World Asthma Day 2025: Theme, treatment, and tips for better care
Barkha Mathur New Delhi
For the millions living with asthma, the simple act of breathing can be a daily challenge. World Asthma Day 2025, on Tuesday, is a global reminder of the importance of respiratory health and the urgent need to make asthma care accessible to everyone. Whether you live with asthma, care for someone who does, or simply want to learn more, this day puts the spotlight on equitable treatment and empowering communities to take control of their health.
What is World Asthma Day and why is it observed globally?
World Asthma Day is observed annually on the first Tuesday of May to raise awareness about asthma, a chronic respiratory condition that affects millions of people globally. This year, it falls on May 6. Organised by the Global Initiative for Asthma (GINA), the day highlights the urgent need for accessible, equitable, and effective asthma treatment worldwide.
Key asthma symptoms: What to watch for and when to seek help
According to the World Health Organization (WHO), asthma is a chronic inflammatory disease of the airways that leads to recurring episodes of breathlessness, wheezing, chest tightness, and coughing. It can vary in severity and frequency, and often worsens during the night or early morning.
WHO says the symptoms of asthma can vary from person to person and can sometimes get significantly worse. This is known as an asthma attack. Symptoms are often worse at night or during exercise.
Common symptoms of asthma include:
A persistent cough, especially at night
Wheezing when exhaling and sometimes when inhaling
Shortness of breath or difficulty breathing, sometimes even when resting
Chest tightness, making it difficult to breathe deeply
According to the WHO, over 260 million people are affected by asthma worldwide, and it remains one of the leading causes of non-communicable disease-related deaths, especially in children.
Acute vs chronic asthma: Understanding the difference for better care
Understanding the types of asthma is crucial for effective treatment. Acute asthma involves sudden and severe airway obstruction, often triggered by infections, allergens, cold air, or stress. It requires immediate intervention to prevent complications. Chronic asthma, on the other hand, is marked by long-standing inflammation and ongoing sensitivity to environmental triggers like dust, smoke, and air pollution.
As Dr Anshula Tayal Bansal, Consultant – Paediatric Pulmonology & Intensive Care at Manipal Hospital Goa, explains, 'An understanding of acute and chronic asthma is important for timely and successful intervention in the treatment of a chronic inflammatory disease of the airways, known as asthma, with episodes of acute, reversible airway obstruction.'
She underscores the need for accurate diagnosis and personalised care strategies for each type of asthma, especially as unmanaged chronic asthma can lead to irreversible changes in lung function.
What causes asthma? Top risk factors you should know
Asthma is a complex condition with no single, definitive cause. However, according to WHO, several risk factors have been identified that increase a person's likelihood of developing it:
Family history and genetics: Having a close relative with asthma—such as a parent or sibling—significantly raises the risk
Allergic conditions: Individuals with conditions like eczema or allergic rhinitis are more likely to develop asthma
Urban lifestyle and pollution: Air pollution and limited green spaces contribute to higher asthma rates in urban areas
Early life influences: Factors like premature birth, low birth weight, and early respiratory infections increase risk
Environmental irritants: Exposure to dust, mould, fumes, and chemicals can worsen symptoms
Obesity: Excess weight influences lung function and inflammation, raising asthma risk
How to manage asthma: Doctor-recommended tips for symptom control
Managing asthma effectively, especially during the warmer months and high-pollution periods, requires both preventive and reactive strategies. Here are expert-recommended tips to help manage symptoms and reduce the risk of attacks:
Schedule outdoor activities early in the day when pollution and pollen levels are lower
Consult your pulmonologist regularly to adjust medications based on seasonal or lifestyle changes
Store inhalers in a cool, shaded place to maintain their efficacy
Take controller medications as prescribed, and always keep a rescue inhaler handy
Stay hydrated to help thin mucus and ease breathing
Monitor local weather and air quality reports, especially during high-smog days
Use High-Efficiency Particulate Air (HEPA) filters or air purifiers at home to minimise exposure to allergens and pollutants
Why World Asthma Day matters: Global awareness and impact since 1998
World Asthma Day was first held in 1998, with participation from over 35 countries in the first World Asthma Meeting in Barcelona, Spain. It was initiated by GINA to enhance asthma awareness and education globally. Over the years, the day has become a crucial annual event aimed at:
Educating the public and patients about asthma
Promoting preventive measures and effective treatment
Reducing stigma and misinformation
Encouraging governments and stakeholders to prioritise asthma care in health policies
World Asthma Day 2025 theme: Make inhaled treatments accessible for all
This year's theme, 'Make Inhaled Treatments Accessible for ALL', emphasises the need to ensure that essential asthma medications such as inhaled corticosteroids and reliever inhalers are affordable and widely available, especially in low- and middle-income countries (LMICs).
