Texas woman dies due to brain-eating bacteria after using tap water
The CDC report stated that the woman had used water from her RV at a campground. The water was inadequately disinfected and contained Naegleria fowleri, a brain-eating amoeba.
The report noted that the otherwise healthy woman developed seizures and, despite receiving medical treatment, died eight days after the onset of symptoms. Laboratory testing at the CDC confirmed the presence of N. fowleri in the patient's cerebrospinal fluid.
Highlighting the importance of water quality, the CDC report stated: 'This case highlights the potential for serious health risks associated with improper use of nasal irrigation devices, as well as the importance of maintaining RV water quality and ensuring that municipal water systems adhere to regulatory standards.'

Following the incident, an epidemiologic investigation conducted by the Texas Department of State Health Services concluded that the patient had performed nasal irrigation four days before falling ill. Although the investigation could not determine the exact source of the amoeba—whether from the RV's potable water tank or the municipal water system—it confirmed that the route of exposure was tap water.
During the investigation, the CDC collected 12 environmental samples, including the patient's irrigation device, water from the RV's water heater, and water from other sources in the RV. The CDC concluded that no N. fowleri DNA or viable amoebae were detected in any of the environmental samples collected from the campsite or RV water system, despite its confirmed presence in the patient.
Naegleria fowleri is a free-living amoeba - a type of one-celled organism - that thrives in warm freshwater lakes, rivers, and hot springs. It is nicknamed the "brain-eating amoeba" because it can infect the brain and destroy brain tissue. Though infections are rare, they are often fatal.

Wolbachia transinfection: China's plan to mate lab mosquitoes with wild ones to tackle chikungunya
TIL Creatives The Chinese government has taken prevention and control measures to try to curb the spread of chikungunya, a virus that often causes fever and joint pain. The Chinese government has taken prevention and control measures to try to curb the spread of chikungunya, a virus that often causes fever and joint pain. The steps initiated by the communist regime have caused concerns among medical professionals and the people. As the chikungunya outbreak continues to engulf China, Guangdong Province reported 1,387 new chikungunya cases between August 3 and August 9, 2025, The EPOCH Times reported, citing a notice by the provincial Centers for Disease Control and Prevention (CDC). According to state media, the cumulative number of chikungunya cases as of July 29 in Foshan, Guangdong, where the first cases of the outbreak were reported on July 8, had crossed the 6,000 mark. The measures taken by the Chinese authorities amid the chikungunya outbreak include mandatory blood tests and mosquito breeding. Residents in various locations in the Guangdong Province shared on social media platforms that mandatory blood tests are being implemented for PCR testing for chikungunya, the EPOCH TIMES reported. It is different from the saliva tests for largest mosquito breeding facility in the Huangpu District of Guangzhou city, Wolbaki, was running at full capacity and releasing 5 million specially treated male mosquitoes per week, The EPOCH TIMES reported, citing Chinese state media. The step was taken in the hopes of them mating with the wild female mosquito population to produce unviable eggs in a population control technique known as Wolbachia transinfection, where the reproductive compatibility of male mosquitoes is altered by an infection with the common naturally occurring Wolbachia bacterium. Unviable eggs are eggs that, for various reasons, cannot develop into viable offspring. Wolbachia transinfection is a method where the reproductive compatibility of male mosquitoes is altered by an infection with the common naturally occurring Wolbachia bacterium.'When the [infected] male mosquitoes carrying the Wolbachia bacterium mate with wild female mosquitoes that do not carry the bacteria, the eggs produced cannot develop normally due to cytoplasmic incompatibility and cannot hatch into mosquito larvae,' Gong Juntao, the head researcher at Guangdong's Wolbaki company that produces the mosquitoes, told Chinese media, as quoted by THE EPOCH method has loopholes. For instance, if infected lab females are not separated and instead released into the wild, they can continue to successfully breed and spread disease. Chikungunya is a disease caused by a virus of the same name. The chikungunya virus was first identified in people sickened during an outbreak in Tanzania in 1952. Its name is derived from a word in the Makonde language, which means 'that which bends up,' due to the severe pain it can is transmitted by infected mosquitoes and mostly causes mild symptoms. The majority of people who get chikungunya recover without needing medical attention after one to two typically produces symptoms including fever, muscle pain, nausea, fatigue, and a rash. But in rare cases, it can cause debilitating joint pain that persists for months or even years. Patients who get severely ill often require hospitalization because of the risk of organ damage. The World Health Organization says severe cases and deaths are rare and mostly occur in babies or elderly people with underlying health is no specific treatment for chikungunya, but health workers can treat the symptoms by giving medicines to lower fevers or ease muscle pain. Two vaccines have been approved in several regions, including Britain, Brazil, Canada, and Europe. Those are mostly targeted at travelers and are not widely available in the countries most affected by chikungunya.

