Table 3. Anopheles species prevalence by regions under current climate.

Geopolitical zone	Estimated Area (km2)	Mean Distribution Density per sq. km.			Prevalence (%)
		An. gambiae s.l.	An. gambiae s.s.	An. arabiensis	An. gambiae s.l.	An. gambiae s.s.	An. arabiensis
South South	68,888.90	1.38	1.29	1.29	69.10	64.46	64.65
South East	23,611.11	1.44	1.42	1.41	71.94	71.12	70.75
South West	61,666.67	1.43	1.57	1.59	71.29	78.28	79.70
North Central	186,388.91	1.24	1.30	1.25	61.75	64.85	62.51
North East	227,500.02	1.20	1.17	1.14	59.79	58.48	57.05
North West	177,222.24	1.34	1.20	1.18	67.16	60.07	58.95

Note: distribution density = 1km^-2 is equivalent to prevalence = 50% (species absence, designated with a green square); >1km^-2 ≡ >50% (species presence); and 2km^-2 ≡ 100% (maximum prevalence of species, designated with a red square).
