the current study, the researchers found that they could make neutral water acidic by mixing a very small amount of hydrochloric acid into the water. Adding just 22 grams of hydrochloric acid to one ton of neutral water can change the pH value of the water from 7 to 4. As the scientists explain, the negative chlorine ions have a sterilizing effect on viruses, and a strong acidity in general also has a sterilizing effect.

Although acidic water itself can partially inactivate the H1N1 virus, the scientists also added an ozone gas concentration of more than 10 mg/liter to the water to enhance the sterilization effect. All the viruses were killed after five minutes of mixing the acidic ozone water with about 430,000 viruses in the environment.

When observing the number of viruses killed in a given time, the researchers found that the acidic ozone water had a synergic effect, outperforming the sum of the individual effects of acidic water and ozone water. Part of the reason for the enhanced sterilization is that, while ozone decays over time due to impurities, the acidification of water slows the decay, prolonging the time of disinfection.

In another experiment, the researchers found that E. coli cells treated with acidic ozone water at pH 4 and an ozone concentration of 20 mg/liter destroyed the cell envelopes. Based on this observation, the scientists speculate that acidic ozone water may work by destroying the H1N1 virus envelopes, disabling their ability to establish an infection.

Well, that's good news. Perhaps this will slow the spread?

The real question is, if there was no media hype regarding H1N1 would we have seen anything more than a mild statistical deviation from the normal flu mortality rates anyway!?
