US Officials Confirm Two New Avian Flu Cases As Study Suggests Virus Is Not Causing Asymptomatic Infections

The AP (7/19, Stobbe) reported, “U.S. health officials on Friday announced two more bird flu cases among farmworkers, but they also said a new study in Michigan suggested the virus is not causing silent infections in people.” In June, “the Michigan Department of Health and Human Services launched a study of workers who were around cows sickened by the bird flu.” One goal of the study “was to determine if there were people who never had any symptoms but did have evidence of past infections.” Researchers found “none of the blood testing showed antibodies that would indicate such infections, the Centers for Disease Control and Prevention reported on Friday.” The New York Times (7/20, Anthes, Weiland) reported, “In its online update, the C.D.C. noted that the results supported its approach to testing, which has focused on symptomatic people who had been in contact with sick animals.” However, “outside experts were not convinced, noting that much more data was needed.” Reuters (7/19, S K) reported the CDC “confirmed two additional cases of bird flu in Colorado poultry farm workers.” The “new cases were in poultry workers with exposure to infected poultry during depopulation and disposal activities, the CDC said on Friday.”

Summer COVID-19 Wave Spreads Across US As Biden Tests Positive For Virus

The Washington Post (7/18, A1, Nirappil, Ortega, Vozzella) reports “a summer covid wave has washed over most of the United States, bringing yet another round of gatherings turned into superspreaders.” COVID-19 “activity in wastewater reached levels considered ‘high’ or ‘very high’ in 26 states, according to the most recent data reported by the” CDC. Some other metrics “suggest the virus is rising, including the prevalence of covid diagnoses in emergency rooms and the rate of tests processed at labs coming back positive, but not to the degree of the winter surge.” Meanwhile, President “Biden has entered isolation in his Rehoboth Beach home in Delaware after testing positive with mild symptoms Wednesday, the most high-profile example of the virus’s reach.”

Blood Biomarkers Can Predict Rugby Players At Highest Risk For CTE, Other Neurological Issues, Study Finds

HealthDay (7/18, Mundell) reports a study “suggests that certain blood biomarkers could predict” rugby “players at highest risk for” chronic traumatic encephalopathy (CTE) “and other neurological issues.” The research found that “compared to athletes without high numbers of head injuries, higher levels of certain ‘serum exosomes’ were observed in the blood of retired male rugby players who’d had multiple concussions during their playing careers.” Furthermore, “levels of two blood proteins – serum t-tau and tau-p181 – were found to be elevated among the retired male rugby players compared to healthy controls.” The findings were published in the International Journal of Molecular Sciences.

Research Finds Daily Dose Of Doxycycline Prevents Some Infections With Syphilis, Gonorrhea, Chlamydia

The New York Times (7/18, Mandavilli) says “a daily dose of” doxycycline, a widely used antibiotic, “can prevent some infections with syphilis, gonorrhea and chlamydia, potentially a new solution to the escalating crisis of sexually transmitted infections, scientists reported on Thursday.” Researchers looked at gay and bisexual men who “were already taking a daily pill to treat H.I.V., and they added 100 milligrams of doxycycline each day for 48 weeks.” Researchers “found that daily doxycycline slashed the rate of syphilis infections by 79 percent, chlamydia by 92 percent and gonorrhea by 68 percent.” The findings will be presented next week at a conference of the International AIDS Society.

Mosquitoes Infecting People With Dengue At Historic Levels Across The Americas

USA Today (7/18, Cuevas) reports, “Mosquitoes are infecting people across the Americas with dengue at historic levels and U.S. travelers are bringing the potentially life-threatening virus home with them.” In South America, dengue cases “are now decreasing during cooler winter months after record numbers of people were sickened by” the disease. However, “experts warn more people will get infected across Central America, Mexico and the Caribbean as summer and hurricane season take their holds in the Northern Hemisphere.” Although “risk of local transmission in the contiguous U.S. remains low, officials are concerned about the extent to which the country will be able to harbor dengue in the years ahead.”

Blood Test May Predict Whether Patients With Glaucoma Will Continue To Lose Vision Following Treatment, Research Suggests

HealthDay (7/16, Thompson) says “an experimental blood test might be able to predict whether” patients with glaucoma “will continue to lose their vision following treatment, researchers report.” Researchers found that “a biochemical called nicotinamide adenine dinucleotide (NAD) tends to be lower in people with glaucoma compared to those without the eye disease.” Additionally, patients with glaucoma who have “lower NAD levels than others tended to lose their vision more quickly, even after receiving treatment to lower fluid pressure in the eye.” The findings were published in Nature Medicine.

Colorado Workers With Bird Flu Were Working During Extreme Heat, Under Large Fans, CDC Says

Reuters (7/16, Douglas, Steenhuysen) reports, “Colorado workers who contracted bird flu were working during extreme heat and under large fans, factors that made wearing protective equipment difficult and potentially contributed to their infections, the U.S. Centers for Disease Control and Prevention said on Tuesday.” The federal agency “had previously confirmed four cases and a fifth presumptive positive case of bird flu among Colorado farm workers who were killing and disposing of chickens that had contracted the virus.” When employees “were killing the infected chickens, it was 104 degrees Fahrenheit (40 degrees Celsius) in Colorado, and strong industrial fans made it hard for workers to keep protective gear on their faces, [CDC Principal Deputy Director Nirav] Shah said.”
