Science Magazine – September 29, 2023: This special issue examines the threats to human health and how they can be mitigated.

AN UNHEALTHY CLIMATE

Introducing a special issue of Science

Earth scientists often call climate change a “great global experiment,” which humanity is heedlessly performing as we pump greenhouse gases into the atmosphere. The dire consequences are already becoming clear—not just for the workings of the planet, but for our own health. Over the next few days, the stories in this special package will explore the threats, and how we can minimize them.

Will flu outbreaks ease in a warming world?

From cold viruses to influenza to respiratory syncytial virus, viruses that spread through the air cause billions of infections each year. That makes it important to understand how they will respond to climate change. But little is known so far, except that different viruses will react differently. Measles, for instance, spreads efficiently in all climates, suggesting global warming will make little difference to its transmission.

Massive mosquito factory in Brazil aims to halt dengue

Facility will produce up to five billion bacteria-infected mosquitoes per year

The non-profit World Mosquito Program (WMP) has announced that it will release modified mosquitoes in many of Brazil’s urban areas over the next 10 years, with the aim of protecting up to 70 million people from diseases such as dengue. Researchers have tested the release of this type of mosquito — which carries a Wolbachia bacterium that stops the insect from transmitting viruses — in select cities in countries such as Australia, Brazil, Colombia, Indonesia and Vietnam. But this will be the first time that the technology is dispersed nationwide.

Health: Why Are Flu, RSV And Strep Surging In 2022?

Daniela Hernandez | WSJ – Getting the flu can increase the risk of getting a second infection, including strep throat. WSJ’S Daniela Hernandez explains the science behind that, plus what it means for the rest of the winter and how we can protect ourselves so the tripledemic doesn’t get worse.

Top New Health Podcasts: ‘Flu Vaccine Season’ (BMJ)

With the annual flu season looming, GPs are anticipating a frenzy of vaccinations, perhaps more so than ever this year. As so many ‘flu and respiratory viruses circulate every year, and as the ‘flu vaccine is for one strain of influenza only, is the vaccine worth getting, and what are the risks associated with vaccinating vs. not vaccinating? 

 In this week’s episode, we discuss the high vaccine uptake in New Zealand, and the role that social distancing for COVID-19 may have played in their low numbers of seasonal flu. We also talk about whether or not the message we give to patients about the benefits and risks of vaccination is transparent enough, and how we might communicate better with them to allow them to make an informed decision. We feel pressure to increase vaccination rates, because we believe we are protecting people, but does the evidence support that?

Our guests: Nikki Turner is the director of the Immunisation Advisory Centre (IMAC) at the university of Auckland. She is an academic general practitioner, and a professor at the university. Jeff Kwong is a professor at the University of Toronto, and the interim director of the Centre for Vaccine Preventable Diseases at the university’s Dalla Lana School of Public Health. Newest Oldest Longest Shortest Random 

Importance Of Vaccines: Flu Hospitalizations Can Result In Sudden Heart Conditions (Infographic)

CENTERS FOR DISEASE CONTROL & PREVENTION (August 25, 2020) – A CDC study published today that looked at more than 80,000 U.S. adults hospitalized with flu over eight flu seasons (2010-11 through 2017-18) found that sudden, serious heart complications were common and occurred in one out of every eight patients (~12% of patients).

The study looked at a range of sudden heart complications called “acute cardiac events” that resulted in the following:

  • damage to the heart muscle,
  • inflammation of the heart muscle,
  • fluid or inflammation of the sac surrounding the heart, or
  • weakening of the pumping function of the heart.

The most common acute cardiac events reported in the study were acute heart failure and acute ischemic heart disease. Acute heart failure is the sudden inability of the heart to pump enough blood to meet the body’s demands, while acute ischemic heart disease is a term that describes heart problems caused by narrowed or blocked heart arteries.

Health: Diseases Rise And Fall With The Seasons – Will Coronavirus? (Video)

Scientists and doctors have observed for thousands of years that some diseases, like polio and influenza, rise and fall with the seasons. But why? Ongoing research in animals and humans suggests a variety of causes, including changes in the environment (like pH, temperature, and humidity) and even seasonal and daily changes to our own immune systems. Figuring out those answers could one day make all the difference in minimizing the impact of infectious disease outbreaks—such as COVID-19.
