How to get rid of the page break after the sections?

Question

I am very new to LaTeX and really only know how to use templates. I am making a LaTeX with the document class article that uses \include{} to put in the various sections in and it will start a new page after each section. I want to get rid of that. How do I do that?

This is my code

\documentclass[oneside]{article}
%
%% Based on a TeXnicCenter-Template by Gyorgy SZEIDL.
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{mathrsfs}
\usepackage{wrapfig}
\usepackage{lipsum}
\usepackage[margin=0.9in]{geometry}
\usepackage[affil-it]{authblk}




\begin{document}
\title{Awesome Title}
\author{student}
\affil{University}
\author{studen}
\affil{university}
\author{PI}
\affil{University}
\maketitle
\begin{abstract}
words
\end{abstract}

\include{intro}
\include{model}
\nopagebreak
\include{vaccReg}
\include{results}
\include{conclusion}
\appendix
\include{AppendixModel}
\include{methods}

\bibliography{MeaslesBibliography}
\bibliographystyle{apalike}

\end{document}

I hope this is enough information

Using \include is the same as \input with a \clearpage see This answer for more details.
