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.

World Parkinson’s Day is observed every year on April 11 to raise awareness about the progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells.
People suffering from Parkinson’s face problems in motor movement, tremors, stiffness, and impaired balance. As symptoms progress, people may have difficulty walking, talking, or completing other simple tasks.
The condition primarily affects people over 60, but is now increasingly being seen in young adults. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety, and swallowing problems.
Parkinson's Day is observed on the day that marks the birthday of James Parkinson (born in 1755). The London-based doctor was the first to describe Parkinson as a medical condition in 1817, in his famous ‘Essay on the Shaking Palsy’. In 1997, the day was officially established by the European Parkinson’s Disease Association.
The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.
The day also aims to raise awareness about neurodegenerative diseases by educating the public about Parkinson's symptoms, causes, and available care.
Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.
According to a 2025 study released by The BMJ, this rise is mainly due to population aging and hence ranks as one of the most rapidly growing neurological disorders based on prevalence and disability. This alarming increase necessitates immediate global health interventions, research innovation, and policy reform to counteract its effects on people and health systems globally.
In addition, lifestyle differences, genetic susceptibility, and environmental exposures can also lead to regional variation in prevalence.
Parkinson's Disease affects various brain regions, but the primary symptoms arise from the degeneration of neurons in the substantia nigra, a region near the brain's base. This area is crucial for producing dopamine, a chemical messenger essential for smooth and purposeful movement. Research indicates that by the time Parkinson's symptoms become evident, patients have typically lost 60 to 80% or more of these dopamine-producing neurons.
Additionally, individuals with Parkinson’s disease experience a reduction in nerve endings that produce norepinephrine, a neurotransmitter responsible for regulating many involuntary bodily functions, such as heart rate and blood pressure. This loss may account for some non-movement-related symptoms of Parkinson’s, such as fatigue and fluctuations in blood pressure.
Though there is no cure for Parkinson's disease yet, studies indicate that some lifestyle elements have the potential to shape its incidence and progression.

Indian Actress Dipika Kakkar, battling liver cancer, underwent another surgery last month for a 1.3 cm cyst that reappeared.
Best known for her role as Simar Bhardwaj in the hit TV show Sasural Simar Ka, Dipika underwent a major tumour-removal surgery in June 2025. She also undertook chemotherapy
In her latest vlog, Dipika shared that the unexpected recurrence has left her feeling anxious and overwhelmed as doctors evaluate the next course of treatment.
"The recurrence that happened with the 1.3 cm cyst has shaken me. I am a little scared now that it shouldn't happen again. I have started dieting, but I feel anxious," she said.
HealthandMe spoke to health experts to understand why cysts recur in liver cancer patients and how it's important to keep monitoring them.
According to health experts, a biannual liver scan is imperative, and it can detect signs of cysts.
“Simple cysts less than 2-3 Cm can be observed with repeat scans every 6 months to 1 year. Suspicious or malignant cysts need surgical resection and oncological treatment based on the histopathology and patient condition,” Dr Manjunath NML, Sr Consultant, Surgical Oncology and Robotic Surgeon, HCG Cancer Hospital, K R Road, Bengaluru.
Liver cysts are like bags that are filled with fluid. They are usually not cancer. Most people who have liver cysts do not get cancer.
However, just because one has a cyst, it does not mean it's cancer.
“Cysts in the liver are typically harmless and unrelated to liver cancer. However, unusual types of cysts may suggest malignant changes that need further examination, particularly among risk groups,” Dr. Govind Nandakumar, Consultant – Gastrointestinal Surgery, Manipal Hospitals Hebbal, told HealthandMe.
The experts noted that cases of recurring cysts related to liver cancer are uncommon. But they occur because of

Many liver cysts do not cause any problems in the early stages. That is why regular check-ups with a doctor are important. If a cyst grows or becomes problematic, symptoms may begin to appear. These can include
Recurrent cysts can be effectively managed and treated over time. The recurrence does not necessarily imply the progression of the condition itself; however, more tests may be required to determine whether cysts are malignant or benign.
“Cysts with thick walls, septations inside, and solid components in them are more likely to be cancerous. If the cysts are large, they cause symptoms like pain, distension, and obstruction of the bowel or biliary tract,” Dr Manjunath said.
The experts explained that diagnosis can be achieved by scans like ultrasonography, Computerized Tomography CT or Magnetic Resonance Imaging (MRI). Suspicious cysts must be checked via biopsy to confirm malignancy.
While suspicious or malignant cysts require surgical resection and oncological treatment, symptomatic cysts, even if benign, may also require removal.
However, if a liver cyst is detected without suspicious features and is asymptomatic, it usually does not require any intervention, Dr. Manjunath noted.

What if the body whispers long before it screams? For many living with Parkinson’s disease, the earliest signs are not the tremors, but quieter changes, such as a diminished sense of smell, disrupted sleep, or gut problems. The challenge is that we are conditioned to look for the disease only once it becomes visible.
Parkinson’s disease, commonly referred to as a movement disorder, progresses slowly due to the destruction of the nerve cells in the brain.
To understand Parkinson’s disease, think of the brain as a command center where certain nerve cells produce dopamine, a chemical messenger that helps coordinate smooth movement. As these dopamine-producing cells gradually deteriorate, the brain’s signalling system gets disturbed, leading to slower movements, mistaken for normal ageing.
The majority of patients experience subtle early signs much before diagnosis, including a reduced sense of smell, sleep disturbances like insomnia, and persistent digestive problems like constipation. In these cases, timely intervention can reduce movement disability by roughly 40 percent.

Conventional treatment focuses on medications that boost dopamine levels, but over time, their effectiveness may decline. When drugs are no longer sufficient, doctors may recommend Deep Brain Stimulation (DBS), a surgical approach that works like a pacemaker for the brain and uses chest-connected electrodes to reset faulty signals causing stiffness and tremors.
Unlike fixed traditional stimulation, the advanced Adaptive DBS (aDBS) listens to brain signals in real-time to adjust therapy automatically. Its single threshold mode reacts instantly, boosting stimulation the moment brain signals hit a specific limit and turns it off just as fast once they improve.
Alternatively, its double threshold mode keeps stimulation steady within the safe zone," making only gradual tweaks if signals cross upper or lower limits. This smart system mimics the body’s natural rhythm to provide fluid symptom control while preventing overstimulation, ultimately helping you reclaim more "good" time and independence.
There is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.
Plant-based flavonoids, present in berries, citrus fruits, and broccoli, which have antioxidant effects, can help protect brain cells from damage. Drinking enough water can support digestion and prevent dehydration.
Ultimately, small, consistent dietary choices, combined with medical guidance, can make a meaningful difference in managing symptoms.
Parkinson’s disease is a journey, and the earlier the signs are recognized, the better the condition can be managed. If you or a loved one is experiencing persistent changes in sleep, smell, or movement, do not wait for the symptoms to become overwhelming. Consulting a neurologist is the first step toward taking back control of your health.