Inhaled treatments are crucial for both daily symptom control and emergency relief. Yet, millions around the world lack access due to economic, geographic, and systemic healthcare barriers. The 2025 theme calls on governments, pharmaceutical companies, and international health bodies to improve supply chains, reduce costs, and promote equitable distribution of these life-saving treatments.
World Asthma Day initiatives: Awareness, screenings, and community action
World Asthma Day sees a wide range of community outreach efforts, including:
Free health screenings and lung function tests
Public awareness campaigns in schools, workplaces, and public spaces
Workshops and webinars by healthcare professionals
Social media drives to spread accurate information and support networks
These initiatives aim to empower individuals with knowledge about early symptoms, the importance of regular check-ups, and the availability of effective treatments.

All you need to know about: rabies
The Supreme Court's recent ruling directing the Delhi government and local bodies to immediately capture stray dogs, detain them in pounds created across the national capital territory and never let them loose back into public spaces, has ignited a controversy. One of the points the court made was about children lost to rabies due to stray dog bites. What is rabies and what is the extent of the public health burden caused by it? Here is all you need to know about rabies. What is rabies? Rabies is a deadly, fatal, zoonotic viral disease. The rabies virus (RABV) is generally transmitted through the bite or scratch of an infected animal. Rabies infects mammals, including dogs, cats, livestock and wildlife. Other animals that carry rabies include: bats, raccoons, skunks and foxes. According to the World Health Organization (WHO) however, dog bites and scratches cause 99% of the human rabies cases. In rare cases, rabies is transmitted through the infected saliva of an animal coming into contact with an open wound or mucous membranes such as in the eyes or mouth. What makes this virus dangerous is that once clinical symptoms begin, there is no cure: it is fatal. However, rabies can be prevented through prompt vaccination after exposure. The WHO classifies rabies as a neglected tropical disease (NTD) and states that children between the ages of 5 and 14 are frequent victims. What are the signs and symptoms of rabies? The rabies virus has an incubation period. This means it can spend several days or weeks (up to two or three months) in the body before symptoms appear. The incubation can period can vary based on factors such as the location of the wound. It is during the next phase, when the virus travels to the central nervous system, known as the prodromal phase that symptoms appear. Initial symptoms may be similar to those of the flu and may include: fever, headaches, discomfort, vomiting, weakness and prickling or tingling at the site of the bite. The disease then progresses into a severe form, usually about two weeks after the first symptoms. At this stage, the acute neurologic phase, the rabies virus begins damaging the brain and spinal cord. In a majority of people symptoms of 'furious rabies' appear, and these include aggressive behaviour, hallucinations, hyperactivity, fear of water (hydrophobia), excessive salivation, fear of air or drafts and delirium. A smaller number of patients have symptoms of 'paralytic rabies' which involves paralysis of the muscles and weakness, starting from the site of the bite and progressing to the rest of the body, eventually leading to a coma. Furious rabies usually lasts a few days while paralytic rabies can last longer. The WHO states that the paralytic form of rabies is often misdiagnosed, contributing to the under-reporting of the disease. What is the vaccination available? There are currently no WHO-approved tools to diagnose rabies prior to the onset of clinical symptoms, making it crucial to see a healthcare provider immediately after a bite, scratch or contact with a wild animal, or a potentially infected pet animal. Healthcare providers must make an accurate risk assessment to decide on vaccination. The wound must be cleaned gently and thoroughly as well. Vaccines for rabies are: pre-exposure prophylaxis (PrEP) which is recommended for people in high-risk professions where they may come into contact with infected animals or those travelling to such areas and post-exposure prophylaxis (PEP), which is given after exposure, and which prevents the virus from entering the central nervous