After more than 2,000 cases of reported hepatitis A cases in Florida this year, state Surgeon General Scott Rivkees declared a public health emergency Thursday.

“I am declaring this Public Health Emergency as a proactive step to appropriately alert the public to this serious illness and prevent further spread of Hepatitis A in our state,” Rivkees said in a prepared statement.

Rivkees encouraged people to be vaccinated against the virus, which is spread through oral injection or fecal matter.

South Florida researchers believe they're one step closer to developing a more effective vaccine against HIV, after overcoming a virus that infects monkeys.

Nicknamed the "Death Star," SIVmac239 is a particularly resilient immunodeficiency virus that features the same obstacles that have vexed HIV vaccine researchers over the years: the outer layers around the viruses mutate quickly. It's like the immune system is trying to track a shapeshifter—a defense against the viruses works, and then it doesn't.

Hundreds of students and faculty at two universities in Los Angeles have been asked to stay home unless they can prove that they've been vaccinated against measles.

The LA campuses of the University of California and California State University imposed the quarantine after they became aware of people infected with measles who had potentially exposed hundreds. At UCLA, a student exposed at least 500 people earlier this month; at Cal State, someone with measles went to a library and encountered hundreds.

Flu symptoms can be more severe when you're pregnant, landing women in the hospital, threatening their lives and even leading to preterm birth or miscarriage. The virus is a risk to the woman and the baby.

So, it's particularly important that people who are pregnant get the flu vaccine. And it's also important that the effects of those vaccines be studied in pregnant women.

A campaign is currently underway in Florida to educate parents about a childhood vaccine that can prevent cancers associated with the sexually-transmitted human papillomavirus, or HPV, in adulthood.
