Chikungunya

The symptoms of chikungunya typically appear 2 to 12 days after a person has been bitten by an infected mosquito. The most common symptoms of chikungunya include:

• Abrupt onset of fever or chills
• Severe joint pain and swelling
• Joint stiffness
• Knee pain
• Shoulder pain
• Muscular pain
• Headache
• Nausea
• Rashes and redness of the skin
• Fatigue or tiredness
• Abnormal bleeding tendency
• Skin blistering

Chikungunya is a viral disease transmitted to humans through the bite of infected mosquitoes, primarily the Aedes aegypti and Aedes albopictus species.

When an uninfected mosquito bites a person infected with the Chikungunya virus (CHIKV), the virus enters the mosquito's body. After a few days, the virus spreads to the mosquito's salivary glands.

When the mosquito bites another person, the CHIKV enters the bloodstream and spreads throughout the body, infecting various tissues, including:

• Muscle cells
• Immune cells

In the new host, the virus multiplies and reaches high levels in the blood, causing symptoms of chikungunya.

The virus can enter the body through:

• The skin
• Respiration
• Ingestion
• Sexual contact (vaginal, oral, anal)
• Transmission to an unborn baby through the placenta or birth canal

The virus primarily targets cells in the joints, leading to inflammation and severe joint pain.

While anyone can contract chikungunya, the following risk factors may increase the likelihood of infection or the severity of the disease:

• Staying or traveling to regions where chikungunya is endemic or experiencing outbreaks.
• Living in areas with inadequate mosquito control measures, such as stagnant water sources or poor sanitation.
• Spending time outdoors, especially in areas with high mosquito populations. Mosquito exposure is more likely during the daytime, particularly around dawn and dusk when Aedes mosquitoes are most active.
• Wetter and hotter months of the year.
• Individuals who have not been previously infected with chikungunya.
• Infants, young children, older adults, and individuals with weakened immune systems or underlying health conditions.

Ever wondered why mosquitoes prefer biting you over others? There might be times when you have wondered why mosquitoes bite you more than others. Well, this could be because of:

• 'O' Blood type
• Mosquito-attracting genes
• Pregnancy
• Consumption of alcohol

The rationale behind this is that alcohol consumption, pregnancy, and even physical activity raise your metabolic rate, causing you to exhale more carbon dioxide, which in turn attracts more mosquitoes.

The diagnosis of chikungunya involves a combination of clinical evaluation and laboratory tests. Here are the key steps involved in diagnosing chikungunya:

1. Medical history and physical examination
   The healthcare provider will begin by taking a detailed medical history, including information about recent travel to regions where chikungunya is prevalent and symptoms you may be experiencing. A physical examination to check for signs of the disease will also be performed.
2. Symptoms
   Chikungunya is characterized by symptoms such as sudden onset of high fever, joint pain, muscle pain, headache, rash, and fatigue. These symptoms can be similar to those of dengue and Zika, making it important to consider the possibility of chikungunya based on the presence of symptoms and the geographical location.
3. Laboratory Tests
   The most commonly used tests for the diagnosis of chikungunya include:
   • Reverse Transcription-Polymerase Chain Reaction (RT-PCR): This test detects the genetic material (RNA) of the chikungunya virus in a blood sample. It is most effective during the first week of illness when the virus is actively replicating.
   • Antibody tests: Also known as serological tests, these are designed to identify the presence of antibodies in the bloodstream, which typically develop after an infection. These tests employ either indirect immunofluorescence (IFA) or enzyme-linked immunosorbent assay (ELISA) methods. The purpose of these tests is to detect the presence of anti-chikungunya antibodies, specifically IgM (which is detectable from five days to several weeks after infection) and IgG (which remains present from two weeks to several years after infection). It's important to note that antibody tests do not detect current infections but indicate previous exposure to the virus.
4. Other tests
   In most situations, it is advisable to undergo a complete blood count (CBC). This can provide your doctor with information about the severity of the infection and the presence of other conditions like anemia caused by the infection.

