31. - Female mosquito feeds on blood-for egg
production.
- Roughly three days after feeding, the mosquito
lays eggs in several locations over multiple days.
- A single female -100 eggs per blood feed
- Produce up to five batches
(in her one to two-week lifetime)
• Aedes aegypti eggs - stay dormant for over six

42. Immunoglobulin G or IgG / IgM
• IgG -Antibody that is found most abundantly
in the human body.

48. Prevention
No vaccine can protect
against dengue fever.
Only avoiding mosquito
bites can prevent it.
10/9/2017 48Meston College of Education- Chennai

49. • Clothing: Reduce the amount of skin exposed by
wearing long pants, long sleeved shirts, and socks,
tucking pant legs into shoes or socks, and wearing a
hat.
• Mosquito repellents: Use a repellent with at least 10
percent concentration of diethyltoluamide (DEET), or a
higher concentration for longer lengths of exposure.
Avoid using DEET on young children.
• Mosquito traps and nets: Nets treated with insecticide
are more effective, otherwise the mosquito can bite
through the net if the person is standing next to it. The
insecticide will kill mosquitoes and other insects, and it
will repel insects from entering the room.
10/9/2017 49Meston College of Education- Chennai

50. • Door and window screens: Structural barriers, such
as screens or netting, can keep mosquitos out.
• Avoid scents: Heavily scented soaps and perfumes
may attract mosquitos.
• Camping gear: Treat clothes, shoes, and camping
gear with permethrin, or purchase clothes that
have been pretreated.
• Timing: Try to avoid being outside at dawn, dusk,
and early evening.
10/9/2017 50Meston College of Education- Chennai

51. • Stagnant water: The Aedes mosquito breeds
in clean, stagnant water. Checking for and
removing stagnant water can help reduce the
risk.
10/9/2017 51Meston College of Education- Chennai

52. • To reduce the risk of mosquitoes breeding in stagnant water:
• turn buckets and watering cans over and store them under shelter so that
water cannot accumulate
• remove excess water from plant pot plates
• scrub containers to remove mosquito eggs
• loosen soil from potted plants, to prevent puddles forming on the surface
• make sure scupper drains are not blocked, and do not place potted plants
and other objects over them
• use non-perforated gully traps, install anti-mosquito valves, and cover any
traps that are rarely used
• do not place receptacles under an air-conditioning unit
• change the water in flower vases every second day and scrub and rinse the
inside of the vase
• prevent leaves from blocking anything that may result in the accumulation
of puddles or stagnant water
• When camping or picnicking, choose an area that is away from still water.
