The overuse of antibiotics has led to an increase in antibiotic resistance, and inappropriate prescribing and antibiotic misuse are major contributors to this problem. In one study conducted between 2010 and 2011, researchers noted that as many as 34 million prescriptions for antibiotics were written for illnesses like the flu, upper respiratory infections, and bronchitis, all of which typically don’t require the use of antibiotics. Although antibiotic use is necessary for some infections, like pneumonia and urinary tract infections, many people will often get better in a reasonable amount of time by simply treating symptoms.
Doctors recently discovered a gene in E. coli bacteria that makes it resistant to an antibiotic that is typically used when other drugs fail. This new finding suggests that effectiveness of last-resort antibiotics is at risk. As more bacteria evolve to “outsmart” antibiotics, scientists are increasingly concerned about infections caused by “superbugs” that cannot be treated with existing antibiotics.
For years, many kids could skip the traditional flu “shot” — along with the tears — and still be protected by the nasal spray vaccine also known as the LAIV (live attenuated influenza vaccine). But not this year. Studies now show that the nasal vaccine is quite ineffective, and pediatricians are starting to change their flu recommendations from a nose squirt to a shot.
Just a few months ago, public health experts were confident that there would be minimal spread of Zika virus into the United States. But as they’ve continued to study Zika and catalog its effects on countries around the world, they’re discovering that it might be scarier than they initially thought. We’ve summarized the latest findings on Zika and included tips to help you ward it off.
The development of vaccines for many once-fatal illnesses has saved the lives of hundreds of thousands of children in the United States. While some parents may have concerns about the side effects of a vaccine, the decision not to vaccinate a child extends the risk of illness to the larger community.
If you’re planning an escape from the dreary winter weather, and you’re pregnant or trying to get pregnant, you may want to plan your destination carefully. There’s still a lot we don’t know about Zika virus — which is now widespread in several favorite tropical destinations, such as the Caribbean — and its potential pregnancy-related complications. Until we know more, it’s better to be safe and follow the precautions we’ve listed here.
Shingles, an itchy and painful rash that occurs when the chickenpox virus reactivates in your body, shouldn’t be written off as just a nuisance. If it’s not treated promptly with an antiviral drug, it can cause a host of serious long-term complications. Fortunately, there’s a vaccine that can slash your risk of shingles by half, and another, even more effective one in the pipeline.
Many people still think the color or consistency of nasal discharge determines whether you have a sinus infection. The truth is that anything that irritates the nose’s delicate lining — whether a virus, bacterium, or allergen — can result in any color or consistency of discharge. In fact, viruses are the most common cause of sinus infections, meaning you shouldn’t run to your doctor based on your mucus color alone.
Zika, a virus that was almost unknown just a short time ago, is now certain to spread to almost every country in the Americas. But why have the U.S. and other countries become more vulnerable to the threat of exotic pathogens? There currently aren’t enough data to make any solid connections, but many experts agree that the rise of global trade and travel, climate change, and ecosystem changes are all major factors.
Zika, a formerly rare and obscure virus, has recently spread throughout the Pacific islands and the Americas. Although Zika virus rarely makes people seriously ill, it’s been implicated in a huge rise in the number of birth defects in babies born to mothers who’ve had Zika. Although its impact in the U.S. is expected to be much less severe than in warmer climates, we’ve listed some tips to reduce your exposure to the type of mosquito that carries Zika.