system. It is important to note that taking the PrEP does not mean that PEP is not needed: even those who have taken the PrEP must seek care after exposure. As listed under the WHO - Prequalification of Medical Products, as of 2024, there are only three WHO pre-qualified human rabies vaccines available globally: RABIVAX-S by Serum Institute of India Pvt. Ltd., VaxiRab N by Zydus Lifesciences Limited, and VERORAB by Sanofi Pasteur. What do you do if bitten or scratched by an animal? If you've been bitten by animal that may have rabies, or even scratched or licked it is important to seek medical attention. Wash the wound thoroughly with soap and water and then go to your healthcare provider, giving as much detail as possible about the animal and the kind of contact. The post exposure prophylaxis (PEP) rabies vaccine usually consists of four shots over 14 days. Your doctor may also give you shots of human rabies immunoglobulin, given into or around the wound in order to give the body antibodies to destroy the virus around the wound. (This is not taken if a vaccination has already been taken prior to exposure). If treatment is availed of promptly after exposure, it is usually effective at preventing rabies. What is the situation in India? In India, there were more than 37 lakh cases of dog bites and 54 suspected human rabies deaths reported during 2024, according to a written reply given by S.P. Singh Baghel, Minister of State for Fisheries, Animal Husbandry and Dairying to the Lok Sabha. A January 2025 research paper, 'Estimates of the burden of human rabies deaths and animal bites in India, 2022–23: a community-based cross-sectional survey and probability decision-tree modelling study' however found that the estimated human rabies death occurring annually in India was 5,726. It also found gaps in vaccine access and completion of vaccine courses. The WHO notes that India is endemic for rabies, and accounts for 36% of the world's rabies deaths.

Covid variant XFG surges 14% in US as WHO tracks spread to 38 nations, India confirms 163 cases; here's what we know so far
The United States is reporting a steady increase in Covid-19 cases linked to the XFG variant, now the country's third-most common strain this summer. Also known as 'Stratus,' XFG is a recombinant of two earlier Omicron subvariants—LF.7 and LP.8.1.2—first identified in Southeast Asia in January 2025. The World Health Organization (WHO) has placed XFG under its 'variant under monitoring' category. This means that while it is not considered a major health threat at present, its spread is being closely tracked. Global and national spread Data from the US Centers for Disease Control and Prevention (CDC) shows that XFG represented 0 per cent of US cases in March, rising to 2 per cent in April, 6 per cent in May, and 14 per cent by late June. This puts it behind only two other variants in prevalence. The variant has also been reported in several European nations. WHO figures indicate its global share rose from about 7 per cent in early May to 22.7 per cent by late June, spanning at least 38 countries. ⚠️ BREAKING: COVID-19 Cases Rising in 25 US States, Including California, Florida, and Texas, Signaling Onset of 'Summer Wave' In India, the Indian SARS-CoV-2 Genomics Consortium (Insacog) recorded 163 confirmed cases of XFG by the end of June. Symptoms and health impact So far, XFG does not appear to cause symptoms different from or more severe than those seen with other Omicron strains. Variants like XFG can develop when a person is infected with two versions of the virus simultaneously, allowing genetic material to mix. Reported symptoms include: Fever or chills Cough Shortness of breath or breathing difficulty Sore throat Nasal congestion or runny nose New loss of taste or smell Fatigue Muscle or body aches Headache Nausea or vomiting The CDC advises immediate medical help for chest pain, confusion, difficulty staying awake, or pale/blue lips, skin, or nail beds. Expert assessment and vaccination guidance WHO and expert evaluations confirm that: Public health risk remains low No evidence of increased severity Current vaccines continue to protect against symptomatic and severe illness Precautionary measures Health authorities recommend the following steps: Get tested if symptoms appear Stay home if unwell Maintain good hygiene practices Keep vaccinations and boosters up to date While XFG is spreading quickly, current evidence suggests that with routine precautions and existing vaccination coverage, the impact can be managed effectively.