Presently, there is no approved vaccine for the prevention of chikungunya.

Two vaccine candidates, one made from a modified measles virus and another using virus-like particles, have completed initial tests. More research and trials are underway before the vaccine is approved for public use.

In the absence of a vaccine, the most effective way to avoid chikungunya is by taking measures to protect yourself from mosquito bites.

1. Preventive measures to avoid mosquito bites

• Wear long-sleeved shirts and long pants when working outdoors during the day to reduce the risk of mosquito bites.
• Install window and door screens to keep mosquitoes out of your living areas.
• Avoid outdoor activities during times when mosquitoes are most active.
• Use mosquito nets or screens around beds to create a barrier against mosquitoes.
• Consider using mosquito zapping devices, such as electric bats, to control the mosquito population.
• To minimize mosquito attraction, switch your outdoor lights to yellow "bug" lights. While not repellent, these lights tend to attract fewer mosquitoes compared to regular lights.
• Apply mosquito repellents that contain DEET, picaridin, IR3535, para-menthane-diol (PMD), or oil of lemon eucalyptus.

Pro Tip: Apply sunscreen before applying mosquito repellent.

2. Tips for babies and children

• Do not use products containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD) on children under the age of 3.
• Avoid applying insect repellent on a child's hands, eyes, mouth, cuts, or irritated skin.
• When using insect repellent for children, adults should first spray it onto their own hands and then apply it to the child's face.
• After returning indoors, wash your children's skin with soap and water to remove any repellent, and wash their clothing before they wear it again.
• Avoid using sprays in pressurized containers that children may accidentally inhale or get into their eyes.

3. Products for preventing mosquito bites

• Mosquito repellent bands: Worn on the wrist, they come in chemical (DEET-impregnated) and natural (essential oils) varieties.
• Mosquito patches: Stickers that can be attached to clothes (collars, sleeves, skirts, shorts) available in chemical and herbal forms.
• Body lotion or mosquito sprays: Synthetic repellents (DEET, permethrin) or natural repellents (citronella) for protection.
• Mosquito repellent sticks: Similar to incense sticks, loaded with repellents, used in open spaces like gardens, terraces, or balconies.
• Mosquito nets: Conventional option with fine wire mesh (18 x 18 strands per inch) for beds or window screens.
• Additional repellent products: Apart from these repellents, there are products like blankets, floor cleaners, electric zappers, and table-top fumigation machines, which help keep mosquitoes away.

4. Tips to prevent mosquito breeding

• Avoid excessive watering of potted plants and ensure that trays are emptied to prevent them from becoming breeding grounds.
• Regularly change the water for indoor plants and decorative items that can collect water, such as bird baths, tabletop fountains, flower vases, and fish tanks.
• Empty water from trays under air conditioners, refrigerators, and other containers like pet or bird feeding bowls.
• Clean these containers at least once every 15 days to disrupt the mosquito breeding cycle, which typically lasts around 15-20 days.
• When not in use, turn over empty pails and buckets, and cover containers with tight-fitting lids to prevent mosquitoes from breeding.
• Use dustbins with properly fitting lids and dispose of trash daily, as uncovered trash cans attract mosquitoes.
• Implement regular fogging with mosquito repellents or larvicides, and consider spraying pesticides like DDT in potential mosquito breeding areas.

The main treatment for Chikungunya fever focuses on relieving symptoms, such as drinking enough fluids, resting, and using paracetamol for pain and fever relief. The treatment can be broadly divided into two phases:

1. Acute phase

After a silent incubation period of 2 to 4 days, patients generally display chikungunya symptoms that may persist for 3–7 days during the acute phase of the disease. The following treatment protocols are usually followed during this phase:

• Rest is one of the main recommendations, as physical activities tend to aggravate joint pain, contributing to local wear and prolonging the clinical condition.
• Certain local measures, such as the application of cold compresses or ice packs and pain relief gels to the affected joints, can reduce swelling and pain.
• The two most commonly used medications for mild to moderate pain are paracetamol and metamizole. NSAIDs like ibuprofen and aspirin are usually avoided due to the risk of bleeding.
• In cases of severe pain, paracetamol or metamizole may be combined with opioids like tramadol.

