WHO emphasizes, both people who show symptoms of illness, such as cough, flu or fever, or those who do not show symptoms or are asymptomatic.
This was followed by the update guidelines Centers for Disease Control and Prevention ( CDC) United States, linked testing which there is no need to do when people might be exposed to Covid-19 from positive people.
As reported CNN, Wednesday (26/8/2020), change CDC guidelines it is thought to confuse doctors.
Because, in the Covid-19 testing guidelines, the CDC said a few people without symptoms may not need to be tested, if they have been in close contact with someone who is infected with the virus.
ER doctor and professor of public health at George Washington University, Dr Leana Wen, said the changes to testing guidelines submitted by the CDC did not make sense.
“It is precisely these (people who are suspected of being exposed to Covid-19) who should be tested,” said Dr Wen.
These changes to guidelines, according to a senior federal health official, are the result of pressure from the administration of US President Donald Trump.
Regarding coronavirus testing guidelines, the CDC website previously wrote that testing is recommended for all close contact of people with viral infections SARS-CoV-2. Due to the potential for asymptomatic and pre-symptomatic transmission that may occur.
However, on Monday, the guidelines were updated, stating that if a person has close contact with a distance of 1.5-2 meters with someone who is infected with Covid-19, for at least 15 minutes but has no symptoms, there is no need for testing.
Unless a vulnerable person or health care provider, or local public health official recommends getting tested.
In response to this, the WHO Covid-19 technical leader, Maria Van Kerkhove did not mention the specific US situation, as reported from Science Alert quoted from AFP, Friday (28/8/2020).
WHO has recommended that if there is contact with someone who is confirmed positive for Covid-19, then if possible a test is carried out, regardless of the development of symptoms experienced.
“We know that people who have symptoms can be contagious, and we know that people who don’t have symptoms can also transmit the virus,” explained Van Kerkhove.
Guidelines The handling of this global pandemic by WHO has been developed, and has delegated the authority for testing strategies to each country.
Data on positive cases of the SARS-CoV-2 virus in the world based on Worldometer currently has reached more than 24.6 million cases, with a death rate of 835,679 cases.
Van Kerkhove said the focus of Covid-19 testing is on those who experience symptoms, especially when investigating groups of cases, so testing may need to be expanded.
“Most importantly, the test is used as an opportunity to find active cases, so that they can be isolated and can also be done contact tracing. This is very important to break the chain of transmission (corona virus transmission), “he explained.
