Chikungunya

Although anyone can get chikungunya, certain factors increase the likelihood of infection or severity of the disease:

• Living in or traveling to areas where chikungunya is common or experiencing outbreaks.
• Residing in areas with inadequate mosquito control, such as places with stagnant water or poor sanitation.
• Spending time outdoors, particularly in areas with high mosquito activity, especially during the day around dawn and dusk when Aedes mosquitoes are most active.
• Being in regions with hot and wet conditions.
• Those who have never been infected with chikungunya before.
• Infants, young children, older adults, and individuals with weakened immune systems or other health conditions.

Ever wondered why mosquitoes seem to favor you over others?

You may have noticed that mosquitoes tend to bite you more than others. This could be due to factors like:

• Blood type O
• Mosquito-attracting genes
• Pregnancy
• Alcohol consumption

This happens because activities like drinking alcohol, being pregnant, or engaging in physical activity increase your metabolic rate, causing you to exhale more carbon dioxide, which attracts more mosquitoes.

Diagnosing chikungunya involves a combination of clinical evaluation and laboratory testing. The main steps in diagnosing chikungunya are as follows:

Medical History and Physical Examination

The healthcare provider will start by gathering a detailed medical history, including any recent travel to areas where chikungunya is common, as well as the symptoms you are experiencing. A physical examination will be conducted to identify signs of the disease.

Symptoms

Chikungunya is typically marked by symptoms such as a sudden high fever, joint pain, muscle aches, headaches, rashes, and fatigue. These symptoms overlap with those of dengue and Zika, so it is important to consider chikungunya, especially if these symptoms are present along with the patient’s geographical location.

Laboratory Tests

The most commonly used diagnostic tests for chikungunya include:

Reverse Transcription-Polymerase Chain Reaction (RT-PCR):

• This test detects the RNA of the chikungunya virus in a blood sample and is most effective in the first week of illness when the virus is replicating actively.

Antibody Tests:

• Also referred to as serological tests, these tests are used to detect antibodies in the bloodstream that develop after an infection. These tests typically employ methods like indirect immunofluorescence (IFA) or enzyme-linked immunosorbent assay (ELISA).

• The goal of these tests is to identify anti-chikungunya antibodies, specifically IgM (which can be detected from five days to weeks after infection) and IgG (which remains present from two weeks to several years post-infection).

• It is important to understand that antibody tests do not confirm a current infection but rather indicate past exposure to the virus.

Additional Tests

In many cases, a complete blood count (CBC) may be recommended. This test can provide valuable information about the severity of the infection and reveal other conditions, such as anemia, that may be related to the infection.

Currently, there is no approved vaccine for chikungunya.

Two vaccine candidates, one using a modified measles virus and another with virus-like particles, have completed initial trials. Further research and testing are in progress before these vaccines are approved for public use.

In the absence of a vaccine, the most effective way to prevent chikungunya is by taking precautions to avoid mosquito bites.

Preventive Measures to Avoid Mosquito Bites

• Wear long-sleeved shirts and pants when working outdoors, especially during the day, to minimize the risk of mosquito bites.
• Install screens on windows and doors to keep mosquitoes out of your home.
• Avoid outdoor activities during peak mosquito activity times.
• Use mosquito nets or screens around beds to create a barrier against mosquitoes.
• Consider using mosquito zappers, such as electric bats, to help control the mosquito population.
• Switch outdoor lights to yellow "bug" lights, as they tend to attract fewer mosquitoes than regular lights.
• Apply mosquito repellents containing DEET, picaridin, IR3535, Para-menthane-diol (PMD), or oil of lemon eucalyptus.

Pro Tip: Apply sunscreen first, then apply mosquito repellent.

Tips for Babies and Children

• Do not use products containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD) on children under 3.
• Avoid applying insect repellent to children's hands, eyes, mouth, cuts, or irritated skin.
• When applying repellent to children, adults should first apply it to their own hands and then use it on the child's face.
• After being indoors, wash 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 could accidentally inhale or get in their eyes.

Products for Preventing Mosquito Bites

• Mosquito repellent bands: These can be worn on the wrist and come in both chemical (DEET) and natural (essential oils) versions.
• Mosquito patches: Stick-on stickers for clothing (collars, sleeves, etc.), available in chemical and herbal varieties.
• Mosquito repellent body lotion or sprays: These may contain synthetic repellents like DEET or natural ones like citronella.
• Mosquito repellent sticks: Similar to incense sticks, these are used in outdoor spaces like gardens or balconies.
• Mosquito nets: A traditional option made of fine mesh for beds or window screens.
• Other products: Additional items like blankets, floor cleaners, electric zappers, and fumigation machines can help keep mosquitoes away.

