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.

Most people pay little attention to their knees, legs and ankles until something goes wrong. Once pain sets in, even simple things like walking, climbing stairs, or standing for long can become a real challenge. Left unmanaged, lower limb pain gradually affects mobility, independence and quality of life.
Knee pain commonly traces back to osteoarthritis, ligament injuries, cartilage damage, or years of wear. Pain in the leg can be caused by muscle injuries or conditions involving nerves and poor blood flow. The pain in the ankle is commonly caused by sprains, tendinitis, arthritis, or any injury that may have occurred earlier without complete healing.
Age, obesity, sedentary lifestyles, and constant joint injuries contribute silently to the degenerative condition of the joints.
Persistent pain, swelling, stiffness, or discomfort that keeps getting worse deserves attention. If pain is disturbing your sleep, that is a clear signal to see a doctor.
Walking downstairs puts considerable pressure on the knees, so limiting stair use where possible is sensible. Squatting, sitting on the floor and using Indian-style toilets place similar strain and are better avoided.
Staying active matters just as much. Regular household chores, walking, stretching and strengthening exercises, even 15 to 20 minutes a day, keep muscles strong and reduce the load on joints. Focusing on the adductor muscles around the knee is particularly effective in improving joint support.
Surgery is not always the answer. Two non-surgical treatments carried out by a pain physician can make a meaningful difference.
Platelet-Rich Plasma therapy, or PRP, involves concentrating platelets from the patient's own blood and injecting them into the affected joint. In osteoarthritis, where cartilage gradually thins, PRP may help support regeneration and ease symptoms.
Radiofrequency Ablation, or RFA, uses a specialized needle to deliver targeted heat that interrupts the nerves responsible for sending pain signals to the brain. Relief typically lasts one to two years. The procedure is done as day care with no cuts, no stitches and no anesthesia required.
A concern many patients raise is that pain stops them from exercising or losing weight. Once pain is controlled through these treatments, walking and light activity become manageable again, which in turn supports weight loss and takes further pressure off the joints.
Off-the-shelf knee caps have limited effectiveness. A custom-made support, designed to redistribute body weight and reduce joint stress, works considerably better, especially in early arthritis. Many patients notice relief shortly after wearing one. They are an investment, but a worthwhile one that can reduce dependence on medication while the surrounding muscles gradually strengthen.
If pain has lasted several weeks, is worsening, or is getting in the way of daily life, it is time to consult a specialist. Early diagnosis and the right treatment can protect joint function, restore mobility and often avoid the need for surgery.

Doctors in Mumbai are reporting a simultaneous rise in Covid-19, H1N1, commonly known as swine flu, and other respiratory viral infections.
As per the doctors, there is up to a 30 per cent surge in cases of COVID-19 and H1N1 as well as viral infections in the city. The doctors attributed the surge in infectious diseases to seasonal changes.
“We are currently observing a 20-30 per cent surge in Covid-19 and H1N1 (swine flu) respiratory viral infections in the city, mainly due to seasonal changes, increased humidity, and exposure to crowded places,” Dr. Aniket Mule, Consultant Internal Medicine, KIMS Hospital Thane, told HealthandMe.
Dr. Amit Saraf, Director of the Department of Internal Medicine, Jupiter Hospital, Thane, reported a rise in influenza-like illness (ILI) in the hospital.
“There is a seasonal rise in respiratory infection cases in Mumbai. Most of the people have routine viral infections, and around 10-15% of the people who are coming to OPDs have been coming positive for influenza-like illness (ILI) due to the changing weather,” Dr. Amit told HealthandMe.
Dr. Rohit Deshpande, Consultant Internal Medicine, Lilavati Hospital and Research Centre in Mumbai, told HealthandMe that the hospital is seeing a rise in swine flu cases.
“On average, 7 to 8 cases are being detected in the OPD daily. Most patients present with symptoms such as fever, cough, body ache, and fatigue”.

Dr. Amit noted that people with chronic illnesses, elderly people, pregnant women and young children are still more susceptible to complications.
Dr. Rohit noted that people with diabetes and those with conditions such as COPD, asthma and heart diseases are also at higher risk of infection.

The experts noted that most of the cases now are mild and can be handled with timely consultation, rest and supporting care.
But older people, pregnant women, children, and those with pre-existing health conditions should take extra care. Those with an ongoing fever, cough, sore throat, breathlessness, or extreme tiredness should seek immediate medical advice, Dr. Aniket said.
“Simple preventive measures like hand hygiene, use of masks in crowded places, proper hydration and timely medical consultation can help a lot in reducing the risk of complications,” he told HealthandMe.

The common perception about varicose veins is that they are merely an aesthetic or cosmetic problem. Varicose veins are indeed enlarged, twisted blood vessels that many people believe are not life-threatening. But the reality is that the condition may be a symptom of something more serious.
The disease manifests itself through insufficient blood supply in the body caused by faulty valves. As the blood vessels cannot effectively move the blood from the veins back to the heart, the blood tends to accumulate in the veins themselves. Other symptoms may include pain, heaviness, swelling, and skin sores in severe cases.
Varicose veins don’t develop overnight; they are usually the result of multiple underlying factors that gradually affect vein health and blood flow:
1. Valve dysfunction and poor circulation: Healthy veins rely on tiny valves to prevent backflow. When these valves weaken, blood starts collecting in the veins, leading to increased pressure and visible swelling.
2. Prolonged standing or sitting: These days, occupations require long hours of standing, which can hinder proper blood circulation and increase the risk.
3. Hormonal changes: Hormonal fluctuations during pregnancy, menopause, or while using hormonal therapies can relax vein walls, making them more prone to dysfunction.
4. Genetics: A family history of varicose veins significantly raises the likelihood of developing them, indicating a hereditary component in vein wall strength and valve efficiency.
5. Obesity and lack of physical activity: Excess body weight puts additional pressure on veins, while a sedentary lifestyle reduces the efficiency of blood circulation, leading to vein damage over time.
6. Ageing: As people age, veins lose elasticity, and valves may wear out, making older adults more susceptible to developing varicose veins.
People can manage or reverse varicose veins by:
Varicose vein treatment procedures have become much easier in the modern world. Varicose veins can now be treated with minimally invasive procedures that address the problem at its root cause. These minimally invasive treatments include EVLT (Endovenous Laser Treatment), Radiofrequency Ablation (RFA), and glue ablation. A laser fibre is inserted into the varicose vein during this operation, where it effectively closes it off.
Blood is automatically redirected through other veins after this treatment, which is relatively quick and involves local anesthesia. Patients generally recover within one day. However, EVLT is much less painful, safer, and does not involve leaving scars behind.
Varicose veins are often a symptom of vein disease and thus not just a cosmetic problem. They can be a visible sign of an underlying circulatory issue. Paying attention to early symptoms and seeking medical advice can help prevent complications and improve overall vascular health. Preventing further problems is easy when one knows what to do.
