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'.
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.
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.
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.
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.
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.
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.
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.

Women who are conflicted while choosing between an injectable contraceptive, a copper intrauterine device (IUD) or a hormonal implant may not need to worry about its impact on human papillomavirus (HPV).
HPV is one of the most common sexually transmitted infections worldwide. While many HPV infections go away on their own without causing problems, some high-risk types can persist and increase the risk of cervical cancer in the long run.
Before this study, scientists debated whether hormonal contraceptives could affect a woman's immune response, making it easier to contract HPV or harder for the body to clear the infection.
According to a new study published in The Lancet Regional Health – Africa, your choice of contraception may not have an impact on the risk of contracting HPV.
Researchers found that women using a commonly used injectable contraceptive known as depot medroxyprogesterone acetate (DMPA-IM), copper IUDs, and levonorgestrel implants had similar chances of contracting HPV and clearing existing infections.

The researchers examined data from women who participated in the large ECHO (Evidence for Contraceptive Options and HIV Outcomes) clinical trial. Participants were randomly assigned to one of three contraceptive methods:
They then compared how often women acquired HPV during the study and how often those who already had HPV were able to clear the infection naturally. The analysis found no meaningful differences between the three contraceptive methods.
Women using the injectable contraceptive were no more likely to acquire HPV than those using a copper IUD or a hormonal implant. Similarly, women across all three groups cleared HPV infections at comparable rates.

Earlier studies finding the link between hormonal contraceptives and HPV have reported mixed results. Some suggested that hormonal birth control might increase the risk of HPV infection or make infections last longer, while others found no clear outcomes.
This new research provides stronger evidence because it is based on a randomized clinical trial. The findings suggest that the type of contraceptive a woman chooses is unlikely to have an impact on her risk of getting HPV or her body's ability to clear the infection.
The study allows women to choose between these commonly used contraceptive methods based on factors such as effectiveness, convenience, side effects, and personal preference, rather than concerns about HPV risk.
However, experts stress that no contraceptive method protects against sexually transmitted infections, including HPV. Using condoms can help reduce the risk of HPV and other STIs.
The human papillomavirus causes more than 200 known infections. While some types lead to benign skin warts, others are responsible for severe health threats, such as cervical, throat, anal, and penile cancers. The HPV vaccine provides strong protection against the most lethal strains, avoiding long-term health complications.
The HPV vaccine helps the immune system recognize and fight off high-risk strains of the virus before they cause harm. It protects against:
Experts also stress that HPV vaccination and regular cervical cancer screening remain the most effective ways to prevent cervical cancer and detect abnormal changes early.

People in the UK can, from today, access the Wegovy weight loss pill through pharmacies with a doctor's prescription. It is the first oral glucagon-like peptide-1 (GLP-1) medicine approved in the UK for weight loss.
The Medicines and Healthcare products Regulatory Agency (MHRA) approved the tablet on June 11, marking the first oral GLP-1 treatment available in the country for obesity management.
"Having met the MHRA's rigorous standards of safety, quality and effectiveness, the semaglutide tablet has been approved in the UK for weight loss and weight management," Julian Beach, Executive Director of Healthcare Quality and Access at the MHRA, said in a statement.
"As with all GLP-1 receptor agonists, this is a prescription-only medication," Beach added.
Novo Nordisk called it an "important milestone for obesity care in the UK".
"For the first time, people living with obesity have access to a GLP-1 treatment in a daily pill, allowing them the choice and flexibility of oral treatment to support their long-term weight management," said Sebnem Avsar Tuna, General Manager at Novo Nordisk UK.

Patients are advised to carefully follow the instructions in the Patient Information Leaflet.
Semaglutide is a GLP-1 receptor agonist that mimics the action of the naturally occurring GLP-1 hormone released after eating.
It acts on areas of the brain that regulate appetite by:
Not yet. Although the medicine has received MHRA approval, it is not currently available through the NHS.
The MHRA said NHS availability will depend on the usual evaluation process by the National Institute for Health and Care Excellence (NICE).
NICE said Novo Nordisk has not yet formally approached it, but that it is in active discussions with the company, BBC reported.
The most commonly reported side effects are gastrointestinal and include:
The MHRA said it will continue to monitor the medicine's safety and effectiveness. Anyone experiencing side effects should speak to their doctor, pharmacist, or nurse and report them through the MHRA Yellow Card scheme.
Community pharmacies say they are preparing for a surge in demand following the launch. The National Pharmacy Association (NPA) urged patients to obtain the medicine only from regulated pharmacies following a proper clinical consultation.

The Democratic Republic of the Congo (DRC) is battling one of its deadliest Ebola outbreaks in recent years. While it is driving innovation in medical science with new clinical trials and diagnostic tests, it is also a stark reminder of the urgency to contain the outbreak as soon as possible.
According to the latest data, the death toll in DRC has now crossed 500 with at least 1,528 cases that are reported and confirmed.
While Ebola is not a new disease, the current outbreak stands apart because it is being caused by a rare strain of the virus, Bundibugyo.
Unlike previous outbreaks dominated by the Zaire strain of Ebola, the current epidemic, caused by the Bundibugyo virus, is a much less common species of the Ebola virus family.
The rarity of the strain has created unique scientific and emergency public health challenges, as there is currently no licensed vaccine designed to protect against Bundibugyo Ebola virus.
During outbreaks caused by the Zaire strain, vaccination became an important part of outbreak control. In the current epidemic, however, public health officials are being forced to rely heavily on rapid diagnosis, infection prevention, surveillance, and existing medical care.

In a major scientific breakthrough, the World Health Organization (WHO) recently added the first molecular diagnostic test for the Bundibugyo Ebola virus to its Emergency Use Listing (EUL).
The test detects the virus's genetic material in blood samples, enabling laboratories to confirm infections more quickly and accurately.
WHO and its partners have launched the first clinical trial specifically evaluating treatments for Bundibugyo Ebola virus disease.
Researchers are testing the experimental monoclonal antibody MBP134, the antiviral drug remdesivir, and a combination of both to determine whether they can improve survival.
The Bundibugyo virus was first identified in Uganda in 2007 and has caused only a few outbreaks since then. As infections have been relatively uncommon compared to the Zaire strain, researchers have had limited opportunities to develop vaccines, treatments and diagnostic tests.
Due to this, healthcare workers have been compelled to rely primarily on rapid isolation of patients, intensive supportive care, contact tracing, and strict infection prevention measures to slow transmission.
Currently, Eastern DRC is the hotspot for the Bundibugyo Ebola outbreak, where conflict, population displacement, skepticism, and insecurity have made it difficult for health workers to reach affected locations.
Here, access to healthcare still remains uneven in many areas. Additionally, movement of people across districts and states in the country can accelerate the spread of infection significantly.
As scientists race to validate new diagnostics and evaluate experimental treatments, the Bundibugyo outbreak is becoming more than a public health emergency. It is also serving as a critical test of how quickly the global health community can develop and deploy new tools against an emerging infectious disease.
