When the sun is out after a long winter, every one loves it. But not the people of Canary Islands. Tourists there are being warned about the "unusually high risk" of UV rays this week. The Ministry of Health for this holiday destination has urged both, residents and visitors to take extra precautions and preventative measures to limit the impact of sun exposure over their body and skin.

The Ministry observed Aemet, Spain's national weather agency for the forecast which showed higher than normal UV or ultraviolet radiation levels in the region. It is in this backdrop that everyone in the region are requested to be extra careful when they are out in the sun. UV levels are set to reach 7, which is a 'high risk' in La Palma, El Hierro, La Gomera and Gran Canaria. Other regions like Tenerife, Fuerteventura and Lanzarote are expected to reach a level 6, which is also classed as 'high risk'.

UV Index Explained

As per the World Health Organization (WHO), a UV index is a measure of the level of UV radiation, which ranges from zero upward. The higher the UVI, the greater potential for damage to skin and eye and the less time it takes for harm to occur, notes WHO.

The range 1 to 2 represents a low risk, 2 to 5 is moderate, 6 to 7 is at high risk, 8 to 10 is at very high and anything over 11 is extremely risky for anyone to stay out.

UV radiation levels fluctuate throughout the day, with the highest values occurring during the four-hour period around solar noon. The reported UV Index (UVI) typically reflects this daily peak. Depending on geographic location and the use of daylight saving time, solar noon falls between 12 p.m. and 2 p.m. In some countries, sun protection advisories are issued when UV levels are expected to reach 3 or higher, as exposure at these levels increases the risk of skin damage, making protective measures essential.

What happens to you when you are out in sun for too long?

While sun bathing is good, being out in the sun when the UVI indicates a high or very high risk, may cause you health concerns. It can lead to sunburn, premature skin aging, incresed risk of skin cancer, eye damage and in severe cases, heat related disease.

Sunburn

It is one of the most common skin injury which happens when there is excess exposure to UV radiation from the sun. This happens when the UV radiation directly damages the DNA skin cells. These damaged cells die and shed, this is why people experience peeling after getting a sunburn.

Dehydration

This is also a common occurrence when your body loses too many fluids or electrolytes. It can also interfere with your normal body functions. You may feel dehydrated, especially when you are out in the sun, but not well hydrated. The most common symptoms are dizziness, fatigue and headache on hot days.

Hyponatremia

This is an electrolyte disorder in which your body experiences low sodium in blood. The symptoms could lead to nausea, confusion and even weakness. There are extreme cases when one may have seizures, slip into coma or die.

Heat Exhaustion

This is one of the most common consequence of being out under the hot sun. Dehydration with prolonged heat exposure can lead to heat exhaustion.

Heatstroke

When you are out under the sun and your body's core temperature cross 104°, heatstroke may occur. This is also known as sunstroke. As per the Centers for Disease Control and Prevention (CDC), it causes more than 600 deaths each year in the United States.

In a significant move for public health, Telangana has declared cancer as a notifiable disease and launched a cancer registry.

The state reports about 55,000 to 60,000 new cancer cases every year.

A cancer registry would help the government in having accurate data for preparing better plans to deal with the spread of cancer, said the state Health Minister C Damodar Rajanarasimha.

He noted that the state government has expanded healthcare to treat cancer by establishing Day Care Cancer Centers in district headquarters towns. Further, the government is conducting health checks for 46 lakh members of women self-help groups (SHGs).

In addition, the government would also start Regional Cancer Centers and take measures to detect diseases like cancer through AI.

Is Cancer A Notifiable Disease In India?

A notifiable disease means that it is required by law to be reported to government authorities. The mandatory reporting facilitates surveillance, helps control.

Cancer is not currently a centrally mandated notifiable disease across all of India, as the central government focuses on surveillance through the National Cancer Registry Programme (NCRP). The NCRP was established in 1981 under the Indian Council of Medical Research (ICMR).

However, over 17 states and UTs in India have declared cancer a notifiable disease to improve data, registry accuracy, and early detection.

India operates two primary types of cancer registries to monitor the disease burden:

• Population-Based Cancer Registries (PBCRs): These collect data on all new cancer cases and mortality within a specific geographic area. Nearly 40 PBCRs are covering approximately 16.4 percent of India's population.

• Hospital-Based Cancer Registries (HBCRs) record information on patients diagnosed or treated at specific hospitals. There are currently over 269 HBCRs across the country.

“Cancer is emerging as a major public health problem in India. There is a need to collect accurate and robust data on cancer for planning optimal cancer care services across the country,” Dr (Prof) SVS Deo, Chairman – Surgical Oncology, Max Super Speciality Hospital, Saket, told HealthandMe.

The Role Of A Cancer Registry

Dr. Raghav Kesri, Senior Consultant & HOD, Medical Oncology, Yatharth Hospital, Greater Noida, said that cancer registration is significant in determining the types of cancers that are most common in a certain region.

It also allows us to pinpoint the risk factors that might contribute to the increasing number of cancer cases. In India, there are cancer registrations conducted by individual states and the country as a whole.

“These statistics allow us to analyze the trend when coupled with demographics, giving us important information to consider. This is critical knowledge to ensure that we go in the right direction in our health policies, including cancer prevention, early detection, and treatment,” Kesri told HealthandMe.

How To Prevent Cancers

Approximately 60 percent of cancers in India are preventable, including tobacco-related (lung and head and neck cancers), infection-related (stomach, liver, and cervical cancer), and lifestyle-related cancers (breast and colorectal cancers).

