The novel coronavirus, SARS-CoV-2, has caused a global pandemic with many unanswered questions. One of the most pressing questions is how long can COVID-19 patients remain infectious? Understanding the period of transmissibility is key to helping prevent further spread of the virus and controlling the pandemic. This article explores the long-term transmissibility of COVID-19 patients and understanding the infectiousness of patients.
Long-Term Transmissibility of COVID-19
The duration of infectiousness of COVID-19 patients is an important factor in controlling the pandemic. The World Health Organization (WHO) states that patients may remain infectious for up to two weeks after the onset of symptoms. However, recent research suggests that the infectious period may be longer.
Studies have shown that patients may remain infectious for up to four weeks after symptom onset. The infectious period may be even longer for patients who are asymptomatic or have mild symptoms. Studies have found that asymptomatic and mildly symptomatic patients can remain infectious for up to five weeks.
In addition, some studies have shown that patients may remain infectious for even longer periods of time. For example, one study found that some patients could remain infectious for up to eight weeks after symptom onset.
Understanding Infectiousness of Patients
In addition to understanding the duration of infectiousness, it is important to understand the level of infectiousness of COVID-19 patients. Studies have shown that the level of infectiousness of a patient is determined by the amount of virus they are shedding.
Patients with more severe symptoms tend to shed more virus and are more likely to be contagious than those with milder symptoms. Similarly, asymptomatic and mildly symptomatic patients may shed less virus and be less contagious than those with more severe symptoms.
Furthermore, the level of infectiousness of a patient may also depend on the amount of time they have been infected. Patients who have been infected for longer periods of time may be more likely to be contagious than those who have only recently been infected.
The long-term transmissibility of COVID-19 patients is an important factor in controlling the pandemic. Studies have shown that patients may remain infectious for up to four weeks after symptom onset and even longer for asymptomatic or mildly symptomatic patients.

As the number of COVID-19 cases worldwide continues to climb, one of the main questions many people have is, how long can COVID-19 patients be potentially contagious? Knowing the answer to this question is important in order to protect ourselves and our families from contracting the virus.
A recent study published in the New England Journal of Medicine found that individuals with COVID-19 can remain contagious for up to 20 days following the onset of symptoms. On average, researchers concluded that meals remained contagious for between 10 and 20 days after the onset of symptoms. This only applies to those who are already displaying symptoms, and not those who are asymptomatic carriers.
When it comes to transmission, the most contagious period appears to be the first week following symptom onset. During this time, patients are more likely to spread the virus and precautions should be taken to limit contact with those who are displaying symptoms. The period from day seven to day twenty is still considered a contagious period but the risk of transmission is lower.
In addition to the period of contagiousness, it is important to note that COVID-19 patients can also be contagious for a period of time prior to displaying any symptoms. Many studies have found that pre-symptomatic patients can spread the virus before any symptoms appear. This means that it is still important to practice social distancing and wear masks even if you are not displaying any symptoms.
Overall, it is important to be aware of how long COVID-19 patients can remain contagious. Knowing this can help us stay safe and limit the chances of transmitting the virus to others.