New Covid ‘Stratus' variant now the third most common in US: Symptoms, spread and response
Covid cases growing in most states Live Events 'Stratus' variant becomes more prominent WHO risk assessment and vaccine effectiveness Covid 'Stratus' variant: Symptoms and public advice Concerns over vaccine policy changes (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel The United States is seeing a rise in Covid-19 activity, with the sharpest increases recorded in the west. The Centres for Disease Control and Prevention (CDC) says that nationwide wastewater virus levels have climbed from 'low' to 'moderate' in the past highest readings are concentrated in Alaska, California, Colorado, Nevada and Utah, all classified as 'high'. Louisiana leads in the southeast, where levels are also elevated.'Wastewater monitoring can detect viruses spreading from one person to another within a community earlier than clinical testing and before people who are sick go to their doctor or hospital,' the CDC says. 'It can also detect infections without symptoms. If you see increased wastewater viral activity levels, it might indicate that there is a higher risk of infection.'Wastewater surveillance is being used as an early-warning system for new waves, with California's own data now showing higher levels than during last winter's of Tuesday, the CDC estimates cases are rising or likely rising in 45 states, up from 40 last week. Only Alaska, North Dakota, Maine and New Hampshire showed no change. Wyoming's trend was not the pace of increase is slower than in past surges, health officials say immunity from previous infections and vaccinations varies widely, making it hard to predict how severe the current wave could XFG variant, nicknamed 'Stratus,' is now the third most common strain in the US this summer. First detected in Southeast Asia in January, it went largely unnoticed in America until May. By late June it accounted for 14 per cent of cases, behind NB.1.8.1 and is a combination of the F.7 and LP.8.1.2 variants, the latter being the second most prevalent in the country. It carries mutations that may help it evade immune defences, though scientists say it is less likely to be highly contagious than other dominant strains.'There is currently no clear evidence that XFG causes more severe disease or significantly different symptoms than earlier Omicron variants,' said Subhash Verma, professor of microbiology and immunology at the University of Nevada, Reno. 'Importantly, there are no immediate public health concerns associated with this variant.'In June, the World Health Organization placed XFG on its watchlist but rated its global public health risk as low. 'Currently approved COVID-19 vaccines are expected to remain effective to this variant against symptomatic and severe disease,' the WHO said in its June CDC's shift to longer reporting timeframes is partly due to lower data submissions from states, which means the real spread may be higher than official CDC lists the common Covid-19 symptoms as fever or chills, cough, shortness of breath, sore throat, congestion, loss of taste or smell, fatigue, muscle aches, headache, nausea or vomiting. Hoarseness has been reported anecdotally with XFG, though there is no confirmed are advised to seek urgent medical attention for breathing difficulties, persistent chest pain, confusion, inability to wake, or changes in skin colour such as pale, grey or blue lips and nail increase in cases comes shortly after the US Department of Health and Human Services announced it will terminate 22 federal contracts for mRNA-based vaccines. The move has sparked debate about the future of a technology credited with saving millions of lives during the a CBS interview in July, physician Jon LaPook said the pattern of rising summer cases is now familiar. 'We now know that there's a winter spike and then there's a summer spike,' he said. 'And every year, the number of deaths, the number of hospitalisations, is gradually going down each season. So that's the good news.'However, experts say it is still too soon to tell how big the late-summer wave will be, especially with changes to vaccine recommendations and varying levels of immunity across the population.
