• Zika virus infection is a mosquito-borne disease caused by a flavivirus. This occurs in tropical countries with large mosquito population.
• Zika virus is transmitted to people through the bite of an infected mosquito from the Aedes genus, mainly Aedes aegypti in urban areas and Aedes albopictus in rural areas.
• Aedes bite aggressively during the day.
• This is the same mosquito that transmits Dengue and Chikungunya.
• Zika virus can also be transmitted through sex carrying Zika virus unprotected.
• Zika virus has been detected in blood, urine, amniotic fluids, semen, saliva as well as body fluids found in the brain and spinal cord.
Signs and Symptoms
• Common symptoms include fever, conjunctivitis, and skin rash.
• Other symptoms include headache, muscle pain, joint pain, pain behind the eyes, and vomiting.
• The illness is usually mild and self-limiting with symptoms lasting for 2-7 days.
• Neurological type of complication: Guillain-Barre’ syndrome which is the sudden weakening of muscles.
• Neonatal malformation: Microcephaly which is a condition where a baby’s head is smaller than those of other babies of the same age and sex.
Prevention and Treatment
• Avoid infection by preventing mosquito bites.
• Use insect repellants.
• Use window and door screens.
• Wear long-sleeved shirts and long pants or permethrin-treated clothing.
• Once a week, empty and scrub, turn over, cover, or throw out items that hold water such as tires, buckets, planters, toys, or trash containers.
• People sick with Zika virus should get plenty of rest, drink enough fluids and treat pain and fever with common medicines.
• People with signs and symptoms of Zika virus infection should undergo diagnostic test (serology)
• If symptoms persists, they should seek medical care and advice immediately to the nearest health facility.