Tips to Prevent Mosquito Breeding

• Avoid over-watering potted plants and empty the trays beneath them to prevent breeding grounds.
• Change water regularly in indoor plants and decorative items like bird baths, fountains, vases, and fish tanks.
• Empty water from trays under air conditioners, refrigerators, and other containers like pet bowls.
• Clean these containers every 15 days to interrupt the mosquito breeding cycle, which lasts around 15-20 days.
• When not in use, turn over empty buckets and cover containers with tight-fitting lids to stop mosquitoes from breeding.
• Use dustbins with lids and dispose of trash daily, as uncovered trash cans attract mosquitoes.
• Regular fogging with mosquito repellents or larvicides, and spraying pesticides like DDT in breeding areas, can help control mosquito populations.

Doctor to Visit

If you experience high fever accompanied by chills and live in an area with mosquito breeding, it’s recommended to consult a doctor. If you have a combination of symptoms such as high fever, joint pain, headaches, muscle aches, or a rash, seek medical care promptly.

Medical professionals who specialize in diagnosing and treating chikungunya include:

• General physician
• Internal medicine specialist
• Infectious disease specialist
• Pediatrician (for children and adolescents)

A general physician will examine your symptoms and may refer you to an internal medicine specialist if needed. Internal medicine specialists manage complex cases and address underlying health issues. Infectious disease specialists are crucial for diagnosing and treating infectious diseases like chikungunya. A pediatrician can provide care for children and adolescents, ensuring proper treatment and preventive measures.

The primary treatment for chikungunya fever focuses on symptom relief, including staying hydrated, resting, and using paracetamol to alleviate pain and fever. Treatment is generally divided into two phases:

Acute Phase

After an incubation period of 2 to 4 days, patients typically begin showing chikungunya symptoms, which may last for 3 to 7 days during the acute phase. The following treatment guidelines are usually recommended during this phase:

• Rest is essential, as physical activity can worsen joint pain, leading to increased wear and a prolonged recovery.
• Local measures such as cold compresses, ice packs, and pain relief gels can help reduce swelling and pain in the affected joints.
• Common medications used for mild to moderate pain include paracetamol and metamizole. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin are generally avoided due to their bleeding risk.
• For severe pain, paracetamol or metamizole may be combined with stronger opioids like tramadol.

Post-Acute Phase

While most individuals begin recovering within a week, some may experience persistent joint pain. If moderate to severe pain does not improve with current medications, additional treatments may be necessary. Disease-modifying antirheumatic drugs (DMARDs) such as methotrexate, hydroxychloroquine, or sulfasalazine may be considered.

• Once pain subsides, pain relief medications are discontinued. However, if pain persists, corticosteroids like prednisolone may be prescribed at an anti-inflammatory dose.
• Special care is taken in selecting medications for pregnant women and children.

While most people recover within a few weeks, individuals with pre-existing health conditions or weakened immune systems may face a higher risk of complications, including:

• Eye problems, such as conjunctivitis, optic neuritis, iridocyclitis, retinitis, and uveitis.
• Ongoing joint pain, potentially leading to chronic arthritis.
• Cardiovascular issues like myocarditis, pericarditis, and heart failure.
• Hepatitis, which involves liver inflammation.
• Skin issues, including fluid-filled blisters.
• Hemorrhage, which involves internal or external blood loss.
• Myelitis, or inflammation of the spinal cord.
• Cranial nerve palsies, which impair nerve function.
• Guillain-Barré syndrome, an autoimmune disorder affecting the nerves.

These alternative treatments should be used in combination with standard medical care and under the supervision of a healthcare provider. Some alternative therapies that may help include:

Physiotherapy:

Chikungunya can cause joint pain and stiffness. Physiotherapy exercises like gentle stretching and range-of-motion movements may aid in reducing severe pain and improving joint mobility associated with the disease.

Acupuncture:

Inserting thin needles into specific body points, acupuncture may help reduce pain and inflammation related to chikungunya. It is recommended to consult a licensed acupuncturist for this treatment.

Aromatherapy:

Essential oils, such as lavender, chamomile, and eucalyptus, may offer soothing and anti-inflammatory benefits. These oils can be used in a diffuser, added to a warm bath, or applied topically when diluted with a carrier oil. However, essential oils should be used cautiously and properly diluted to avoid skin irritation or other adverse effects.

Several herbal remedies may assist in managing chikungunya symptoms. It is important to remember that these remedies should not replace medical care or professional advice.

Below are some herbal options that may offer symptom relief for chikungunya:
