The websites of the World Health Organization (WHO), the Centers for Disease Control (CDC) and The National Vector Borne Disease Control Program of India (NVBDCP) provide updated information on dengue, its symptoms and treatment. Please consult the local doctor, health clinic or healthcare providers should one have a sudden onset of high fever and a painful headache and/or skin rash.

Dengue is spread by the Aedes mosquito, which prefers biting during the day time (sunlight hours). Even a single mosquito bite can lead to dengue. Thus it is important to protect loved ones, both indoors and outdoors, especially during the day. Before stepping out, the use of personal repellents like Goodknight Fabric Roll-On (or the Goodknight Cool Gel/Patches etc.) can prevent mosquito bites. When at home, shutting the doors and windows in the evening, and use of household-level repellents like Goodknight Activ+ and Goodknight Fast Card card even during the day will keep mosquitoes away.

Dengue can be diagnosed using laboratory tests to determine the presence of dengue antibodies (IgG and IgM) and through polymerase chain reactions (PCR) to determine the presence of the virus. Ideally, these tests must be done within the first few days of the patient presenting symptoms. The tests can be carried out at the local hospital or health clinic.

There is no specific treatment available for dengue; appropriate management of symptoms is crucial, especially maintaining an adequate volume of body fluids.

There is a commercially available vaccine against dengue, which is available in Mexico, Brazil, El Salvador and the Philippines. The WHO has not taken a formal position on the universal use of the vaccine, but has recommended that endemic countries should consider introduction of the vaccine into their national immunization programs. While there are several vaccine candidates currently under research and development worldwide, one should continue to take adequate precautions to prevent mosquito bites and dengue.

It is a severe flu-like illness beginning with a sudden onset of fever and painful headaches. Other symptoms include a skin rash, muscle and joint pain, nausea and vomiting. In extreme cases, it can lead to excessive bleeding (haemorrhaging) and death.

Dengue is a mosquito-borne disease caused by four different virus types, DENV 1-4, and spread by the Aedes mosquito. There are about 390 million dengue infections reported every year, of which 96 million exhibit symptoms. Today, about 3.9 billion people in over 128 countries are at risk for dengue.

There is no specific treatment available for chikungunya; appropriate management of symptoms is crucial. There is no commercially available vaccine against chikungunya.

The websites of the World Health Organization (WHO), the Centers for Disease Control (CDC) and The National Vector Borne Disease Control Program of India (NVBDCP) provide updated information on chikungunya, its symptoms and treatment. Please consult the local doctor, health clinic or healthcare providers should one have high fever along with sever joint pain and weakness.

Chikungunya is spread by the Aedes mosquito, which prefers biting during the day time (sunlight hours). Even a single mosquito bite can lead to chikungunya. Thus it is important to protect loved ones, both indoors and outdoors, especially during the day. Before stepping out, the use of personal repellents like Goodknight Fabric Roll-On (or the Goodknight Cool Gel/Patches etc.) can prevent mosquito bites. When at home, shutting the doors and windows in the evening, and use of household-level repellents like Goodknight Activ+ and Goodknight Fast Card card even during the day will keep mosquitoes away.

Chikungunya can be diagnosed using laboratory tests like enzyme-linked immunosorbent assays (ELISA) and reverse-transcriptase-polymerase chain reaction (RT-PCR) to detect the presence of the virus or antibodies to the virus. The tests can be carried out at the local hospital or health clinic. Please consult a doctor.

It is a flu-like illness with fever, headache and joint pain. Other symptoms include muscle pain, headache, body ache, nausea, fatigue and rash. Given the similarity between symptoms, chikungunya is often misdiagnosed as dengue. It is a chronic disease and once infected, a person can experience joint pain for extended periods of time even after the other symptoms disappear.

Chikungunya is a mosquito-borne disease caused by the chikungunya virus and spread by the Aedes mosquito. The disease is widespread in Africa, Asia and the Indian subcontinent.

Zika virus infection during pregnancy is a cause of microcephaly (smaller than normal head size) and other congenital abnormalities in the developing fetus and newborn. It can also result in complications such as fetal loss, stillbirth, and preterm birth.

There is no treatment in particular. However, the people infected with Zika Virus must get ample amount of rest, drink fluids to prevent dehydration, and take acetaminophen for fever and pain. If symptoms worsen, the patients should seek medical care and advice.

Zika virus can be transmitted from an infected mother to the fetus leading to birth defects. An estimated 5–15% of infants born to women infected with Zika virus during pregnancy have evidence of Zika-related complications. It can result in microcephaly (smaller than normal head size) and other congenital malformations in the infant, collectively referred to
as congenital Zika syndrome.

Zika virus is primarily transmitted by the bite of an infected mosquito. However, it can also be transmitted from mother to fetus during pregnancy, through sexual contact, transfusion of blood and blood products, and organ transplantation.

Take measures like wearing clothing (preferably light-coloured) that covers as much of the body as possible, use screens to cover windows and doors, sleep under mosquito nets, and eliminate stagnant water in and around your home to prevent mosquitoes.

Also, apply repellents like Goodknight Fabric Roll-On, Goodknight Cool Gel, Goodknight Patches before stepping outdoors. When at home, use repellents like Goodknight Activ+ and Goodknight Fast Card even during the day, to keep mosquitoes away.

The symptoms of Zika Virus are so common, that people fail to understand that they are infected with this disease. Symptoms include fever, rash, conjunctivitis, muscle and joint pain, malaise, and headache, which usually last for 2–7 days.

Aedes mosquitoes are usually active during the day, especially early mornings and late afternoons/evenings

Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes
