Potential to develop a more effective cloth mask with finer weave, more layers and a better fit
‘The protection afforded by gauze masks increases with the fineness of the cloth and the number of layers, indicating potential to develop a more effective cloth mask, for example, with finer weave, more layers and a better fit.
‘Pandemics and emerging infections are more likely to arise in low-income or middle-income settings than in wealthy countries. In the interests of global public health, adequate attention should be paid to cloth mask use in such settings. The data from this study provide some reassurance about medical masks, and are the first data to show potential clinical efficacy of medical masks.’

Six points from Dr Amar Singh's article: ‘To understand our epidemic stop looking at daily Covid-19 numbers’
(2) The number tested positive (daily or cumulative) is dependent on the number of tests we conduct. Some modelling studies estimate the actual number in any country to be 10 times that.
(3) If we used death rate and assumed 1 death per 100, we would have 6,200 cases (as at April 6) but this figure is distorted by other factors. E.g. we could have missed out counting Covid-19 among other pneumonia cases. Pneumonia accounts for 11.8% of deaths in Malaysia or 390 per week.
(4) There are two lag times that affect the figures: (a) First, “it takes about 7-14 days before an infected person presents clinically. It takes another 7-14 days before illness severity and dying (ventilation and ICU care).” (b) Second, there is a backlog of testing. “Some say it takes 5-7 days to get results. Even health care staff that have potentially been exposed may have to wait for 4-5 days to get their status known.”
(5) We have community spread: “From MoH Influenza-Like Illness (ILI) & Severe Acute Respiratory Infection (SARI) surveillance that is conducted at selected sites, about 1.2 per cent of these patients have been Covid-19 positive in the past week. This indicates community spread, as these persons have no contact with known cases. We do not know how many patients with pneumonia and severe respiratory illnesses (influenza-like illness) we have missed in the past 4-6 weeks.”
Point 5 justifies a lockdown because, given community spread, gatherings of people could become “transmission amplification events”.
(6) We need to do more to protect our front-line workers. “Many staff have had to rely on homemade (not all reliable) or donated PPE. We are still struggling with the distribution of national PPE supplies. Even as far back as March 20, MoH reported that 15 HCPs had been infected by Covid-19 as part of their work.”

Nurses. Nurses. Nurses
“Among the nine countries with the highest number of Covid-19 cases, the country that has the highest nurse rate also has the lowest death rate from the disease. Germany has 13.2 nurses per 1,000 (echoing a trend for high nurse numbers throughout Northern Europe) far above the other heavily Covid-19 affected countries.
“This may be just another armchair epidemiologist observation of course. But higher numbers of nurses may reflect one of two beneficial factors (or both): first, that nurses, the backbone of hospital (and especially ICU) care, are essential to patient management and, ultimately, survival.
“The second is that the sort of hospital or country that knows the value of nurses also is a hospital or country that understands how to deliver effective health care and has likely made countless other unmeasured adjustments to improve quality.”
