75 Time to leave

The window curtains had been drawn so as not to let sunlight pass inside the room. Julie laid in her bed with a blanket covering her and her eyes closed. A sudden cough broke through her lips, shaking and rattling her body and her breathing laboured. 

When she had woken up this morning, her head felt heavy and her eyes watery. She had been coughing since then, and she was running a fever. Melanie, who had come by her dorm earlier, had brought her breakfast. Julie had dismissed her friend to attend the classes, telling her she would be okay and she would rest in bed. 

But even though the food was here, it had been left on the table untouched. Julie wondered how she had fallen sick. 

"Achoo!" 

Why was she sneezing and coughing?!
