Chikungunya Disease and Prevention (Credits-Freepik)
Overview
This is a disease that is transmitted from mosquitoes to humans and affects many people in the world. Found in densely populated countries and continents, like Africa, Asia and the tropics of the Americas, this has severe symptoms. This viral disease is caused by the Chikungunya virus of the Togaviridae. First identified in the United Republic of Tanzania in 1952 and subsequently in other countries like Africa and Asia. Since 2004 the outbreak of CHIKV virus has become more widespread and caused partly due to the viral adaptations allowing the virus to be spread more easily by Aedes albopictus mosquitoes. The transmission has been noted to persist in countries where there is a large population, but interestingly, the transmission has been interrupted on islands where a high proportion of the population is infected and then immune.
Symptoms
The onset of the disease is usually in 4-8 days and after a bite of an infected mosquitoes, it is characterized by an abrupt onset of fever and then joint pain. This joint pain is severed and lasts for a few days but may prolong for months maybe even years. Other signs are joint swelling, muscle pains, headache, nausea, fatigue and rash. These symptoms also overlap with those of dengue and Zika virus and can be misdiagnosed. Most people fully recover from the infection and experience only mild and sometimes the infection even goes unrecognized. However, there have been cases of eye, heart, and neurological complications. The elderly and newborns are more susceptible to the infection and if they have any underlying conditions then they are likely to become severely ill increasing the risk of death.
Diagnosis and treatment
The diagnosis and treatment of the virus may be done by blood sampling and other tests like reverse transcriptase–polymerase chain reaction (RT–PCR). Other tests detect the activity of the antibodies. These can be detected in the first week after illness onset and can be detected for about 2 months. Many clinical measures can be taken to address fever and joint pain. But there is no specific anti-viral drug treatment for the virus.
Preventing Chikungunya
As this disease is caused by the bite of a mosquito, you must reduce the opportunities to let the mosquito breed. Mosquitoes bite during the day and night, and for people who live in risk areas like southeast Asia, Africa and tropical regions of America, many outbreaks happen each year. The best way to prevent it is to protect yourself from the mosquito's bite. You also must get vaccinated before travelling to any of these regions. Use insect repellent, and wear long-sleeved shirts and pants. You can also treat your clothes and gear with permethrin. As we all know, they tend to breed in humid places and places where they have access to water, so try to close the rooms that are air-conditioned with screens and windows. Use nets and mosquito repellents if you are sleeping outside. There are many different types of mosquito repellents like paper, liquid etc, and they are quite effective. If your job needs, you to be stationary for long hours or frequently go outside you must take the necessary precautions.

Weight-loss jabs, or GLP-1 receptor agonists, have provided many people with results that diets alone could not achieve. For those struggling with constant cravings, these medications have quieted the persistent “food noise” that often drives overeating. They have transformed not only body shapes but also self-confidence and daily habits.
Yet questions remain: can people safely stop taking these drugs, and what happens to the body when they do? These are still largely unknown, as the drugs are relatively new. GLP-1s mimic a natural hormone that controls hunger, but the long-term effects are only beginning to be understood. Additionally, for the estimated 1.5 million people in the UK paying privately for these injections, maintaining treatment can be costly.
Two women, Tanya and Ellen, share their personal experiences with the BBC on weight-loss jabs and what life was like when they attempted to stop.
Tanya, a sales manager in the fitness industry, initially started taking Wegovy to challenge her own perceptions about weight and authority. She often felt overlooked or undervalued because of her size, and hoped that losing weight would change how others treated her, as per BBC.
Early in treatment, Tanya experienced side effects including nausea, headaches, sleep issues, and hair loss, which she describes as clumps coming out. Despite this, she steadily lost weight—six stone (38 kg) over 18 months—and the injections quieted the relentless urge to eat.
However, every time she tried to stop, her appetite surged within days, leaving her horrified at her own eating. Now, Tanya continues the medication, feeling it has become essential to maintaining her weight and the confidence it brings.
Wegovy’s manufacturer, Novo Nordisk, stresses that treatment decisions should be made with medical guidance and that side effects must be considered. Lifestyle GP Dr. Hussain Al-Zubaidi likens stopping GLP-1s abruptly to being hit by a “tsunami” of hunger.
Research shows that within one to three years of stopping these medications, people can regain 60–80% of the weight they lost. This highlights how these drugs work not just by reducing appetite temporarily but by fundamentally altering hunger cues.
Ellen turned to Mounjaro after reaching a critical point in her life. Her weight had put her at risk during surgery, and emotional binge eating dominated her daily habits. Once on the medication, Ellen noticed her compulsive eating completely stopped.
Over 16 weeks, she lost 3 st 7 lb (22 kg) and began tapering off the injections over six weeks. She focused on developing a healthier relationship with food, creating balanced meals, and incorporating exercise into her routine. Despite some weight creep after stopping, she has since lost a total of 51 kg and now feels confident her habits are sustainable.
Dr. Al-Zubaidi emphasizes that exiting GLP-1 treatment safely requires guidance and long-term support. NICE recommends at least a year of tailored advice after stopping injections to help individuals maintain their weight and prevent relapse, as per BBC.
For patients paying privately, such structured support may not always be available, increasing the risk of regaining weight. Lifestyle, mindset, and environmental factors play a significant role in long-term outcomes.
Tanya has chosen to continue with her medication, aware of the pros and cons, while Ellen has closed that chapter and built a sustainable routine for life after Mounjaro.
Weight-loss jabs can dramatically change appetite and body weight, but stopping them can be challenging. The transition off these drugs requires careful planning, support, and lifestyle adjustments. As Tanya and Ellen’s experiences show, the journey varies by individual, and long-term strategies are essential to maintaining health and weight loss results.
Eli Lilly, the manufacturer of Mounjaro, states that patient safety is its top priority and that it continually monitors and reports information on treatment outcomes to regulators and prescribers.

