Human Civilization is Losing the War Against Superbugs

(NaturalNews) The steady medical advance against viruses and bacteria that many experts were trumpeting in the early days of vaccines and antibiotics seems to have stalled, if not reversed. The ongoing emergence of new and increasingly drug-resistant diseases is now causing many to question whether the war against microbes is one that can ever be won.

"It is a war of attrition," said David Livermore of the United Kingdom's Health Protection Agency. "There have been points where we have been advancing, and points when we have had to beat a retreat. If we were having this conversation 20 years ago, for instance, we would be celebrating the vaccine for bacterial meningitis."

The news these days contains less of celebration and more of alarm. Even with H1N1 swine flu now appearing less dangerous than originally thought and infection rates of the superbug Methicillin-resistant Staphylococcus aureus (MRSA) falling in the United Kingdom, widespread antibiotic use and a globalized world have made the processes of pathogen evolution and spread faster than ever before.

The threat from the highly lethal H5N1 bird flu - a mere mutation away from a highly contagious form - has not abated, and other infectious threats thought long vanquished continue to rear their heads. China, for example, is currently battling an outbreak of pneumonic plague caused by Yersina pestis, the same bacterium that wiped out a third of Europe's population as the Black Plague. Meanwhile, longer lifespans have encouraged the emergence of suberbugs such as Clostridium difficile, which preferentially targets elderly patients who have already been treated with antibiotics.

"Sensible prescribing is part of the answer, but we also need new antibiotics," Livermore said. "It's not one of the most attractive areas for pharmaceutical companies as people don't take them for very long, unlike treatments for heart disease or cancer."

"We will always be at war with microbes," said Primrose Freestone of the University of Leicester. "Their genetic promiscuity is impressive."

The War on Independent Media Has Begun

A coordinated censorship attack is being waged against the entire independent media by Google, YouTube and Facebook. After we were banned by Google for nearly a week, now Facebook is deliberately blocking the sharing of our stories to further censor our important reporting for human freedom and medical choice. Soon, the only way we will be able to reach you is via email, and Google is sometimes blocking our email delivery to gmail users.

Enter your email address below to subscribe to our email announcement list (but don't use gmail). Your privacy is protected and you can unsubscribe at any time. If you don't join our email list, you may never see our valuable content again via Facebook, Google or YouTube. CENSORSHIP has now reached EXTREME levels across the 'net. The truth is being suffocated. Subscribe now if you want to escape the delusional bubble of false reality being pushed by Google and Facebook.
