cord-270805-o6rbfmie	Hussein, Osama	Second wave of of Covid-19 is determined by immune mechanism	2020-09-02		.txt	text/plain	622	47	53	In this letter, the author describes an immunological explanation for the double-peaked epidemic curve of new viral diseases including Covid-19. This theory claims that a double-peaked pattern of new cases in a new viral epidemic is intrinsically determined by the pattern of pathogen interaction with the host. According to this hypothesis, relaxation of the community control measures is not responsible; at least in part, for resurgence of cases. Assuming the above hypothesis is true; a viral epidemic curve will show an early upstroke corresponding to persons who pass into viremia upon initial exposure to the virus followed by a second slower rise due to cases who develop the disease after repeated process of inoculation and clearance at the point of entry. In conclusion, the author describes an immunological explanation for a double-peaked epidemic curve of Covid-19 and other new viral diseases.	./cache/cord-270805-o6rbfmie.txt	./txt/cord-270805-o6rbfmie.txt
