Zoonotic diseases can spread from animals, including the ones we consume or keep as pets, including cats. Why are we talking about cats today? It is because of the increasing numbers of bird flu in the United States, cats of all shapes and sizes have come down with bird flu.

Bird flu was seen in poultry, where chickens have been affected, and even cows too. Why is it a concern for cats? This is because barn cats drink raw milk. In recent days, 20 wild cats at a Washington State animal sanctuary that ate infected birds and other reports of indoor cats dying from eating contaminated food have come out.

Why do cats get bird flu?

One of the leading causes is that unlike dogs, cats hunt for smaller prey, which includes birds and mice, carriers of bird flu. Dr Michael Bailey, the president-elect of the American Veterinary Medical Association (AVMA), in a guidance released for cat owners noted that by their very nature, cats have more "opportunity" to ger infected with bird flu.

“We don't know if the cats are more susceptible than anybody else,” he said. “It's just the fact they're exposed to higher viral burdens because of where they go.”

Reports say that domestic cats have been bird flu virus carrier since 2004. Kristen Coleman, an assistant professor at the University of Maryland School of Public Health told a media outlet that before, about half of cats died, and now with the spreading of the bird flu even in cows, about 90% of them seem to be dying. Coleman has also been tracking the deaths. She has also shared 4 main tips to protect pets from bird flu which includes:

• Do not touch or allow pets to touch sick or dead animals or animal dropping
• Do not consume, or feed your pet, raw meat or milk
• Keep a close watch on free-roaming outdoor pets
• Immediately report rabies-like symptoms to a veterinarian

Are there symptoms of bird flu in cats one should look out for?

As per AVMA, pet owners must look out for signs like:

• Loss of appetite
• Lethargy
• Fever

Bird flu infection can also progress with neurologic signs, which includes:

• Tremors
• Seizures
• Not being coordinated
• Blindness

Cats may also suffer from:

• Severe depression
• Discharge from their eyes or nose
• Respiratory symptoms which includes rapid breathing, shortness of breath, and sneezing or coughing

Are humans at threat?

Sick animals may also be able to transmit influenza virus to humans through their saliva, excretion and other bodily fluids. People can also get infected by breathing in the virus or by touching something that has virus on it and then touching their eyes, mouth, or nose.

If you think your cat might have bird flu—or any other infectious disease—try to limit their contact with other pets and people in your household, especially those with weakened immune systems, until you get advice from a veterinarian, as recommended by the AVMA. While the chances of cats transmitting H5N1 to humans are extremely low, they aren’t zero.

According to CDC guidance, keep an eye on yourself and your family for flu-like symptoms and reach out to a healthcare provider if needed. Be sure to wash your hands thoroughly after handling your cat or cleaning their litter box and bedding.

With advancements in medical technology, hip replacement surgery has evolved significantly over the years. One of the most promising innovations in this field is the Direct Anterior Approach (DAA) Total Hip Replacement, a modern technique that offers patients a safer procedure, reduced pain, and faster recovery.

Unlike traditional hip replacement surgeries, the DAA technique allows surgeons to access the hip joint from the front through a small incision. The biggest advantage of this approach is that muscles are not cut during the surgery. Instead, they are gently separated, which helps minimize tissue damage and reduces post-operative pain considerably.

This muscle-sparing approach has transformed patient recovery experiences. Most patients are able to stand and walk on the same day of surgery, and hospital stays are generally shorter. Recovery is smoother, allowing individuals to return to their normal routine within three to four weeks in most cases.

The DAA technique is especially beneficial for patients suffering from chronic hip pain, restricted movement, or severe joint damage. Common conditions that may require hip replacement include osteoarthritis, avascular necrosis (AVN), rheumatoid arthritis, old hip fractures, and long-standing degenerative joint conditions. When medications, physiotherapy, and injections fail to provide lasting relief, hip replacement surgery can significantly improve mobility and quality of life.

Compared to conventional hip replacement procedures, DAA offers several advantages. The surgery involves a smaller incision, less blood loss, minimal muscle damage, and lower post-surgical discomfort. Patients are able to regain movement faster and often experience greater confidence during rehabilitation.

