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.

Many people struggle to fall asleep because their minds race with worries about the next day or even old memories. To stop this mental chatter, some try complicated breathing exercises or relaxation hacks. However, a simple neuroscience trick involving temperature might help you drift off instantly.
Neuroscientist Kyle Cox suggests that you can fall asleep in seconds simply by placing something cold on your forehead when you go to bed. He explains that this method has been backed by sleep clinics and can be highly effective.
Researchers have learned that the temperature right on your forehead controls whether your brain stays active or decides to rest.
When the front part of your brain, called the frontal lobe, gets cooled down by even a little bit, just one degree, it automatically tells your body to start producing the chemicals needed for sleep.
The cold also quickly slows down all that busy mental chatter because the part of your brain that handles thinking (the prefrontal cortex) literally cannot work as hard when it is being cooled down.
A 2018 study published in the Sleep Journal also found similar results through a device that that cooled the forehead temperature as a treatment for insomnia. The device improved things like the time it took to fall asleep compared to the patient's own baseline sleep and the time it took to enter different stages of light and deep sleep (NREM Stages 1 and 2).
The two-night treatment helped patients fall asleep faster according to most PSG measurements and was safe. The researchers recommend more studies to see if this treatment works for the longer-term management of insomnia.
If you struggle with sleep, the NHS (National Health Service) says that often the best cure is to change your daily sleep habits. If you stick to a healthier routine, your insomnia usually gets much better over time.
Go to bed and set your alarm to wake up at the exact same time every day, even on weekends. This helps set your body's internal clock.
Start relaxing at least one hour before you plan to sleep. This could mean taking a warm bath, listening to calm music, or reading a physical book.
Make your bedroom a perfect place for sleeping. It should be as dark and quiet as possible. Use heavy curtains, blinds, or even an eye mask and earplugs if needed.
Exercise is great for sleep, but do it regularly during the day, not right before bed.
Check that your mattress, pillows, and blankets are supportive and cozy so you can easily relax once you lie down.
To sleep better, avoid things that keep you awake. Stop smoking, drinking caffeine or alcohol six hours before bed. Do not eat a large meal or exercise intensely late at night. Avoid screens right before bed, limit daytime naps, and always stick to your regular morning wake-up time.

Researchers have recently found that looking closely at the shape of the main buttock muscle, called the gluteus maximus, gives important clues about a person's health. This muscle shape reflects key changes linked to how we age, our lifestyle choices, and medical problems like diabetes.
This new study, done by a team at the University of Westminster, is unique because, unlike older research that only measured how big the muscle was, the team used advanced 3D mapping to show exactly where and how the muscle shape was changing.
These shifts, either the muscle shrinking (atrophy) or becoming inflamed, are connected to things like being frail, the amount of time someone sits each day, fat storage and diabetes risk.
the research analysed a large dataset, looking at over 61,000 MRI scans taken from the large U.K. Biobank health database.
Along with the MRI images, the dataset also included detailed information on 86 different factors for each person, including their medical history, body measurements, and what kind of lifestyle they led.
By putting all this data together, the team was able to figure out which specific factors were strongly linked to changes in the shape of the buttock muscle over time.
The analysis revealed strong connections between muscle shape and certain health factors:
People who were considered fitter, meaning they reported doing more vigorous physical activity and had a stronger hand grip, tended to have a greater gluteus maximus shape. This often means the muscle was larger and more defined.
On the other hand, factors like getting older, being generally frail (weak), and spending many hours sitting were all linked to muscle thinning or shrinkage. This suggests that a lack of use and the natural process of aging reduce the muscle's size and fullness.
A very important discovery was that the gluteal muscles don't change in the same way for men and women, especially when they are dealing with a disease. For example, men who were considered frail showed more shrinkage (thinning) in their gluteus maximus compared to women who were also frail.
When the researchers examined Type 2 diabetes, the difference was even more noticeable: diabetic men showed clear muscle thinning (reduced muscle mass), while diabetic women often showed enlarged muscle mass.
This larger appearance in women is likely due to fat building up within the muscle tissue, rather than the muscle itself growing stronger. These differences strongly suggest that the body's biological response to diseases like Type 2 diabetes may be completely different between men and women.
The researchers conclude that the shape of the buttocks, rather than simply its size, is more closely connected to fundamental metabolic changes happening in the body. Because the gluteus maximus is one of the largest muscles in the body, its health plays a crucial role in overall metabolic health.
These findings suggest that tracking gluteal muscle shape could potentially become a new way to monitor metabolic health and disease risk.

The NHS will not be automatically inviting all men above a certain age to check for prostate cancer, unlike the approach for some other cancers. The UK National Screening Committee has suggested that the prostate-specific antigen (PSA) test should only be actively offered to men carrying the BRCA gene mutation, which increases their risk. Still, men can request a PSA test from their GP in certain situations.
Olympic cycling hero Sir Chris Hoy, who has received a terminal diagnosis, is among those campaigning for men with known risk factors to be invited for a PSA test at a certain age, even if they do not have any symptoms.
A prostate-specific antigen (PSA) test checks the level of PSA in your blood. PSA is a protein produced by the prostate, a small gland in the male reproductive system located just below the bladder. The prostate produces the fluid part of semen.
The NHS says the test might be suggested if you notice symptoms that could point to prostate cancer, such as:
However, for most men, urinary symptoms are caused by something other than cancer.
A PSA test is usually carried out at a hospital or GP surgery by a nurse or other healthcare professional. Men are asked to avoid certain activities for 48 hours before the test, as these can temporarily raise PSA levels and affect the result. Activities to avoid include anything that leaves you out of breath, like strenuous exercise.
If a man’s PSA level comes back high, they may be offered a repeat test to see if the levels remain raised. If they do, the GP may refer them to a specialist for further investigations, such as a biopsy or an MRI scan.
PSA levels can rise for many reasons, including minor infections, and around 75% of men with a raised PSA do not have prostate cancer. A high reading can lead to referrals for unnecessary biopsies or MRI scans, or treatment for tumours that might never have caused harm.
The PSA test can also miss aggressive cancers. Research has shown that roughly 15% of men with a normal PSA result may actually have prostate cancer.
Routine PSA testing is not offered as standard on the NHS. You might be offered a test if a doctor suspects symptoms that could indicate prostate cancer. Men undergoing treatment for a prostate condition may be offered regular PSA checks to monitor how treatment is progressing.
Men aged 50 and over can request a PSA test from their GP, even without symptoms. Campaigners say many men are unaware that they are at higher risk of prostate cancer and should be actively encouraged to think about having a PSA check.
If the UK National Screening Committee’s recommendation is approved by the Government next year, men with the BRCA gene mutation could also be invited for a PSA test. Men who think a family member might have had the BRCA gene mutation can request a genetic test on the NHS to find out.
