United States: Travelers express concern about their health safety while visiting regions with current measles outbreaks because both American and international territories have seen rising measles case numbers. 

The Centers for Disease Control and Prevention (CDC) reports that 483 confirmed measles cases have emerged across more than a dozen states, including California, Florida, Ohio, and Vermont, beginning this year, and most of these cases originated from Texas, New Mexico, and Kansas. 

Statistics indicate that existing case numbers surpass every case reported in the year 2024.

Accumulated measles cases from the beginning of this year reached 483; the CDC stated that 97% happened to unvaccinated individuals or people whose vaccination status remained undetermined, as USA Today reported. 

The region of Europe experienced its most significant measles outbreak in 25 years, according to recent data from the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF). 

Here’s what travelers should know  

When someone who is infected coughs or sneezes, Measles shows “highly contagious” characteristics, according to the CDC. 

The illness spreads through the air people breathe in after contact with microbes on surfaces, which remain infectious for two hours, and also by transferring liquids from contaminated surfaces to their eyes, mouths, and noses. 

Records from the health agency show the international journey as an origin point for measles victims. 

According to the CDC, “The disease is brought into the United States by unvaccinated people who get infected in other countries,” USA Today reported. 

“Typically, 2 out of 3 of these unvaccinated travelers are Americans. They can spread measles to other people who are not protected against measles, which sometimes leads to outbreaks,” it added. 

The CDC website states that unvaccinated people transmit the disease into American territory after getting infected in other countries. 

Furthermore, Dr. Stephen S. Morse, a professor of epidemiology at Columbia University’s Mailman School of Public Health, mentioned that whether or not travelers should be concerned depends on if “they already have some, what the CDC would call presumptive evidence of immunity … or if they’re going to an area where there is a fairly high measles risk.” 

United States: Government authorities show heightened suspicion about disease transmission through mosquitoes because meteorological factors have triggered swift population expansion among mosquito populations. 

The state experienced its highest number of dengue mosquito-transmitted diseases through mosquito surveillance conducted by travel officials.

The current projections show that mosquito numbers will surpass previous records for another consecutive year. 

According to Steve Harrison, manager of Orange County Mosquito Control, “It would be surprising if we aren’t at the same level that we were last year,” US News reported. 

“You could assume that going into the subsequent year, you’re going to see a little more activity because it rarely drops off to extreme levels from year to year. It’s normally a gradual decline,” Harrison stated. 

Dengue infection, which people commonly call “bone break fever,” leads to symptoms including high temperature with accompanying muscle and joint discomfort and nausea together with eye discomfort. 

The Mayo Clinic reports that serious dengue disease manifestations may include stomach distress and respiratory trouble, along with bleeding within the gums or nasal cavity. 

Lately, the Florida Department of Health has recorded 911 travel-related cases based on their data report. The local reports numbered 85, while the travel-related cases reached 911. 

The transmission of dengue virus through person-to-person contact creates the main concern about travel-related dengue cases. 

The transportation of dengue fever by Florida residents occurs when they visit countries with endemic dengue cases, like Cuba, before returning home with this viral infection. 

A Florida resident becomes vulnerable to mosquito infection after a traveling person gets bitten by a Florida mosquito. Repeated viral infections could lead to an endemic state of the virus in Florida. 

The virus increases its propagation potential when temperature rises and rainfall increases since these conditions create favorable mosquito breeding areas. 

Harrison predicted, based on early summer weather projections, that mosquitoes would find enough suitable conditions to survive this season. 

“Unfortunately, looking at the trends, one would assume that we’re probably going to see levels that we did last year because people are still traveling as much,” Harrison added. 

The state of Florida remains free from local dengue cases during this current year. The total travel cases throughout week 12 of the year amount to 49 confirmed cases, according to public records. 

The clinical records show seven Central Florida patients, with four individuals infected in Orange County. 

United States: The total annual carbon dioxide emissions from unnecessary imaging scans for Medicare patients reaches 129 metric kilotons, which could operate a community of 70,000 people for one year. 

Unnecessary Imaging Scans 

As per the researcher Elizabeth Rula, executive director of the Harvey L. Neiman Health Policy Institute in Reston, VA, “Our analysis demonstrates the potential to meaningfully reduce our carbon footprint by decreasing unnecessary imaging orders,” US News reported. 

Research analysis was conducted to examine image scanning data from traditional Medicare programs that supported around 30 million patients from 2017 to 2021. 

Previous research indicates that around 26% of imaging tests given to Medicare beneficiaries should not have been prescribed. 

Carbon Emissions 

Researchers conducted a study review to evaluate the number of wasteful imaging procedures while determining related carbon dioxide emission levels. 

All imaging scans produced immense carbon dioxide emissions where MRIs reached 136 kilotons, CT scans reached 178 kilotons, X-rays yielded 46 kilotons, and ultrasounds created 23 kilotons, according to study results. 

As per the lead researcher, Dr. Gregory Cavanagh, a resident at Lahey Hospital & Medical Center, the high-end estimates “also included the energy required when the scanners are in standby mode or in production phase between scans,” US News reported. 

Research findings indicate that eliminating unnecessary imaging scans would decrease carbon dioxide emissions to 129 kilotons. The research team found that superfluous CT scans produced fifty percent of these excessive emissions, alongside superfluous MRI procedures accounting for another quarter. 

Additionally, “Emissions are likely to continue to increase given sustained increases in overall imaging volumes over the past decade, and the potential for further increases related to climate-change related exposures and events,” as the researcher Dr. Julia Schoen, who is a clinical assistant professor at the University of Michigan Health in Ann Arbor, MI stated.
