Since COVID-19 was first identified in December 2019 in Wuhan, China, researchers have been scrambling to learn more about the virus. The Centers for Disease Control and Prevention (CDC) lists fever\/chills, cough, shortness of breath\/difficulty breathing, fatigue, muscle\/body aches, headache, loss of taste\/smell, sore throat, congestion\/runny nose, nausea\/vomiting and diarrhea as possible symptoms; however, recent research shows that hearing loss may also be a lasting symptom of COVID-19.<\/p>\n

What the Research Shows \"woman<\/h2>\n

The first reported case of hearing loss caused by COVID-19 was published in the American Journal of Otolaryngology<\/em><\/a> at the beginning of April. According to the report, among the 82 cases of coronavirus in Thailand, one older female developed hearing loss that persisted even after her respiratory symptoms were gone. A research group in Turkey commented<\/a>, \u201cProbably, a neuro-auditory problem developed in the patient \u2026 Hearing loss in COVID-19 infection has never been reported in the literature so far\u201d on the original report.<\/p>\n

One week later, an Egypt study<\/a> of 20 asymptomatic COVID patients found decreased hearing abilities. These results were based on multiple auditory tests of patients 20-50 years old with no prior history of hearing problems. \u201cThe results of the current study showed that Covid-19 infection had deleterious effects on the hair cells in the cochlea \u2026 Moreover, the absence of the major symptoms does not guarantee a safe, healthy cochlear function,\u201d study authors explained.<\/p>\n

In June, an Iranian study<\/a> examined six COVID-19 patients with mild clinical symptoms whose ages ranged from 22 to 40. All patients had mild to moderate hearing loss in one ear, four had tinnitus (ringing in the ears) and two had vertigo (balance problems). None had previous hearing concerns. \u201cIt is highly likely that these otologic symptoms are directly related to\/caused by Covid-19,\u201d the Iran otolaryngologist concluded.<\/p>\n

Finally, a July study by Johns Hopkins<\/a> detected SARS-CoV-2 genetic material in the middle ear and mastoid bone in two of out of three deceased COVID-19 patients. \u201cThis study confirms the presence of SARS-CoV-2 virus in the middle ear and mastoid, with significant implications for otolaryngology procedures,\u201d explained the study authors.<\/p>\n
