tery life, however, continue to improve, more
sophisticated applications will be available via
mobile phones. It is the intention of the author
to enhance MPDDS to be able to incorporate

to enable faster and a more accurate diagnosis.
Increasing the speed of diagnosis will also serve
as a means of conserving the limited battery power
of these devices. Another challenge that needs to
be tackled in mobile devices is their small screen
sizes. Users with poor vision may have particular
problems using these devices, however, as the
screen sizes continue to improve, this limitation
would be eradicated.
CONCLUSION
Although various disease diagnosis systems have
been developed, they are either in the categories
of web-based and standalone applications. This
poses an accessibility problem for users in Africa in
general, and Nigeria in particular where computer
literacy and the ratio of computers to human are
