How Fast Does Omicron BF.7 Spread?
How Fast Does Omicron BF.7 Spread: Due to Omicron BF.7, the world is facing a new wave of Corona. Omicron BF.7 has spread to more than 100 countries. Omicron BF.7 spreads many times faster than the delta variant that has wreaked havoc on the world.
According to a study, a person infected with Omicron BF.7 becomes a corona spread faster than the previous variants. That is, it takes very little time for the Omicron BF.7 infected person to spread corona to other people. Or simply say that an Omicron BF.7 infected person becomes a virus-spreading zombie within 24 hours.
Omicron BF.7 has an R0 value of 10 to 18.6. That is, a person infected with this variant can infect 10 to 18 people on average. WHO officials believe that it is the highest among all variants so far. Earlier the R0 value of Delta was 6-7 and the R0 value of Alpha was 4-5.
In China, 800 million people may get corona infected in the next few months. The high R0 value of BF.7 in China may also be due to the weak immunity of the Chinese. Due to the zero covid policy, the immunity of the people of China is not as strong as the rest of the world.
Symptoms Appear Quickly in Omicron BF.7 Infected Person
According to the US Federal Health Agency Disease Control and Prevention (CDC), any corona-infected person is most contagious a few days before symptoms appear and a few days after the symptoms are over.
However, according to some experts, in the case of Omicron BF.7, the person is becoming infectious or the corona spread faster than other corona variants.
The Risk of Spreading Corona Remains Even After The Symptoms Are Over
According to the US Health Agency CDC, a person infected with any variant of corona remains most infectious or spreads the coronavirus for a few days before and a few days after the symptoms arise.
Omicron BF.7 is causing symptoms quickly (in about 3 days) as compared to other variants, in such a situation a person can become a corona spreader in just a day.
On the other hand, the Omicron BF.7 infected person can remain a corona spreader for a few days (two-three days) after the onset of symptoms.
Symptoms from Delta and other variants were being produced in 4-5 days and with these variants, the person was becoming a corona spreader in 2-4 days.
Even with earlier variants of Omicron BF.7, the person is at risk of remaining contagious for a few days after symptoms appear.
The Incubation Period of Omicron BF.7 is Just 3 Days
The speed of its spread is known only by the incubation period of the virus. Actually, the time between a person coming in contact with a corona-infected person and the onset of symptoms is called the incubation period.
As per the studies, the incubation period of the delta variant was 4 days and that of the alpha was 5 days. At the same time, it is believed that the incubation period of BF.7 has reduced to 3 days.
According to experts, there is every possibility that the shorter the incubation period of a virus, the faster it is likely to become contagious and the faster the pandemic will spread.
The short incubation period makes any virus very difficult to control, according to epidemiologist Jennifer Nuzzo of the Johns Hopkins Center for Health Security.
This is the reason that a person of BF.7 is becoming a corona spreader faster than other variants.
Dr. Amy Kargar of the University of Minnesota Medical School has said about the short incubation period of BF.7 that most people are getting positive on the third day.
This suggests that Omicron is more susceptible to infection with BF.7 than other variants.
Even Asymptomatic People Are Contagious
There are studies on whether a corona-infected person is symptomatic, that is, those who are causing symptoms, becoming contagious, or becoming a corona spreader.
Most patients with Omicron BF.7 are asymptomatic, meaning they do not develop symptoms despite being infected. In such a situation, the question arises in how many days do asymptomatic people become corona spreaders?
Experts believe that most asymptomatic people have a low viral load or its level. In such a situation, it is not clear how quickly they become corona spreaders.
However, according to the WHO, the risk of spreading corona from a corona-infected person without symptoms, that is, from an asymptomatic person, remains the same as from a person with symptoms.
That’s why it is important that if you have recently come in contact with a corona person, even if you are not showing any symptoms, you should get the corona test done.
This is because it is possible that you are not showing symptoms, but you have been infected with the coronavirus. If this happens then the risk of spreading this virus to others through you will increase.
According to the guidelines of the Ministry of Health, asymptomatic people coming corona positive should also isolate themselves for seven days. If there is no fever for three consecutive days, the isolation of such people will be considered over.
According to experts, symptomatic people should remain isolated until they have been free of fever for at least 24 hours.
When Should The Test Be Done After Coming in Contact With The Corona Infected?
Experts believe that people who show symptoms of corona should get tested immediately.
Experts have advised that instead of getting the rapid antigen test done at home, you should get the RT-PCR test done in the lab if you have symptoms of the corona.
Actually, the tests done in the lab are much more sensitive in detecting the virus. The RT-PCR test has the ability to detect the virus within three days of coming in contact with an infected person.
On the other hand, considering the risk of a person getting infected quickly by Omicron BF.7, when should he get the corona test done? Regarding this, Dr. Amy Karger of the University of Minnesota Medical School says that people should get tested three to five days after coming in contact with an infected person.
They say that if you have done one test then you should wait for at least five days before getting the second test done.
