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.

Persistent back pain in young adults is often dismissed as poor posture, long hours at a desk, or muscle strain. But doctors are warning that in some cases, it could be a sign of ankylosing spondylitis — a chronic inflammatory autoimmune disease that affects the spine and can silently progress for years before diagnosis.
In India, 16.5 lakh people suffer from the condition, with an average diagnostic gap of nearly seven years from the time symptoms first appear. During that window, the disease continues to silently progress, and the burden is far from small.
“Ankylosing Spondylitis is one of the most underdiagnosed conditions we encounter in clinical practice, and the consequences of that delay are real,” Dr. Arvind Mehra, Senior Director and HOD - Orthopaedics at Paras Health Gurugram, told HealthandMe.
Moreover, “It takes several years of pain and stiffness before people seek treatment, and by then, the diagnosis comes too late, and there has already been damage to the spine,” added Dr. Ashish Tomar, Director - Orthopaedics & Minimally Invasive Spine Surgery at Sarvodaya Hospital, Faridabad.
Ankylosing spondylitis, also known as axial spondyloarthritis, is a type of arthritis that primarily targets the spine but can also affect other joints. The term “ankylosing” means stiff or rigid, “spondyl” refers to the spine, and “itis” indicates inflammation.
The inflammatory disease causes some of the bones in the spine to fuse over time. This fusing not only makes the spine less flexible but can also cause issues while breathing.
Ankylosing spondylitis leads to inflammation in the spine and large joints, causing stiffness and pain. It can also impact the joint between the spine and the hipbone, potentially resulting in additional symptoms such as digestive issues, rashes, and weight loss.
What makes ankylosing spondylitis difficult to spot is that it often feels like ordinary back pain — but there are warning signs that set it apart.
According to experts, ankylosing spondylitis-related pain typically:
This pattern is very different from mechanical back pain, which usually worsens with movement and improves with rest.
Dr. Tomar told HealthandMe that ankylosing spondylitis is not simply a musculoskeletal problem — it is an autoimmune disease, where the body’s immune system mistakenly attacks healthy tissues, particularly around the spine and joints.
“Ankylosing spondylitis is not just another musculoskeletal disease. It requires the attention given to autoimmune disorders because it may affect the chest, hips, shoulders, and even the eyes, while also causing severe posture problems in advanced stages,” he said.
Beyond the spine, the disease may affect:
Who Is At Most Risk? How To Treat?
Young adults, typically in their twenties, are more likely to experience this condition because people often overlook its existence or mistakenly identify it as something else.
The combination of early diagnosis, structured physiotherapy, and suitable medications allows for effective disease progression control.
“When a young adult presents with inflammatory back pain, especially in the gluteal area, that persists beyond three months, the reflex should not be to prescribe a painkiller and wait. It should be investigated further. That shift in approach can make an extraordinary difference to someone’s long-term quality of life,” Dr. Tomar said.
Common treatments for ankylosing spondylitis include:

When women are in their 40s, their bodies start to change a lot because of the hormones. This is mainly because the estrogen and progesterone levels in the body start to go down. This time is called Perimenopause.
It is when women start to move towards menopause. It can bring a lot of emotional changes. Some of these changes are normal.
After 40, women's bodies start to produce estrogen. This means they can have an imbalance.
Women's bodies need hormones like estrogen and progesterone to have periods, strong bones, a good mood, and to stay at a healthy weight. When these hormone levels change, it affects parts of the body. This change can take a year before it stops at menopause.
Common hormonal changes women experience
While some changes are normal, some symptoms need a doctor's help:
When women are over 40 and their hormones change, they are more likely to have:
Estrogen helps keep the heart and bones healthy, so when its levels go down, women are more likely to have these health problems."
Women should talk about these changes openly. If they know what is happening and see a doctor early, they can make this time easier.
Hormonal changes after 40 are a part of getting older, but women should not ignore them. Especially if the symptoms are very bad or happen all the time.
If women understand what is happening in their bodies and see a doctor when they need to, they can be healthier and more confident. If women take care of themselves now, they can have a life in the years to come.

The US Food and Drug Administration (FDA) has approved tradipitant to be sold under the brand name Nereus, for the prevention of vomiting induced by motion in adults — a first in the last four decades.
Motion sickness affects an estimated 65 to 78 million Americans—roughly 25 to 30 percent of adults—during everyday travel by car, plane, or boat. For decades, patients have had no meaningful new treatment options.
Tradipitant is an oral neurokinin-1 (NK-1) receptor antagonist that prevents motion-induced vomiting in adults.
It is an oral capsule, often taken 60 minutes before travel to block signals causing nausea.
The drug by Vanda Pharmaceuticals is now commercially available across the US.
"Today marks an important milestone for the tens of millions of Americans who experience motion sickness symptoms during common travel," said Mihael H. Polymeropoulos, M.D, President, CEO, and Chairman of Vanda, in a statement.
Motion sickness occurs when the brain receives conflicting signals from the eyes, inner ear, and body while in motion. This sensory mismatch is believed to trigger the release of substance P, which activates NK-1 receptors in the central nervous system and ultimately leads to nausea and vomiting.
Tradipitant works by blocking these receptors, interrupting the vomiting pathway.
"NEREUS is a selective, high-affinity antagonist of human substance P/neurokinin-1 (NK-1) receptors that can block the vomiting center of the brain,” Polymeropoulos said.
Tradipitant was approved by the FDA, following two pivotal Phase 3 clinical trials—Motion Syros and Motion Serifos—conducted under real-world conditions on the open sea.

Both studies demonstrated that tradipitant significantly prevents vomiting compared to placebo, confirming the drug's effectiveness in actual sea travel conditions. It is the first new prescription option for people with a history of motion sickness in over 40 years.
It employs a novel mechanism as a selective, high-affinity antagonist of human substance P/NK-1 receptors. It offers simple dosing with just one or two capsules a day taken approximately an hour before travel.

According to Vanda Pharmaceuticals, tradipitant may impair abilities required for driving a motor vehicle or operating heavy machinery.
Combining tradipitant with sedatives or medications that increase the drug's levels may increase this effect. If use together cannot be avoided, your doctor may warn against driving or operating heavy machinery.
The most common side effects associated with tradipitant include drowsiness, headache, and fatigue.
Moreover, strong CYP3A4 inhibitors may increase NEREUS™ levels and the risk of side effects, the company said.
There are limited data on tradipitant's use in pregnant women and children.
Tradipitant is also not recommended in patients with liver problems or severe kidney problems.