One of the most common concerns among patients is the fear of severe pain after surgery. However, with modern pain management techniques and advanced surgical methods, discomfort after DAA hip replacement is usually minimal and manageable. Patients today recover much more comfortably than they did in the past.

Another important factor is the durability of modern implants. Advances in implant technology have significantly improved their lifespan, with many implants lasting more than 25 years. Maintaining a healthy body weight, staying physically active, and following medical advice can further improve the longevity and effectiveness of the implant.

After successful recovery, patients are generally able to resume a normal and active lifestyle. They can return to work, perform household activities independently, and participate in light exercises such as yoga, swimming, and stationary cycling. The primary goal of hip replacement surgery is not just pain relief, but restoring confidence, mobility, and independence.

Preparation before surgery also plays an important role in achieving better outcomes. Patients are advised to maintain controlled blood sugar levels, blood pressure, and overall heart health. Informing doctors about ongoing medications, performing basic physiotherapy exercises before surgery, and preparing a comfortable recovery environment at home can contribute to a smoother rehabilitation process.

Hip pain should never be ignored, especially when it begins affecting daily life and mobility. Timely treatment and the right surgical approach can make a remarkable difference. The Direct Anterior Approach has made hip replacement surgery simpler, safer, and more patient-friendly, helping individuals return to an active and pain-free life much faster than before.

Climate change is increasingly emerging as a major public health threat, contributing to a growing burden of disease worldwide and creating favorable conditions for the spread of infectious illnesses, according to health experts on World Environment Day 2026.

World Environment Day is observed every year on June 5 to raise awareness about the need for immediate action as heatwaves intensify, air pollution worsens, ecosystems degrade, and climate anxiety grows worldwide, even as the world crosses the UN-mandated 1.5°C limit.

The theme for World Environment Day 2026 is "Inspired by Nature. For Climate. For Our Future". It focuses on climate change and the signals nature is sending such as rising seas, raging wildfires, heatwaves and melting glaciers.

To understand the intersection between climate change and health impacts, HealthandMe spoke to two experts.

Heatwaves, Pollution And Food Insecurity

According to Dr. Sabine Kapasi, UN advisor, the consequences are no longer limited to environmental damage. Rising temperatures, worsening air pollution and shifting weather patterns are already affecting human health across the globe.

“Longer and more intense heatwaves are resulting in more cases of heat-related illness. Air pollution continues to exacerbate respiratory diseases, while changing weather patterns are impacting food security and nutrition in many parts of the world,” she said.

Importantly, in India, children, pregnant women and communities living in flood- and drought-prone regions face some of the greatest risks. Women are often disproportionately affected due to challenges related to water supply and sanitation. While India has reduced malaria cases by nearly 80 per cent since 2015, climate change is creating new health challenges that health systems will need to address in the coming years.

Infectious Disease Outbreaks

The expert warned that changing climatic conditions are also increasing the risk of infectious disease outbreaks. Dr. Kapasi told HealthandMe that rising temperatures and altered rainfall patterns are allowing mosquitoes to breed more easily and remain active for longer periods.

Floods further compound the problem by contaminating drinking water, damaging sanitation systems and disrupting healthcare services. Displacement caused by disasters can force families into crowded living conditions, increasing the risk of infections such as cholera, leptospirosis and tuberculosis.

“Recent climate-related disasters in South Asia and Africa have shown how quickly an environmental crisis can turn into a public health challenge,” she noted.

The spread of mosquito-borne diseases such as dengue, malaria and chikungunya is also becoming a growing concern. Health authorities around the world are reporting these diseases in areas where they were previously uncommon.

Globally, countries including Italy, France and Spain have also witnessed an increase in locally transmitted dengue and chikungunya cases over the past decade. In the United States, locally acquired malaria cases were recently reported in Florida and Texas, marking the first such transmission in nearly 20 years.

India is also experiencing rising dengue activity. Dengue outbreaks have become a regular occurrence during the monsoon and post-monsoon seasons in many states. Estimates suggest dengue cases could reach around 278,000 in 2025, up from roughly 230,000 the previous year. Experts say warmer temperatures and changing rainfall patterns are helping disease-carrying mosquitoes survive and spread more effectively.

