Post-COVID condition is the presence of new, recurring, or ongoing signs and symptoms for greater than four weeks after a SARS-CoV-2 infection. Persistent headache as a neurologic sequalae of COVID-19 infection is a common prolonged symptom with limited characterization in the literature. This was a case of a 27-year-old female diagnosed with mild COVID-19 who presented with fever, colds, fatigue, headache, decreased hearing, sore throat, dry cough, pleuritic chest pain, anosmia, ageusia, myalgia, and severe low back pain. Headache was described as remitting, frontally located, squeezing and moderate to severe in pain intensity. She was admitted in a tertiary COVID referral hospital for 8 days and was managed supportively. On the 10th day of illness, symptoms had resolved except for an on and off headache. The residual recurrent headache lasted for more than 5 months after being tested negative for SARSCOV2 on repeat reverse transcriptase-polymerase chain reaction (RT-PCR). The possible pathophysiologic mechanisms for neurologic manifestations and prolonged headache were hypoxia, endothelial damage through angiotensin converting enzyme receptor, and cytokine reactions. The characteristics of the symptoms remained unclear despite the proposed mechanisms for prolonged headache among COVID-19 patients.

BACKGROUND: Because there is no specific treatment for the common cold, many previous studies have focused on prevention of the common cold. There were some studies reporting that regular, moderate-intensity exercise increases immunity and prevents the common cold. We conducted a meta-analysis to determine the effects of exercise on prevention of the common cold. METHODS: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL for studies released through June 2013. We manually searched the references. Two authors independently extracted the data. To assess the risk of bias of included literature, Cochrane Collaboration's tool for assessing risk of bias was used. Review Manager ver. 5.2 (RevMan, Cochrane Collaboration) was used for statistical analysis. RESULTS: Four randomized controlled trials were identified. A total of 281 participants, 134 in the exercise group and 147 in the control group, were included. The effect of exercise on the prevention of the common cold had a relative risk (RR) of 0.73 (95% confidence interval [CI], 0.56 to 0.95; I2 = 7%). The mean difference of mean illness days between exercise group and control group was -3.50 (95% CI, -6.06 to -0.94; I2 = 93%). In the subgroup analysis, the RR of under 16 weeks exercise was 0.79 (95% CI, 0.58 to 1.08). CONCLUSION: In this meta-analysis, regular, moderate-intensity exercise may have an effect on the prevention of the common cold. But numbers of included studies and participants were too small and quality of included studies was relatively poor. Subsequent well-designed studies with larger sample size are needed to clarify the association.

BACKGROUND: Probiotics are currently under focus for their immune improvement function. Many studies have been performed to assess the potential efficacy of probiotics in allergic disease, viral disease, respiratory disease, as well as gastrointestinal disease. This study performed a systematic review to determine the effects of probiotics on the prevention of the common cold. METHODS: We searched MEDLINE (PubMed), EMBASE, CINAHL, and Cochrane CENTRAL for studies released through June 2011. Two authors independently extracted the data. To assess the risk of bias of included literatures, Cochrane Collaboration's risk of bias tool was used. RESULTS: We identified 10 studies in 7 articles. A total 2,894 participants, 1,588 in the probiotics group and 1,306 in the control group, were included. The effect of probiotics on the prevention of the common cold had a relative risk (RR) of 0.92 (95% CI, 0.85 to 1.00, I2 = 26%). In the subgroup analysis, the RR of administration of probiotics for 3 months or less was 0.82 (95% CI, 0.70 to 0.97). The RR of administration of probiotics over 3 months was 1.00 (95% CI, 0.92 to 1.09). The RR of administration of probiotics without any active intervention (vitamin and mineral) was 0.87 (95% CI, 0.78 to 0.97). CONCLUSION: In this meta-analysis, there was marginal effect of probiotics on the prevention of the common cold. The results implied that probiotics had a modest effect in common cold reduction. The balance of benefit and harms needs to be considered when using probiotics for common cold prevention.

BACKGROUND: The purpose of our study was to assess the efficacy of influenza vaccination against influenza-like illness and the common cold in the elderly. METHODS: A total of 62 subjects, aged 60 years or older, were evaluated, who visited the Un-bong Welfare center, Bansong, Pusan. Attack rate of influenza-like illness and the common cold during winter, before and after influenza vaccination, was assessed by means of interview. RESULTS: After influenza vaccination, the attack frequency of influenza-like illness during winter was 0.07 0.31. This differed with 0.81 1.17 before vaccination (P<0.000). After influenza vaccination, the attack frequency of the common cold during winter was 1.22 1.61. This differed with 2.71 2.35 before vaccination (P<0.000). After influenza vaccination, the attack rate of influenza-like illness during winter was 45.2%. This differed with 4.8% before vaccination (P<0.000). After influenza vaccination, the attack frequency of common cold during winter was 87.1%. This differed with 48.4% before vaccination (P<0.000). The only side effect of influenza vaccination was pain (1.6%). CONCLUSION: In the elderly, influenza vaccination may reduce the incidence of influenza-like illness and the common cold during winter.