Common ways to prevent cancer include:

• Eating a healthy diet rich in fruits and vegetables
• Avoiding alcohol
• Quit smoking
• Avoiding tobacco consumption
• Stay physically active
• Maintain healthy weight.

Another alarming study has highlighted the growing risk of drug resistance, this time in pathogens responsible for eye infections.

A team of Indian researchers has detected multidrug-resistant bacteria in more than 45 per cent of isolates from patients with eye infections.

The study, jointly led by CSIR-Centre for Cellular and Molecular Biology (CCMB) and LV Prasad Eye Institute (LVPEI), also reported widespread resistance to fluoroquinolones — one of the main classes of antibiotics — across all pathogens examined.

Further, the team found samples with vancomycin-resistant Staphylococcus aureus and extensively drug-resistant (XDR) Klebsiella pneumoniae strains involved in eye infections.

"These findings are worrying because they can spread their AMR genes to other bacteria, too. Also, these pathogens can infect other parts of our bodies," said Karthik Bharadwaj from CCMB.

The study, published in 'Communications Biology', raise concerns over current treatment approaches in ophthalmic care.

How Was The Study Conducted?

Researchers described the work as one of the most comprehensive genomic analyses of eye pathogens from India to date. CCMB handled genomic and bioinformatics analysis, LVPEI contributed clinical expertise, patient samples, and microbiological characterization, PTI reported.

Whole-genome sequencing helped identify new resistance mechanisms and mutations, offering deeper insight into how these pathogens evolve and spread.

Researchers said the high prevalence of resistance makes such an approach increasingly unreliable.

The study underscores the need for microbiology-guided diagnosis and treatment, particularly in severe infections such as microbial keratitis and endophthalmitis.

"While genomic tools are not yet part of routine clinical workflows, the insights generated through this study provide a critical foundation for developing region-specific treatment guidelines and strengthening antimicrobial stewardship efforts in ophthalmology," said Dr Joveeta Joseph, head of microbiology at LVPEI.

Researchers also stressed that eye infections should not be viewed in isolation. The microbes involved often originate from the skin or environment, linking ophthalmic infections to the broader AMR burden.

"This study positions the eye as a valuable site for AMR surveillance in the environment around us," said Dr Prashant Garg, executive chair, LVPEI.

Increasing Drug Resistance In India

A recent Lancet Study reported that drug resistance is driving severe typhoid disease, hospitalization, and death among children under-5s in India.

Another 2024 Indian Council of Medical Research (ICMR)-led study also revealed a significant increase in antibiotic resistance and a decrease in the effectiveness of key antibiotics. This indicates a growing public health threat that requires immediate attention.

It showed E. coli, a common bacterium found in both ICU and outpatient settings, demonstrated a concerning rise in resistance to antibiotics like cefotaxime, ceftazidime, ciprofloxacin, and levofloxacin.

Rising Global Antimicrobial Resistance

Antimicrobial resistance (AMR) occurs when germs develop the ability to defeat the drugs designed to kill them.

It is one of the 10 top global health threats, undermining the effectiveness of essential treatments and placing millions at risk of untreatable infections.

As per WHO data, AMR is an urgent global public health threat, killing at least 1.27 million people worldwide and associated with nearly 5 million deaths in 2019.

The WHO, in a 2025 report, noted that one in six laboratory-confirmed bacterial infections causing common infections in people worldwide in 2023 were resistant to antibiotic treatments.

Panic has gripped the residents of two villages in Rajasthan's Salumbar district, where five children have reportedly died within five days. The reason: an unknown disease characterized by a sudden onset of fever that worsens rapidly, and claims the lives of children within 24 hours.

According to officials, the children who died were between 2 and 4 years old, and all of them developed high fever, convulsions, and vomiting before their condition worsened rapidly.

Besides the five children who died, another 8 children are reportedly showing similar symptoms of the unknown disease.

The incident has been reported from Ghata and Lalpura villages in Lasadiya block.

The Disease Yet To Be Identified

The deaths have created fear among villagers, who submitted a memorandum to the SDM and health officials, seeking immediate action and identification of the disease.

District officials, along with a medical team, have reached the villages. The District Collector has ordered an inquiry. Medical teams are currently stationed in the villages, according to local media reports. Blood samples and other tests are being conducted to check for viral infection, brain fever, or any seasonal illness.

After preliminary treatment, five of the eight children newly affected with the mystery illness were referred from Lasadiya CHC to Udaipur District Hospital. Meanwhile, three children were referred to Salumbar District Hospital.

"Seventeen teams have been deployed in Lalpura and Ghata villages. Around 562 families live in this area," said Dr. Dinesh Rai Sapela, Additional District Collector.

Health teams are also conducting door-to-door screening, as well as collecting blood samples. These samples have been sent to RNT Medical College in Udaipur for testing.

“The exact cause behind the deaths is not yet known. It could be a viral infection or a seasonal disease, but confirmation will only come after test results,” said BCMO Dr Sintu Kumawat.

Meanwhile, Gayatri Rathore, Principal Secretary of the Medical and Health Department, stated that the Chief Medical and Health Officer of the Salumbar district has been instructed to form teams of health workers to ensure intensive screening of children exhibiting fever symptoms—not only in the affected villages but also throughout Salumbar and its surrounding regions, media reports said.

“Immediate treatment will be provided to any child showing symptoms. Critically ill children are to be referred without delay to district hospitals or medical college facilities,” Rathore said.

Authorities have also initiated preventive measures against possible mosquito-borne diseases, including anti-larval activities, source reduction, and fogging operations in the affected areas.
