In recent months the highly pathogenic H5N1 virus has been spreading through US cattle herds for the first time ever. The cow-to-cow transmission is the latest escalation in a global outbreak that began when the virus reemerged in Europe in 2020.

CNN —The bird flu spreading through cattle in the United States is an “enormous concern” the chief scientist of the World Health Organization said Thursday as he called for more tracking and preparation for the virus. So far, there is no evidence that the highly pathogenic H5N1 flu virus can spread from person to person. Though H5N1 doesn’t spread from person to person, humans can catch it when they’re exposed to infected animals. They are only the second documented case of human H5N1 in the United States. The US Centers for Disease Control and Prevention says that while the current risk to public health from H5N1 is low, it is monitoring the situation carefully.

☆ WHO clarifies what counts as a pathogen that can spread through the air

“Airborne transmission” refers to when infectious respiratory particles expel into the air, such as from coughing or sneezing, and enter the respiratory tract of another person who inhales them, according to WHO. The subcategory “direct deposition” refers to when infectious respiratory particles expel into the air and directly land on another person’s mouth, nose or eyes, potentially causing infection. “Public health agencies were hesitant to use the word ‘airborne’ because of differences in understanding among experts about what it meant. When I say ‘aerosol’, when I say ‘through the air’, it doesn’t matter whether I’m an engineer, a clinician, a nurse, a public health person. ‘There were many failures’During the pandemic, various terms were used in different ways to describe how the coronavirus could spread, causing much confusion – terms like airborne, airborne transmission or aerosol transmission.

By Jennifer Rigby(Reuters) - A pill for dengue fever developed by Johnson & Johnson appeared to protect against a form of the virus in a handful of patients in a small human challenge trial in the United States, according to data presented by the company on Friday. In human challenge trials, researchers intentionally expose healthy volunteers to a pathogen to test a vaccine or treatment, or better understand the disease they cause. Dengue fever, while often asymptomatic, is also known as “break bone fever” for the severity of the joint pain and spasms that some patients experience. In the trial done with Johns Hopkins Bloomberg School of Public Health, 10 volunteers were given a high dose of the J&J pill five days before being injected with a type of dengue. The five people in a placebo group, who were also injected with dengue, all showed detectable virus when tested.

By Jennifer RigbyLONDON (Reuters) - Dengue fever will become a major threat in the southern United States, southern Europe and new parts of Africa this decade, the WHO's chief scientist said, as warmer temperatures create the conditions for the mosquitoes carrying the infection to spread. Many cases go unrecorded, but in 2022 4.2 million cases were reported worldwide and public health officials have warned that near-record levels of transmission are expected this year. Earlier this week, the WHO recommended Takeda Pharmaceuticals' Qdenga vaccine for children aged 6 to 16 in areas where the infection is a significant public health problem. Qdenga is also approved by the EU regulator, but Takeda withdrew its application in the United States earlier this year, citing data collection issues. Dengue is spread by infected Aedes aegypti mosquitoes, which behave differently to the malaria-carrying kind.
