This is also confirmed by the first global meta-analysis of the Universities of Bologna and Ferrara. Bird flu: a study suggests it can be spread by inhalation
With Covid is now abundantly entered “living together” phase (they were anyway During the week from July 11 to 17, 8,942 new cases were registeredAs research into possible answers on the health front (considered in a recent bulletin published by the ministry) continues, there are many viruses that remain the focus of maximum attention.
Among the possible traps that seem more dangerous are, for example Dengue disease and the so-called “bird flu”. In this regard, they come to the forefront positive news about vaccine efficacy and safety. As for the virus H5N1Now that the species jump from birds has taken full effect, affecting many livestock, especially US farms, the first considerations how the infection is transmitted between cows.
Dengue: TAK-003 or Qdenga, effective and safe
TAK-003 or Qdenga currentlyIt is the only vaccine approved in Italy and for fighting in many European countries Against dengue. But his efficiency gives us hope. It really is more than 50% in reducing cases and has a long-term and safe effect. This is according to a study involving the universities of Bologna and Ferrara More than 20 thousand peopleeven more than a year after the last administration.
L’investigationIt is published in the journal Vaccines First in the world overall and the results showed it more than 90% of those who received both doses developed antibodies. Also reply with single dose was it’s still good: was sufficient for the development of antibodies in it more than 70% of adults and more than 90% of children and adolescents.
As highlighted by the first author of the study, Maria Elena Flacco, director of the School of Public Health Specialization at the University of Ferrara, with the results obtained safety, immunogenicity and efficacymanagement A complete vaccination cycle consisting of 2 doses may be the main means of prevention. The available vaccine may therefore be very useful for populations living in endemic areas, as well as for travelers from non-risk areas.
It takes years of research to get a vaccine
I more than 400 million annually nation infected from the Dengue virus, which is transmitted by some mosquito species and is especially widespread in the hottest regions of the planet. In Italy, as in all of Europe, it is mainly available imported travel related illness Where it is more likely to catch it, such as tropical and subtropical areas of Africa, Southeast Asia and China, India, the Middle East, Latin and Central America, Australia and various parts of the Pacific.
in Italy From January 1 to July 11, 2024 to the national arbovirus surveillance system of the Istituto Superiore di Sanità 283 confirmed cases Dengue is all related to foreign travel and affects people with an average age of 43 with no deaths.
Following the increase in cases in an increasing number of countries, this disease is at the center of a disease in us.health warning. From now on There is no effective therapy against the virus, the only strategy for prevention is a vaccine, which scientists have obtained after several years of research.
Even breathing can spread bird flu among cows
Another study from the United States Department of Agriculture (available in a preprint version on the BioRxiv platform)efficacy of avian influenza infection among cowsproves it they can become infected by inhaling virus-laden aerosols.
They came to this conclusion by infecting cows and calves A specific H5N1 strain isolated from Texas cattle exposed 4-year-old female calves to virus-laden mist at the start of the outbreak and subsequently through a mask covering the animals’ noses and mouths.
All infected animals are produced neutralizing antibodies against the virus, confirming the infection. Calves showed mild symptoms and researchers have an infectious virus isolated in the upper respiratory tract from 2 of them. The results of the study show that hundreds of animals are kept in a closed environment may be a virus so that spread through the respiratory tract.
However, it should be noted that according to experts, it would not represent a major source of diffusion, the study showed that the animals involved did not shed large amounts of the virus. So, until today the mode of transmission that caused the pandemic In US farms, it would remain largely through contaminated milk.
