FDA Approves In-Home HIV Test
The FDA announced today’s decision with a press release and a warning:
The OraQuick In-Home HIV Test is designed to allow individuals to collect an oral fluid sample by swabbing the upper and lower gums inside of their mouths, then place that sample into a developer vial, and obtain test results within 20 to 40 minutes. A positive result with this test does not mean that an individual is definitely infected with HIV, but rather that additional testing should be done in a medical setting to confirm the test result. Similarly, a negative test result does not mean that an individual is definitely not infected with HIV, particularly when exposure may have been within the previous three months. The test has the potential to identify large numbers of previously undiagnosed HIV infections, especially if used by those unlikely to use standard screening methods.

United Kingdom: Drug-Resistant Gonorrhea
The British government is telling doctors that the usual course of treatment for gonorrhea is now largely useless.
- The Health Protection Agency says we may be heading to a point when the disease is incurable unless new treatments can be found. For now, doctors must stop using the usual treatment cefixime and instead use two more powerful antibiotics. One is a pill and the other a jab. The HPA say the change is necessary because of increasing resistance. [snip] As recently as 2005, no gonorrhoea bacteria with reduced susceptibility to cefixime could be found in the UK. The bacterium that causes the infection - Neisseria gonorrhoeae - has an unusual ability to adapt itself and has gained resistance, or reduced susceptibility, to a growing list of antibiotics - first penicillin itself, then tetracyclines, ciprofloxacin and now cefixime.
