What does it mean "aerosolised droplets" with referance to corona virus's spread? How it can b check
Aerosolised droplet/contact spread-(where disease transmission occurs because you touch a surface contaminated by these droplets, or get caught within the spray zone when the patient is coughing. Aerosols are so small that buoyant forces overcome gravity) aerosolized influenza A viruses are infectious at low doses, and tend to cause more typical influenza-like disease (fever plus cough), than intranasal inoculation which mimics contact and droplet transmission . Small droplets will remain in the air for very long periods of time (become airborne), but the exact cutoff is unknown, and can change significantly based on factors like temperature and humidity. With normal breathing, large droplets mostly fall to the ground within a 2 meter radius, but they can evaporate and become small droplets. Coughing and sneezing can propel these large droplets much further – at least 6 meters or 18 feet. COVID-19 can be spread through airborne aerosols,Because of their larger size, large droplets contain as much as 99.9% of viral particles exhaled. Although aerosols may carry small amounts of virus, they become very diffuse the further you are from the patient and are effectively managed by modern ventilation systems. I don’t think we should be making black and white statements. We need to consider the potential for aerosol spread, and how that might impact our PPE practices, while simultaneously recognizing that droplets and close contact with patients represent a far greater risk.

44-year-old male, stigmata of HIV, presented with shortness and respiratory distress. Patient was intimated and sedated. The patient is a known MDR-TB patient, on further investigation found to have completed treatment in 2015. Other history was not obtained. On arrival patient x/ray reviewed (attached - Image 1) and bilateral infiltrates noted as well as ? right lung mass. The patient sent for urgent non-contrast CTB (NAD) and chest. CT findings: ‘Basal infiltrates bilaterally, no cavities, faint effusions with no gross adenopathy. Active TB is very unlikely. Cardiomegaly with PAH. Paraseptal emphysema - mild degree only. Right pericardiac mass (mediastinal).” Patient management is ongoing. What are your valuable suggestions?

COVID-19?? 68 year old male with no significant past medical history or surgical history. Presented with shortness of breath, and chest pain. In the emergency department, the patient has a saturation of 79% on room air and is in Moderat respiratory distress. It requires 10 L of nasal oxygen high flow to obtain 93% oxygen saturation. The patient is also febrile to 101°F. Social history: non-smoker, non-drinker. Surgical history: no surgical history. What do you say about the case?

Coronavirus breakthrough as scientists discover Drug used to treat HEAD LICE can kill COVID-19 cells #CCU_CORONA =================================== updated 02:46 04 Apr 2020 Researchers at Monash University found Ivermectin can kills COVID-19 cells The anti-parasite drug killed off the cells within two days and is widely available Scientists are moving towards human trials but expect it to be at least a month Ivermectin has also been found to work against HIV, influenza and Zika virus An anti-parasitic head lice drug available around the world has been found to kill COVID-19 in the lab within 48 hours. A Monash University-led study has shown a single dose of the drug Ivermectin could stop the SARS-CoV-2 virus growing in cell culture. 'We found that even a single dose could essentially remove all viral RNA (effectively removed all genetic material of the virus) by 48 hours and that even at 24 hours there was a really significant reduction in it,' Monash Biomedicine Discovery Institute's Dr Kylie Wagstaff said on Friday. While it's not known how Ivermectin works on the virus, the drug likely stops the virus dampening the host cells' ability to clear it. The next step is for scientists to determine the correct human dosage, to make sure the level used in vitro is safe for humans. https://www.dailymail.co.uk/news/article-8186287/Monash-University-scientists-anti-parasite-Ivermectin-kill-COVID-19-cells-two-days.html
