Is Blood-C set in the same world as Blood+?


I know that Blood-C was produced in-part by Studio Production I.G, the
creators of Blood+, and it has a lot of similarities to Blood+, such as the
appearance and name of the characters and the name of the manga/anime/film.
Are they set in the same world or in some sort of parallel universe, or is
Blood-C something like a reboot of Blood+?

Blood+




As given on [Wikia](http://bloodc.wikia.com/wiki/Saya_Kisaragi) :

> Saya Kisaragi has long hair that are similar to that of original Saya
> Otonashi, respectively of Blood+ in 1863 early version of Saya and 1972
> Vietnam War in scenes only.
>
> Despite major dissimilarities other than that they are different
> personalities, between the two Saya's of Blood+ and Blood-C, such as their
> backstory and traits for the character; they share the similar plot
> differently. For Example Saya Kirasagi sings when walking around town and
> the Other Saya Otonashi plays the cello but badly judging from the reactions
> of other characters.
>
> Somehow Saya Kirasagi remains in mystery where she come from despite of her
> origins, unlike Blood+ Saya Otonashi comes from a chiropteran mummy
>
> Saya never calls a sword in the series except in the opening when she mind
> controls her cover of the sword even as Tadayoshi Kirasagi gives the sword ,
> before battles like Blood+ Saya from Haji and The Last Vampire from David.

It seems to be of a parallel or a totally different world because of the
various differences shown in spite of the similarities introduced to make it
of a series.