Climate Change And Shifting Disease Patterns

Dr. Devarsetty Praveen, Program Director at NIHR GHRC for Non-communicable Diseases and Environmental Change, hosted by The George Institute India, in partnership with Imperial College London, said climate change is affecting both communicable and non-communicable diseases.

“Climate change is increasing health risks through rising temperatures, extreme weather events, worsening air quality and changing disease patterns. In India, it is affecting both communicable and non-communicable diseases, with vulnerable populations bearing the greatest burden,” he told HealthandMe.

He noted that research has found that people living with chronic conditions such as hypertension and diabetes are particularly vulnerable to extreme heat, underscoring the growing link between climate change and non-communicable diseases.

Dr. Praveen added that climate change influences disease transmission by altering temperature, humidity and rainfall patterns while also affecting water quality, food systems and interactions between humans, animals and disease vectors.

“These changes can make outbreaks more frequent, more widespread and harder to predict,” he said.

How To Reduce Climate-related Health Risks

To reduce climate-related health risks, the experts recommend staying informed about weather conditions, remaining hydrated, limiting outdoor exposure during extreme heat and taking precautions against mosquito bites.

People with chronic conditions such as hypertension, diabetes, heart disease and kidney disease are advised to maintain adequate medication supplies and consult healthcare providers during periods of extreme heat.

According to the experts, awareness and early action remain critical to protecting public health as climate change continues to reshape disease patterns around the world.

To reduce the risk of mosquito-borne diseases, people should make sure that water does not get collected in buckets, coolers, flower pots or other containers around the home. Additional precautions include the use of mosquito repellents, sleeping under nets when necessary and wearing clothing that covers the arms and legs.

Dr Sabine said food and water safety is particularly important after heavy rain or flooding. Proper food storage, clean drinking water and good hygiene practices can go a long way in preventing many infections. Those with pre-existing medical conditions should also have essential medicines within easy reach during extreme weather.

The United States has been working on reducing smog for more than a decade and has become quite successful in this endeavor, but since 2015, the situation has changed for the worse as a new study reveals that the smog level is once again on the rise, and the main reason behind this is another long-term problem of the nation, wildfire.

The federal regulations tightened on power plants, cars, and diesel engines, which in turn caused a drop in the national smog level by 11% from 2003 to 2015. Since then, cases of wildfire have increased, resulting in the smog level going up by 4%. The study finds that if the current trend continues, it will cause smog to go back up to 2003 levels in 20 years.

The study in the journal Science has also calculated a surge in deaths from ozone attacking lungs by comparing death rates in clean and dirty air. They estimated a surge of 318 American deaths per year since 2013 due to smog.

The co-author of the study, Meng Zhou, a University of Iowa wildfire researcher, said, “For the last 20 years, by regulations, we keep decreasing the emissions." He added, “However, because of wildfires, which are actually from natural hazards, all those kinds of effort were wiped out.”

The study also flagged concerns about the current smog situation and its possible impact on the population. University of Washington public health and climate scientist Kristie Ebi said, “Higher daily ozone concentrations can increase asthma attacks, hospital admissions, and mortality.” She added, “still a very important pollutant, which is why it's regulated.”

The research finds that the heavy wildfire smoke seasons of 2022, 2023, and 2024, mainly in Canada, created a massive amount of smog, and this then came down south. As a result, about 43 million people got exposed to smog levels that exceeded the current EPA safety standards. The wildfires in Canada have been particularly severe since 2022.

The problem is also with the massive wildfires in the mainland US, as the National Interagency Fire Center's data also shows that the average amount of land in the US that wildfires burn every year has increased by 9% higher than it was from 2003 to 2014.

What Are The Possible Health Impacts?

There are many short-term and long-term impacts on public health from the constant exposure to air pollution. As per IQAir, in the short term, people experience irritation in the eyes, throat, and nose, along with irregular heartbeats, asthma attacks, coughing, chest tightness, and difficulty breathing.

Prolonged exposure also intensifies these risks and leads to long-term effects such as chronic respiratory illnesses like bronchitis, asthma, and emphysema. Pollutants can also damage lung tissue, increasing the likelihood of lung cancer. Air pollution also leads to an increased risk of heart attacks and strokes, and could also be linked to premature death.
