Over-the-counter diagnostic tests for Chlamydia trachomatis, Neisseria gonorrhoeae, and pathogens associated with upper respiratory tract infections such as influenza and Group A Streptococcus may soon gain approval; however, making these tests immediately available to the public would not be without challenges.

The World Health Organization credits contraception with preventing pregnancy-related health risks in women, reducing adolescent pregnancies, and lowering infant mortality rates. What researchers are now discovering is that hormonal contraceptives containing progesterone may also protect women against influenza infections and repair lung damage caused by inflammation.

We hear a lot about influenza types A and B every year when flu season approaches, and occasionally about the less severe type C. Now researchers have identified a newly recognized form of the virus—influenza D.

A new study has shown that infected wild house mice will disengage from their social groups, resulting in a decreased potential for disease transmission; these findings can be applied to improve models used to predict transmission of infectious diseases spread by social contact, such as Ebola and influenza.

According to the new study, the antibacterial response of white blood cells to the flu virus fails to target the S. aureus bacteria and instead causes inflammatory injury to the lungs and damage to surrounding tissue, creating a higher susceptibility to secondary bacterial infections such as MRSA pneumonia.
