A flu vaccine is needed every year for two reasons. First, a person’s immune protection from vaccination declines over time, so an annual flu vaccine is needed for optimal protection. Second, because flu viruses are constantly changing, the composition of flu vaccines is reviewed annually, and vaccines are updated to protect against the viruses that research indicates will be most common during the upcoming flu season. For the best protection, everyone 6 months and older should get vaccinated annually.

Heat stress can affect many outdoor and indoor workers. To prevent heat-related illnesses (HRI) and injuries, employers should develop and use a comprehensive heat-related illness prevention program at the workplace. In occupational settings, heat stress is the combination of the heat your body produces (metabolic heat), environmental factors (for example, temperature and humidity), and clothing and personal protective equipment (PPE). While many workers need to wear PPE for protection from workplace chemical, physical, and biological hazards, PPE can increase the risk for HRIs.

Doctors watching for more cases after mysterious cluster of brain infections strikes kids in southern Nevada
EIS officers investigated a cluster of rare and serious brain abscesses in kids in and around Las Vegas, Nevada, and doctors from other parts of the country say they may be seeing a rise in cases, too. Dr. Jessica Penney, EIS class of 2022, presented findings during the 2023 EIS conference of her investigation into the Clark County, Nevada cluster while CDC continues monitoring the situation closely. Pandemic-related social distancing, which limited children’s typical exposures to infectious diseases, is a suspected cause of an “immunity gap;” therefore potentially leading to unusual increases in childhood infections.
