Coronovirus – realistic optimism from Chinese experience – Dr Bruce Aylward, WHO

Dr Bruce Aylward also was on an Australian webinar on 6/3/20 – recording here.

2 March 20:30 GMT — Transmission details emerge from WHO China analysisCOVID

China has mounted “perhaps the most ambitious, agile and aggressive disease containment effort in history” against a new infectious disease, the World Health Organization (WHO) said in a report released on 28 February, after a 9-day meeting in China, 16–24 February. The report analyses data from the outbreak in China, and recommends steps that China and other countries should take to curb COVID-19.

New daily cases are declining in the country, the WHO confirmed, so much so that authorities are now having problems recruiting patients for the more than 80 clinical trials being run there that test potential treatments for the coronavirus. Some experimental treatments should be prioritized over others, the health agency recommended.

The report’s analysis of data from China finds that 104 strains of the coronavirus, named SARS-CoV-2, collected from people between December 2019 and mid-February 2020 are 99.9% similar, meaning that the virus is not significantly mutating. The median age of people infected is 51 years old. And most cases that have spread from person to person are within hospitals, jails or households, which implies close contact is often required for the virus to spread between people. Airborne spread is not believed to be a major driver of transmission, the report says. In one preliminary study from the province of Guangdong, people who shared the same household as someone with COVID-19 had 3–10% chance of being infected.

The WHO credits China’s ability to reign in the epidemic to a variety of measures. One is that 1,800 teams of epidemiologists have rapidly tracked tens of thousands of contacts of people infected with the virus in the Hubei province, where the outbreak emerged. Up to 5% of these contacts ended up having the disease and were diagnosed quickly. And the report says the lockdown on travel out of Hubei — an unprecedented measure in a province of this size — curbed wider spread of the disease to China’s 1.4 billion citizens.

Quality microbiological diagnostics and antimicrobial susceptibility testing explained

Our recent ‘Lessons from the Field’ paper is now (freely) available via the Western Pacific Surveillance and Response journal It is focused on implementation of quality testing in Pacific Island nations. 

Clinicians and others may be interested in the answers to these questions which are seldom explained:

  • How does quality microbiological culture and AST enable better patient care?
  • What are the meanings of minimum inhibitory concentration and clinical breakpoints?
  • How is AST usually performed?
  • What challenges occur with AST?
  • What are recent AST data from Pacific Nations showing about AMR?

Local production of alcohol hand rub for hospital use (WHO guidance)

Here is excellent straightforward WHO guidance required to set up a cost-effective production facility within an LMIC hospital. Commercial product will usually cost 5-10 times the price.

Hand hygiene by staff before and after every patient interaction is one of the key ways in which to save lives from hospital acquired infection.  If you need to know more, read about Ignaz Semmelweis, the father of infection control who first demonstrated that disinfecting hands saved lives in 1840s Vienna or see one of the references below.

Staphylococcus aureus complex – S. argenteus – bug of the week

Guest posting from Dr Dan Lennon, Microbiology Registrar, Pathology North.

This species is increasingly recognised now that MALDITOF  mass spectrometry is widely used for bacterial identification. Here is a useful short summary : S argenteus Lennon 2019 Sept. These species should be regarded as clinically equivalent to S. aureus.

Here is a beautiful  photo taken by Dan. Staphylococcus argenteus on the left. S. aureus on the right. Chocolate agar.

Cryptocococcal infection bibliography – PNG and Cambodia

I have assembled bibliographies of Cryptococcal literature relevant to:

Two PNG PhD theses of relevance date from the 1990s – summaries here – the authors published several papers that are within the collection above:

Rapid testing of serum and CSF using the current ICT card tests is a reliable diagnostic measure for both C. neoformans and C. gattii.  See also –

I have not located literature relevant to other Western Pacific Nations. Please let me know if anything is located.
