Symptoms of the disease last for several days to a week. During pregnancy, zika is seen to cause serious birth defect microcephaly and other congenital malformations, known as congenital Zika syndrome.

Prevention from Mosquito-causing diseases

  • Several precautions can be taken to prevent these vector-causing diseases such as the use of insecticide-treated nets (ITNs), mosquito repellents like the Good Knight Activ+ System, and indoor residual spraying (IRS).
  • Elimination of mosquito breeding by covering all water containers, emptying and drying water tanks, containers, coolers, bird-baths etc. i.e., discarding items that collect rainwater from open spaces, check the clogged gutters and flat roofs that may have poor drainage.
  • Introducing larvivorous fishes in ornamental water tanks/gardens or nearby ponds can help prevent diseases.