New variant Stratus causes spike in Covid-19 cases: What are its symptoms?
Symptoms are similar to other Omicron subvariants, including fever, chills, shortness of breath, sore throat, fatigue, headache, nausea, vomiting, muscle aches, loss of taste or smell, and diarrhoea The Chief Minister has also questioned whether the Covid vaccine might have anything to do with these deaths. Pixabay/Representational Image Several western US states are seeing sharp increases in Covid-19 activity, with the latest Centers for Disease Control and Prevention (CDC) data showing wastewater virus levels at their highest since winter. In an update released Friday, the CDC said national wastewater indicators have risen to a 'moderate' level, up from 'low' the previous week. Alaska, California, Colorado, Nevada and Utah are all classified as 'high.' 'Wastewater monitoring can detect viruses spreading from one person to another within a community earlier than clinical testing,' the CDC said, noting that elevated levels often signal increased infection risk. California's own tracking shows viral loads now surpassing last winter's peaks. STORY CONTINUES BELOW THIS AD Other metrics are climbing as well. As of Tuesday (August 12), infections were growing or likely growing in 45 states, up from 40 the previous week. New variant 'Stratus' emerging A new Covid-19 variant, XFG, nicknamed 'Stratus', has to become the third-most common strain in the US this summer. First detected in Southeast Asia in January, it remained rare in the US until May but by late June was estimated to account for up to 14 per cent of cases. Symptoms are similar to other Omicron subvariants, including fever, chills, shortness of breath, sore throat, fatigue, headache, nausea, vomiting, muscle aches, loss of taste or smell, and diarrhoea. Some patients have also reported a distinctive hoarseness or raspy voice, which could help distinguish XFG from other strains. Physician Jon LaPook told CBS in July that summer upticks in Covid-19 are 'typical' as people gather indoors to escape extreme heat. Federal vaccine contracts cut The surge comes as the US Department of Health and Human Services announced Tuesday it would end 22 federal contracts for mRNA-based vaccines, a technology credited with helping bring the pandemic under control. The move has raised questions about the future of Covid-19 vaccine development.

COVID wave is moving across USA: Health experts warn parents that children must do this
Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads FAQs Tired of too many ads? Remove Ads United States of America is witnessing a late-summer COVID wave, even as children are preparing to return to school. Fortunately, hospitalization rates remain low. The risk of severe illness and hospitalization among children younger than 1 who are infected with the coronavirus is comparable to that among adults 65 and older. That's why experts have said that a child's first exposure should be through a vaccine, rather than infection. However, this fall, it may not be possible for many parents to have a healthy child younger than age 5 immunized against COVID, as per a health experts noted that the coronavirus is still a threat, even for otherwise healthy children younger than 2. Among children ages 6 months to 2 years who were hospitalized with COVID from October 2022 to April 2024, more than half had no underlying medical conditions, according to data from the CDC, NYT News Service reported. Pfizer 's vaccine has long been available to these children under so-called emergency use authorization. But the Food and Drug Administration is considering discontinuing the authorization for that age group, according to an email sent by the Centers for Disease Control and Prevention to state and local health confirmed the possibility Monday evening and said that the company was "currently in discussions with the agency on potential paths forward." For children 5 to 11 years old, the Pfizer vaccine is expected to be approved and available, according to the CDC's email, which was reviewed by The New York July, the FDA granted full approval to Moderna's COVID vaccine for children -- but only for those who have health conditions that may put them at increased risk should they become infected. Novavax's COVID vaccine has never been available for children younger than upshot is that if the FDA does not renew Pfizer's authorization for children 6 months to 4 years, or fully approve the vaccine, healthy children in that age group will have no officially sanctioned options -- although doctors may still choose to provide the vaccine "off label."In May, Health Security Robert F. Kennedy Jr. announced that COVID vaccines would no longer be offered to healthy children or pregnant women. Kennedy has called the Pfizer and Moderna vaccines dangerous. In May 2021, in the thick of the pandemic, he filed a petition with the FDA demanding that the agency revoke authorization for the CDC, which typically makes such recommendations, later walked back the secretary's statement, saying that healthy children could get the shot if a doctor agreed that it was told the CDC it was ramping up supplies of its vaccine for the fall, according to the agency's email. But it is not approved for healthy children, and if the FDA rescinds authorization for children younger than 5, parents of healthy children will find themselves with no Nixon, a spokesperson for the Department of Health and Human Services, declined to comment on potential regulatory changes and said any reports before an official statement should be treated as "speculation."But public health experts noted that the coronavirus is still a threat, even for otherwise healthy children younger than 2. Among children ages 6 months to 2 years who were hospitalized with COVID from October 2022 to April 2024, more than half had no underlying medical conditions, according to data from the vaccines have also been shown to offer modest protection against long COVID in some children. The effects are already becoming apparent. Providers have stopped ordering last year's shot, as they often do at this time of the year. Normally by this point, there would be a clear plan for the 2025-26 season.A1. The full form of CDC is Centers for Disease Control and Prevention.A2. Full form of FDA is Food and Drug Administration.
