How do mosquito nets prevent malaria?
All mosquito nets act as a physical barrier, preventing bites by vector mosquitoes and thus providing personal protection against malaria to the individual(s) using the nets. ITNs (like all nets) reduce contact between the person and mosquito by acting as a physical barrier.
How effective are ITNs?
Insecticide-treated nets reduce child mortality from all causes by 17% compared to no nets (rate ratio 0.83, 95% CI 0.77 to 0.89; 5 trials, 200,833 participants, high-certainty evidence). This corresponds to a saving of 5.6 lives (95% CI 3.6 to 7.6) each year for every 1000 children protected with ITNs.
How do you treat mosquito nets?
Mix one dose of insecticide with water to treat one net of any size. Be sure to use only those insecticides that are recommended for mosquito nets. Do not wring too hard – as when washing clothes – or you will lose the insecticide. Later, you can also hang up the treated net to finish drying.
How effective are insecticide treated mosquito nets?
Insecticide‐treated nets reduce child mortality from all causes by 17% compared to no nets (rate ratio 0.83, 95% CI 0.77 to 0.89; 5 trials, 200,833 participants, high‐certainty evidence). This corresponds to a saving of 5.6 lives (95% CI 3.6 to 7.6) each year for every 1000 children protected with ITNs.
How is malaria prevented?
To lower your chances of getting malaria, you should:
- Apply mosquito repellent with DEET (diethyltoluamide) to exposed skin.
- Drape mosquito netting over beds.
- Put screens on windows and doors.
- Treat clothing, mosquito nets, tents, sleeping bags and other fabrics with an insect repellent called permethrin.
What is mosquito netting used for?
Insecticide-treated mosquito nets are used to cover the place in which a person sleeps to prevent mosquitos from biting them. The nets are provided widely, often at low-cost or even free. The World Health Organization says access to the nets helped reach a drop in malaria deaths.
How do LLINs work?
Long-lasting insecticidal nets, or LLINs, have significantly reduced malaria morbidity and mortality over the past two decades. The net provides a physical barrier that decreases human-mosquito contact and the impregnated insecticide kills susceptible mosquito vectors upon contact and may repel them.
Where are mosquito nets used?
Usage. Mosquito nets are often used where malaria or other insect-borne diseases are common, especially as a tent-like covering over a bed. For effectiveness, it is important that the netting not have holes or gaps large enough to allow insects to enter.
Which insecticide is used in mosquito net?
These nets are dip-treated using a synthetic pyrethroid insecticide such as deltamethrin or permethrin which will double the protection over a non-treated net by killing and repelling mosquitoes. For maximum effectiveness, ITNs should be re-impregnated with insecticide every six months.
What are the three potential ways to control malaria?
The main current measures are focused on reduction of the contact between mosquitoes and humans, the destruction of larvae by environmental management and the use of larvicides or mosquito larvae predators, and destruction of adult mosquitoes by indoor residual spraying and insecticide-treated bed nets.
