The proximity required of a thorough biomicroscopic slit-lamp examination may put ophthalmologists at increased risk for respiratory-borne infection with SARS-CoV-2. Conjunctivitis has been described in a few patients with COVID-19 and other coronavirus syndromes. Although SARS-CoV-2 has been detected in the conjunctival secretions or tears of patients with COVID-19 and conjunctivitis, transmission of infection through respiratory droplets to ophthalmologists without eye protection or masks may be the bigger concern.
This letter examines healthcare worker deaths by category and medical speciality during the COVID-19 emergency in Italy, and underlines factors that may have contributed to the elevated number of fatalities among healthcare personnel. These data are now available because Italy was the first western country to be severely affected. These are matters for urgent discussion as development goes forward.
In the current absence of vaccine for COVID-19, public health response target breaking the chain of infection by focusing on the mode of transmission. This paper summarizes current evidence-base around the transmission dynamics, pathogenic, and clinical features of COVID-19, to critically identify if there are any gaps in the current IPC guidelines.
Methods
This study involved a review of global COVID-19 IPC guidelines such as WHO, the CDC, and European Centre for Disease Prevention and Control (ECDC). Guidelines from two high income countries (Australia and UK) and one middle income country (China) were also reviewed. We searched publications in English on ‘Pubmed’ and Google Scholars. We extracted information related to COVID-19 transmission dynamics, clinical presentations and exposures that may facilitate the transmission and compared and contrasted these findings with the recommended IPC measures.
Results
The review findings showed nosocomial transmission of SARS-CoV-2 in health settings through droplet, aerosol and by an oral-fecal or fecal-droplet route. However, the IPC guidelines fail to cover all transmission modes and the recommendations also conflict with each other. Most guidelines recommend surgical masks for healthcare providers during routine care and N95 respirators for aerosol generating procedures. However, recommendations around type of surgical masks varied. In addition, CDC recommends cloth masks when the surgical mask is totally unavailable.
Conclusion
IPC strategies should consider all the possible routes of transmission and target all patient care activities where there may be person to person transmission risk. This review may assist international health agencies to update their guidelines.
The current Covid-19 pandemic is not just a medical and social tragedy, but within the threat of the outbreak looms the potential for a significant and persistent negative mental health impact, based on previous experience with other pandemics such as SARS in 2003 and the earlier H1N1 outbreak of 1918. This piece will highlight the links between depression and viral illnesses and explore important overlaps with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, potentially implicating inflammatory mechanisms in those exposed to a range of viral agents. While containment of psychological distress currently focuses on social anxiety and quarantine measures, a second wave of psychological morbidity due to viral illness may be imminent.
The impacts of the COVID-19 pandemic affect all groups in society. People with intellectual disability are especially vulnerable to the physical, mental and social effects of the pandemic. Cognitive impairments can limit understanding of information to protect them relying on carers to be vigilant on their behalf during quarantine. Restrictions on usual activities are likely to induce mental stress especially among those who are autistic leading to an escalation in challenging behaviours, risk of placement breakdown, and increased the use of psychotropic medication. People with intellectual disability are vulnerable to exploitation by others where the usual community supports no longer function to protect them. In future pandemics, it is important that lessons are learned from the impacts COVID-19 has on people with intellectual disability. Collecting the evidence through a rigorous approach should help to empower people with intellectual disability and their carers to face future outbreaks of infectious diseases
