I'm sure when we get rapid tests the numbers for testing would skyrocket.

My same partner, whose father is in ICU, his entire immediate family of 5 waiting for results 3 weeks now and he was told to self quarantine. He has done his part and stayed at home. He is waiting for a "fit to work" paper and can't get it yet. For the 3 weeks, only 3 calls were received to ensure he "staying home".
Thankfully he and his family is ok

saw a similar post from someone on facebook.
went in for a other issue not covid, doctor decided to do the test and play safe even tho some symptoms was hit and miss
wrote 14 day sick leave, at the end of the sick leave, the results was lost or the test itself IDK but had to retake one and wait another 14 days. I still following this and would update once i get some info.
madness.
could imagine the workplace tho? people prob freaking out

Something is definitely going wrong there. And with positivity rates over 20% since that day with the miraculous 1600 completed tests we definitely have a big problem.

Visualizing droplet dispersal for face shields and masks with exhalation valves
Several places across the world are experiencing a steep surge in COVID-19 infections. Face masks have become increasingly accepted as one of the most effective means for combating the spread of the disease when used in combination with social-distancing and frequent hand-washing. However, there is an increasing trend of people substituting regular cloth or surgical masks with clear plastic face shields and with masks equipped with exhalation valves. One of the factors driving this increased adoption is improved comfort compared to regular masks. However, there is a possibility that widespread public use of these alternatives to regular masks could have an adverse effect on mitigation efforts. To help increase public awareness regarding the effectiveness of these alternative options, we use qualitative visualizations to examine the performance of face shields and exhalation valves in impeding the spread of aerosol-sized droplets. The visualizations indicate that although face shields block the initial forward motion of the jet, the expelled droplets can move around the visor with relative ease and spread out over a large area depending on light ambient disturbances. Visualizations for a mask equipped with an exhalation port indicate that a large number of droplets pass through the exhale valve unfiltered, which significantly reduces its effectiveness as a means of source control. Our observations suggest that to minimize the community spread of COVID-19, it may be preferable to use high-quality cloth or surgical masks that are of a plain design, instead of face shields and masks equipped with exhale valves.

Pan-American Health Organization (PAHO) director of the Department of Communicable Diseases Dr Marcos Espinal said TT is still not testing as much as it should.
He was speaking during TTT’s NOW morning show on Tuesday.
Espinal said Mauritius in East Africa, which has a population comparable to TT, has done over 200,000 tests, as compared to TT’s almost 24,000. “It is important to increase the testing because otherwise we will not know what the magnitude of the problem is. Another example is Costa Rica which has created mobile teams to ensure people who are isolated are followed properly to make sure they received their medicines, food and they are taken care of by family or relatives.
This is because you don’t have to hospitalise everyone, it is important as there are best practices and PAHO is willing to assist.”
The testing rate in TT is currently at five per cent. Up to July 20, before the current spike in covid19 cases began, 4,557 unique samples had been tested in the public health system, from which 137 people had tested positive. This totalled three per cent of tests done. As of Tuesday morning, 20,729 tests had been carried out, of which 1,063 samples had tested positive. This totalled 5.13 per cent of tests done. In March, the WHO said between three and 12 per cent of tests have been positive in countries where extensive testing has taken place.
World Health Organization (WHO)/PAHO Rep for TT and the Dutch Kingdom Islands Dr Erica Wheeler, also speaking on the NOW morning show, said the antigen tests announced by the health minster on Monday would assist in the ramping up of testing. PAHO is assisting the government in purchasing the testing kits.
“What PAHO is assisting the country to do is to decentralise the testing, to make it easier for people to go to the primary care level, meaning to their clinics, and be tested there, so this is going to make a great difference. We call it a “game-changer,” these antigen tests, because the turn-around time is going to be very quick. Between 15 and 30 minutes you can have a test done, and this will make a really big difference in being able to ramp up the testing, not just in district hospitals and in Couva and Caura, but also in the clinics, so that’s really important.”
The new rapid antigen test kits cost US$6 each and will be an investment of US$960,000 for TT. The new technology gives the capacity to do antigen testing that has an all-round accuracy of 95 per cent.

A PCR swab test costs US$100 to US$200. The newest Abbott antigen test costs US$5 and processes in 15 minutes.redmanjp wrote:I think the regular PCR test is much more expensive but more accurate.
But the antigen test are very cheap so they should expand testing with these tests. Test all asymptomatic persons who are contacts of positive cases.
Also test anyone requiring a test for medical reasons like surgery dental procedures etc.
