伤寒第一天，足太阳经受邪。太阳经，是膀胱的经脉，为三阳经之首，所以最先受病。其脉络联系腰脊，主司肌肉之间，因此可以通过涂抹药膏、火灸等方法发汗而痊愈。凡是五脏功能不和，六腑气机不通，营卫运行阻滞，在这种情况下经过三天就会死亡。
（原文此处有脱漏或错简，根据上下文及《伤寒论》常理，此处应指“第二日”或承接上文，但原文仅存“何满”二字疑似衍文或误植，且后文直接接“其脉循于胁...故得病三日”，结合中医理论，第三日通常涉及少阳经。此处依原文字面翻译，但需注意逻辑断层）：其脉循行于胁肋，上行至颈部和耳朵。所以患病第三天，会出现胸胁发热和耳聋的症状。三阳经的经络开始相互传变，病邪尚未进入脏腑，可以通过发汗的方法解除。
伤寒第四天，足太阴经受邪。太阴经，是脾的经脉，为三阴经之首。因此，在三天之后，阳经受病完毕，病邪传入阴经，太阴经受邪。其脉络联系脾脏，主司咽喉。所以患病第四天，会出现腹部胀满和咽喉干燥的症状。病位在胸膈，因此可以通过催吐的方法而痊愈。
伤寒第五天，足少阴经受邪。少阴经，是肾的经脉。其经脉贯穿肾脏，联络肺系，连接于舌根。所以患病第五天，会出现口热、舌干、口渴想喝水的症状。病位在肠，因此可以通过泻下的方法而痊愈。
伤寒第六天，足厥阴经受邪。厥阴经，是肝的经脉。其脉循行阴部络于肝脏。所以患病第六天，会出现心烦腹满和阴囊收缩的症状。此时阴阳两经都受病，毒邪在胃，可以通过泻下的方法而痊愈。
第七天，太阳病势衰退，头痛轻微好转。另外，伤寒第七天，病情应当有所减轻，这是因为阴阳各经的传变过程已经结束。如果在七天以后病情反而加重，这是将要发生“再经病”（病邪再次传遍一经）。所谓再经病，是指经络再次受邪。
伤寒第八天，阳明病势衰退，身体发热轻微好转。如果八天后病仍未解，可能是因为诸阴阳经络再次受邪，或者是因为在发汗、催吐、泻下之后，毒邪未尽，所以病症仍然存在。
伤寒第九天，少阳病势衰退，耳聋症状轻微缓解，能听到一点声音。另外，如果伤寒九日以上，病邪未除，可能是因为触动了一经受邪，则不能继续相传；或者已经传遍三阳经，而不能传入阴经，导致停滞数日，病症不解，日子久了，病候就会发生改变。
On the first day of cold damage (Shanghan), the Foot-Taiyang meridian is affected. The Taiyang meridian belongs to the Bladder, and as the head of the three Yang meridians, it is the first to be affected. Its collaterals connect to the waist and spine, and govern the space between muscles and skin; therefore, it can be cured by applying ointments or using moxibustion to induce sweating. If the five Zang organs are disharmonious, the six Fu organs are obstructed, and Ying (Nutrient) and Wei (Defensive) Qi fail to circulate, death may occur after three days under such conditions.
[Note: The original text contains apparent textual corruption ("He Man") before describing the Shaoyang pattern. Based on standard Shanghan Lun theory, this section describes the third day.] The meridian courses along the hypochondrium and ascends to the neck and ears. Thus, on the third day of illness, there is heat in the chest and hypochondrium accompanied by deafness. The meridians of the three Yang stages begin to transmit sequentially; since the pathogen has not yet entered the Zang organs, it can be resolved through diaphoresis (sweating).
On the fourth day of cold damage, the Foot-Taiyin meridian is affected. The Taiyin meridian belongs to the Spleen and is the head of the three Yin meridians. Therefore, after the completion of the three-day cycle affecting the Yang meridians, the transmission moves to the Yin, and the Taiyin meridian becomes affected. Its collaterals connect to the Spleen and govern the throat. Thus, on the fourth day, abdominal fullness and dryness of the throat occur. Since the disease location is in the chest and diaphragm, it can be cured by emesis (vomiting).
On the fifth day of cold damage, the Foot-Shaoyin meridian is affected. The Shaoyin meridian belongs to the Kidney. Its channel penetrates the Kidney, connects with the Lung system, and links to the root of the tongue. Thus, on the fifth day, there is heat in the mouth, dryness of the tongue, thirst, and a desire to drink water. Since the disease location is in the intestines, it can be cured by purgation (downward draining).
On the sixth day of cold damage, the Foot-Jueyin meridian is affected. The Jueyin meridian belongs to the Liver. Its vessel courses through the yin regions and connects to the Liver. Thus, on the sixth day, there is vexation, abdominal fullness, and retraction of the genitals. At this stage, both Yin and Yang meridians are affected, and toxic pathogens reside in the Stomach; it can be cured by purgation.
On the seventh day, the Taiyang disease begins to recede, and the headache improves slightly. Generally, on the seventh day of cold damage, the condition should show slight improvement because the transmission through the Yin and Yang meridians has reached its conclusion. If the condition worsens after the seventh day, it indicates a "re-transmission" (Zai Jing Bing), meaning the meridians have been affected again.
On the eighth day, the Yangming disease begins to recede, and body heat subsides slightly. If the condition persists beyond eight days, it may be due to repeated infection of the various Yin and Yang meridians, or because toxic pathogens remain incomplete after previous treatments such as sweating, vomiting, or purging; thus, the symptoms persist.
On the ninth day, the Shaoyang disease begins to recede, and deafness slightly improves, allowing for faint hearing. If the condition remains unresolved after nine days, it might be because one meridian was disturbed and transmission ceased, or because the transmission through the three Yang meridians was completed but failed to enter the Yin, causing stagnation for several days. Consequently, the disease lingers, and the clinical manifestations change over time.
On the tenth day, the Taiyin disease begins to recede; the abdomen and stomach return to normal, and appetite returns.
On the eleventh day, the Shaoyin disease begins to recede; thirst ceases, vexation and abdominal fullness disappear, and dryness of the tongue resolves.
On the twelfth day, the Jueyin disease is cured; retraction of the scrotum and lower abdominal distension subside, all toxic pathogens are eliminated, and the course of the disease concludes.
