  Recently, Georgia was officially certified malaria-free by the World Health Organization (WHO). This achievement marks milestone for the country and the WHO European region. Georgia joins 45 other countries and one territory that have reached this status. The certification reflects decades of effort and investment in malaria control and elimination. Historical Context of Malaria in Georgia Malaria has affected Georgia for centuries. Before systematic control began in the early 1900s, three malaria parasite species were endemic – Plasmodium falciparum, Plasmodium malariae, and Plasmodium vivax. After World War II, Georgia initiated an extensive malaria elimination programme. This included the use of new medicines, insecticide spraying, and improved entomological surveillance. Key Milestones in Malaria Elimination Georgia successfully interrupted the transmission of Plasmodium falciparum by 1953. Plasmodium malariae was eliminated by 1960, followed by Plasmodium vivax in 1970. Alt...

  Recently, researchers from Banaras Hindu University identified a new species of phytopathogenic fungi named *Epicoccum indicum*. This discovery is linked to an emerging leaf spot disease affecting *Chrysopogon zizanioides*, commonly known as vetiver or khus. This discovery marks the importance of understanding plant diseases and their impacts on agriculture and medicinal plants . Identification Process *Epicoccum indicum* was identified through a combination of morpho-cultural characteristics and multigene molecular phylogenetic analyses. The phylogenetic study showed that this species forms a distinct clade, differentiating it from related species. This classification was crucial for recognising it as a new species. Importance of Vetiver *Chrysopogon zizanioides* is valued for its medicinal properties. It is used in traditional medicine for treating pain, inflammation, and infections. The discovery of *Epicoccum indicum* poses a risk to this important plant, making early dete...

  Nutritional support for tuberculosis (TB) patients and their household contacts has emerged as important factor in improving treatment outcomes. Recent findings from the RATIONS trial conducted in Jharkhand between August 2019 and August 2022 highlight the impact of nutritional interventions. The trial involved 2,800 pulmonary TB patients and over 10,000 household contacts. It demonstrated that providing nutritional support reduced new pulmonary TB cases by 48% and decreased deaths among severely underweight individuals. Key Findings from the RATIONS Trial The RATIONS trial revealed that nutritional support not only benefited TB patients but also impacted their household contacts. The data showed a marked reduction in new cases and mortality rates. For those under 35 kg, the death rate was only 7%. This indicates that nutritional interventions can enhance the overall health of both patients and their families. Economic Modelling Study A recent modelling study estimated the broad...

  Recent studies have revealed alarming vital information about the effects of microplastics on brain function. Research published in *Science Advances* indicates that microplastics may obstruct blood circulation, leading to impaired cognitive abilities. These findings stem from experiments conducted on mice, denoting the urgent need to understand the implications for human health. What Are Microplastics? Microplastics are plastic particles smaller than 5 millimetres. They originate from the degradation of larger plastic items and from manufactured plastic pellets. These particles are ubiquitous, found in oceans, soil, and even in remote regions like Antarctic ice . Microplastics can enter the human body through various pathways, including ingestion and inhalation. Mechanisms of Impact on the Brain The study used advanced imaging techniques to observe microplastics in the mouse brain. Researchers tracked the movement of these particles in real-time. They found microplastics lodged...

  Recently, Pune has reported increase in Guillain-Barré Syndrome (GBS) cases, with 59 individuals diagnosed, including 12 requiring ventilator support. The Maharashtra health department is investigating this sudden rise. Health officials indicate that GBS can occur after infections, but it does not lead to widespread outbreaks. About Guillain-Barré Syndrome GBS is an autoimmune condition where the immune system mistakenly attacks peripheral nerves. This results in symptoms like weakness, numbness, and in severe cases, paralysis. The exact cause remains unclear, but infections often precede the onset of GBS symptoms. Types of Guillain-Barré Syndrome GBS encompasses several forms. The most common is Acute Inflammatory Demyelinating Polyradiculoneuropathy (AIDP), primarily seen in North America and Europe. Other types include Miller Fisher Syndrome (MFS), characterised by eye-related paralysis, and Acute Motor Axonal Neuropathy (AMAN), prevalent in certain regions like China and Japa...

  The World Economic Forum (WEF) has released a report denoting the economic potential of addressing women’s health issues. Titled “Blueprint to Close the Women’s Health Gap,” the report reveals that improving women’s health could contribute an estimated $400 billion to global GDP by 2040. It identifies nine critical health conditions impacting women’s lives and puts stress on the need for targeted research and investment. Women’s Health Disparities Women experience 25% more years of poor health compared to men. This disparity is largely due to insufficient research and funding focused on women-specific health conditions. The report indicates that women are often overlooked in clinical trials, particularly in areas like ischemic heart disease and migraine , where only 10% include sex-specific data. Key Health Conditions Identified The report categorises nine health conditions into two groups – lifespan and health span conditions. Lifespan conditions include maternal hypertensive d...

  In early 2025, a study revealed mutations in the H5N1 avian influenza strain isolated from a human in Texas . This discovery raised alarms about the potential for the virus to evolve and pose a greater threat to human health. The research brought into light the strain’s unique genetic changes compared to those found in cattle, indicating a worrying trend in the virus’s adaptability. Recent Findings A study published on January 8, 2025, identified nine unique mutations in the H5N1 strain from a human patient. These mutations enhance the virus’s ability to replicate in human cells and increase its virulence. Impact on Agriculture Since 2024, clade 2.3.4.4b of H5N1 has affected around 928 dairy herds in the United States. Millions of birds have died due to the outbreak, denoting the virus’s widespread impact on agriculture. Human Infection Case The Texas case involved a dairy farm worker who developed symptoms after contact with infected milk. This incident puts stress on the zoono...
