Drug-Resistant Infections: A New Epidemic, And What You Can Do To Help

Are you aware that colds, flu, most sore throats and bronchitis are caused by viruses? Did you know that antibiotics do not help fight viruses and that using them for viral infections only decreases their effectiveness overall?

Millions of Americans take antibiotics each year to fight illness, trusting they'll work. However, the pathogens are fighting back. Within the past couple of years, new drug-resistant patterns have emerged, and resistance to common antibiotics has increased.

Discovery Whilst Studying Why Measles Spreads So Quickly Has Implications For Ovarian, Breast And Lung Cancers

Mayo Clinic researchers have discovered why measles, perhaps the most contagious viral disease in the world, spreads so quickly. The virus emerges in the trachea of its host, provoking a cough that fills the air with particles ready to infect the next host. The findings may also help in the fight against ovarian, breast and lung cancers.

The findings, published online in the journal Nature, give researchers insight into why some respiratory viruses spread more quickly and easily than others: They found the measles virus uses a protein (called nectin-4) in the host to infect and then leave from the strategic location of the throat.

Bacterial Protection From Allergy

Oversensitivity diseases, or allergies, now affect 25 per cent of the population of Denmark. The figure has been on the increase in recent decades and now researchers at the Dansk BørneAstma Center [COPSAC, Copenhagen Prospective Studies on Asthma in Childhood], University of Copenhagen, are at last able to partly explain the reasons.