Flu Symptoms: Seasonal infections are spreading across the United States just as the holiday travel rush gets underway, worrying health officials about fresh spikes during family get-togethers. Flu and norovirus cases are rising in several states, while COVID-19 continues to circulate at lower but consistent levels. Together, these illnesses are adding strain on hospitals as millions of people plan to travel in the days ahead.
“Super flu” is not a clinical term, but it is often used to describe a flu season that feels more aggressive or spreads faster than usual. This is typically linked to a dominant strain of influenza A. The current surge is being driven by a mutated influenza A strain known as H3N2 subclade K. Health officials say this strain has become the leading flu variant in the US, accounting for roughly 89 percent of H3N2 samples analysed since late September, according to genetic sequencing data from the Centers for Disease Control and Prevention (CDC).
This variant emerged after the 2025–26 flu vaccine was formulated, meaning the vaccine may not be as closely matched as in earlier seasons. While the shot still offers protection against severe disease, experts note that the mismatch could allow the virus to spread more easily.
The symptoms seen in the current flu wave are largely familiar. People may develop fever, chills, extreme tiredness, cough, and body aches. Doctors, however, caution that the wider spread could result in more serious cases, particularly among people who are at higher risk.
CDC estimates indicate that the US has already seen about 4.6 million flu cases this season, along with nearly 49,000 hospital admissions and around 1,900 deaths. Flu activity increased sharply in mid-December, with test positivity jumping from 8.1 percent to 14.3 percent within a single week.
Doctors recommend staying home when feeling unwell, washing hands often, especially to limit norovirus spread, and considering vaccination against flu and COVID-19. Even when the strain match is not ideal, experts stress that vaccines remain crucial in reducing the risk of severe illness, hospitalisation, and death.
In terms of how easily it spreads, it behaves much like regular flu, which is known to be highly contagious.
Someone with flu can pass on the virus from around one day before symptoms appear and continue to be contagious for five to seven days after becoming sick. Children, older adults, and those with weakened immune systems may remain infectious for a longer period.
The virus mainly spreads through respiratory droplets released when an infected person coughs, sneezes, speaks, or breathes near others. It can also spread through contact with contaminated surfaces, followed by touching the mouth, nose, or eyes. Crowded indoor settings, poor airflow, and close contact make transmission far more likely, which explains why flu spreads quickly during peak season.
What makes a so-called “super flu” seem more contagious is not a new way of spreading, but higher case numbers, quicker community transmission, and stronger symptoms, all of which increase coughing, fever, and the amount of virus released.

The NHS has urged people using a commonly prescribed medication to seek urgent medical advice if they notice any of three specific symptoms. These are linked to some of the more serious complications associated with dapagliflozin. Sold under the brand name Forxiga, dapagliflozin is mainly used to treat type 2 diabetes. It is also prescribed for people with heart failure and chronic kidney disease. While exact figures on how many prescriptions are issued each year in the UK are not publicly available, the drug is among the costliest for the health service, with NHS spending estimated at around £300 million a year in England alone.
Dapagliflozin belongs to a group of medicines known as SGLT2 inhibitors. It works by helping the kidneys remove excess glucose from the body through urine, which lowers blood sugar levels. Beyond diabetes, the drug has been shown to reduce the risk of hospitalisation in people with heart failure and slow the progression of chronic kidney disease. It may be prescribed on its own or alongside other treatments, depending on a patient’s condition and overall health.
Dapagliflozin can also be prescribed in combination with other diabetes medicines. These include Xigduo, which combines dapagliflozin with metformin, and Qtern, which pairs dapagliflozin with saxagliptin.
However, the NHS warns on its website that, “like all medicines,” dapagliflozin can cause side effects in some people. Patients are advised to “call your doctor or call 111 now” if they experience:
These reactions are classed as rare, affecting fewer than one in 10,000 people. More common side effects occur in over one in 100 users. The NHS says: “They’re usually mild and do not last long. There are things you can do to help cope with them.”
The NHS lists the following as more frequent side effects:
Taking dapagliflozin alongside other diabetes medicines, such as insulin or sulfonylureas like gliclazide, can sometimes cause blood sugar levels to drop too low. Some people may also develop diabetic ketoacidosis (DKA).
DKA happens when the body lacks enough insulin and harmful acids, known as ketones, build up in the blood. Warning signs can include nausea or vomiting, extreme thirst, confusion or severe tiredness, stomach pain, fruity-smelling breath, and fast or deep breathing. The NHS notes that symptoms usually develop within 24 hours, though they can appear more quickly.
Patients are taught how to monitor their blood sugar and ketone levels and what steps to take if symptoms appear. Emergency services should be contacted immediately by calling 999 if a person experiences a severe allergic reaction, known as anaphylaxis, after taking dapagliflozin.
