First measles case confirmed in Bell County

BELL COUNTY, Texas (FOX 44) – The Bell County Public Health District (BCPH) has announced its first confirmed case of measles. BCPH says the resident is an unvaccinated adult. The organization is investigating this case for any further information or potential community exposures, including identifying the status of recent international or domestic travel. According to BCPH, measles is a highly contagious viral infection which can cause life-threatening illness or death, especially in babies and children. It is spread through the air or close contact. Measles is a vaccine preventable disease with a 97 percent effectiveness rate when fully vaccinated. BCPH says measles spreads through the air when an infected person breathes, coughs, sneezes, or talks. A person can become infected by breathing contaminated air or touching contaminated surfaces then touching the eyes, nose, or mouth. Those with measles are contagious about four days before their rash starts to four days after it appears. The virus can stay in the air and on surfaces for up to two hours after the infected person has left the area. According to BCPH, measles can cause serious illness in all age groups. However, certain groups are more likely to suffer complications such as pneumonia or brain swelling from measles. The groups of people at highest risk for measles complications include all individuals who are not vaccinated or have not previously had a measles infection; children younger than five years old; pregnant women; and people with weakened immune systems coming from leukemia or HIV infection. The first measles symptoms typically appear one to two weeks after being exposed to measles. They include mild to moderate fever, cough, runny nose, and/or red, watery eyes. Two to three days after symptoms start, small, white spots appear inside the mouth, referred to as Koplik spots. Three to five days after symptoms start a blotchy red, flat and raised rash that starts on the face and spreads to the rest of the body and a high fever (may spike to over 104 degrees F) begins. BCPH says to seek emergency care immediately if these symptoms appear, including a hard time breathing or breathing faster than normal, severe cough; signs of dehydration (dry nose and mouth, urinating less than usual); or seizures, confusion, decreased alertness, or severe weakness. For young children, seek help immediately if they have a blue color around the mouth, crying without making tears, unusually low energy, or severe appetite loss. BCPH says that if you develop symptoms and suspect you may have measles: · Isolate yourself and call a healthcare provider before visiting an emergency department, urgent care, or clinic so they can prepare for your arrival. According to BCPH, the most effective way to prevent measles infection and the spread of disease is through vaccination. The MMR (measles, mumps, and rubella) vaccine is safe, effective, and recommended for: · Children: Two doses – the first given at 12-15 months and the second at 4-6 years old. The second dose can be given as early as four weeks after the first dose, regardless of age. You should speak to your child's pediatrician for more information about recommended immunizations. · Adults: Anyone who has not received two doses of the MMR vaccine or has not previously had measles. · Talk to your healthcare provider before travelling internationally. Measles is found around the world. BCPH says to talk to your healthcare provider about your vaccination status and where to get the MMR vaccine. Bell County Public Health provides the MMR vaccine to people who meet the eligibility criteria for the Texas Vaccines for Children Program.

Lawrence O'Donnell Chokes Up When Detailing Harrowing Impact Of USAID Cuts

MSNBC's Lawrence O'Donnell fought back tears on air as he attacked 'soulless, mindless' President Donald Trump and Elon Musk for slashing funding that has led to children dying. On Monday's 'The Last Word,' O'Donnell cited a New York Times column that explores the impact of the Trump administration's demolition of the U.S. Agency for International Development, an organization that in 2023 disbursed more than $43 billion for humanitarian aid, economic development and health programs around the world. The piece, by columnist Nicholas Kristof, referenced Evan Anzoo, a 5-year-old boy from South Sudan born with HIV. He was 'a child as precious as yours or mine,' Kristof wrote. The orphan was being kept alive by medicines that cost less than 12 cents per day, Kristof reported, funded by the President's Emergency Plan for AIDS Relief. PEPFAR has been credited with saving more than 25 million lives since being launched by President George W. Bush. But PEPFAR has been a victim of Trump's deep cuts to overseas aid. By early March, Secretary of State Marco Rubio, who led the purge of the six-decade-old agency, wrote on social media that 83% of USAID programs had been cut. O'Donnell noted that Rubio had told Congress that 'no children are dying on my watch' as a result of the cuts. But Kristof suggested otherwise, reporting that Evan's condition weakened and he died from an opportunistic infection after his medications were cut. 'Evan died on [Rubio's] watch,' said O'Donnell, who soon started to choke up. 'Evans of all ages are dying on Marco Rubio's watch, and no one is counting. And so we don't know as of tonight whether it's tens of thousands or hundreds of thousands of Evans, but we know it will be.' O'Donnell moved on to a New York Times column headlined 'Elon Musk's Legacy is Disease, Starvation and Death,' which cites Boston University research detailing how Musk's cuts to USAID's budget have led to an estimated 300,000 deaths, most of whom are children. O'Donnell quoted a line from columnist Michelle Goldberg that argues, 'If there were justice in the world, Musk would never be able to repair his reputation, at least not without devoting the bulk of his fortune to easing the misery he's engendered.' The anchor then went on to compare Musk's butchering of the federal government with the humanitarian efforts of fellow billionaire Bill Gates, who has 'has devoted his life and his billions' to saving children in Africa. O'Donnell said this means Gates' verdict on the current richest person in the world is 'so important and powerful.' 'Bill Gates, the former richest person in the world, said, 'the picture of the world's richest man killing the world's poorest children is not a pretty one,'' continued O'Donnell. He added, 'And the picture of the richest person in the world carrying around his drug box of ecstasy, Adderall, psychedelic mushrooms and then taking life-saving drugs away from the poorest people in the world is a picture only Donald Trump could have created.' O'Donnell ended with a brutal assessment of Musk and Trump as 'soulless, mindless entities.' Watch the attack on the Trump administration below. I Am A USAID Worker Who Lost My Job. Here's What Trump And Musk Aren't Telling You About The Cuts.