2. Post acute phase

While most patients start showing signs of recovery after a week, chronic and incapacitating joint pain can persist in some cases.

In cases of moderate to severe pain that does not respond satisfactorily to current medications, other drugs may be recommended. Options include disease-modifying antirheumatic drugs (DMARDs) such as methotrexate, hydroxychloroquine, or sulfasalazine.

Once the pain subsides, pain relief medications are suspended; conversely, if the pain persists, corticosteroids like prednisolone may be prescribed at an anti-inflammatory dose.

Note: Special considerations are made for pregnant women and children regarding medication choices.

Diet for better recovery from Chikungunya

• Consume nutrient-rich foods: Include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats in your diet. These foods provide essential nutrients, antioxidants, and fiber to support your immune system and promote overall well-being.
• Increase intake of anti-inflammatory foods: Chikungunya can cause joint pain and inflammation. Include foods with anti-inflammatory properties in your diet, such as turmeric, ginger, garlic, berries, leafy greens, fatty fish (like salmon and mackerel), and nuts.
• Include foods rich in vitamins and minerals: Foods that are high in vitamin C, vitamin D, vitamin E, and zinc can help boost your immune system. Citrus fruits, berries, kiwi, bell peppers, spinach, nuts, seeds, and legumes are good sources of these nutrients.
• Focus on healthy fats: Include sources of healthy fats like avocados, olive oil, nuts, and seeds in your diet. These fats have anti-inflammatory properties and can support your overall health.
• Limit processed foods and added sugars: Minimize your consumption of processed foods, sugary snacks, and beverages as they can weaken the immune system and promote inflammation.
• Probiotics: Probiotics such as yogurt, pickles, and tempeh (fermented soybeans) are rich in good bacteria that support gut health and help stimulate the immune system to fight off disease.

Other tips that can help in alleviating symptoms:

• Stay hydrated: Drink plenty of fluids such as water, herbal teas, and fresh fruit juices to stay hydrated and help flush out toxins from your body. Proper hydration makes it easier for immune-boosting nutrients to reach the cells in your body.
• Take proper rest: Get plenty of rest to allow your body to recover and conserve energy. Avoid strenuous activities that may worsen your symptoms.
• Epsom salt baths: A soothing bath with Epsom salt is a commonly used home remedy for various conditions, including muscle aches and pains. Dissolve about two cups of Epsom salt in a bathtub filled with warm water and soak for 15-20 minutes. This may provide temporary relief and help relax the muscles.
• Cold compresses: Applying cold compresses or ice packs to swollen joints or areas of pain can help reduce inflammation and provide temporary relief from discomfort.

Most individuals with chikungunya experience a self-limiting illness and recover within a few weeks. However, individuals with pre-existing health conditions or weakened immune systems may be at a higher risk of developing the following complications:

• Eye issues such as conjunctivitis (inflammation or infection of the conjunctiva), optic neuritis (swelling of the optic nerve), iridocyclitis (inflammation of the iris), retinitis (inflammation of the retina), and uveitis (inflammation of the uvea).
• Persistent joint pain.
• Chronic arthritis (long-term joint inflammation that leads to chronic arthritis).
• Cardiovascular issues such as myocarditis (inflammation of the heart muscle), pericarditis (inflammation of the pericardium), and heart failure.
• Hepatitis (liver inflammation).
• Skin lesions (fluid-filled blisters).
• Hemorrhage (loss of blood, inside or outside the body).
• Myelitis (inflammation of the spinal cord).
• Cranial nerve palsies (loss of function of a nerve).
• Guillain-Barré syndrome (an autoimmune disorder affecting the nerves).
