The timeline of the duncan case is indicative of the life cycle of the ebola virus. References this page was.
The viral life cycle is dependent on a host cell.
Virus life cycle time. People can carry the virus to others without ever developing symptoms. A virus will remain dormant until it is able to infect the next host activate and replicate. A virus is not able to replicate on its own or use raw materials on which to survive.
I know this can be a stressful time. Some viruses can live in an open place for a short time in some cases only a few hours. We also know the virus can live for hours in the air and several days on surfaces it is up to all of us to stay home as much as possible to help stop the spread and contain covid 19.
The life cycle of a virus is the same as other pathogens. However the only difference is that this life cycle takes a little more time because the virus will take its time before infecting the host cell. They can often survive outside a host for long periods of time.
These viral infections can be much more serious in the older population because their immune system is usually not as strong as it used to be and it cannot fight off the viral infection as quickly. When they do infect a suitable host cell or cells they replicate. Life cycle process viral entry for the virus to reproduce and thereby establish infection it must enter cells of the host organism and use those cells materials.
During this time the virus does not produce any progeny it remains inactive until external stimuli such as light or stress prompts it to activate. These life cycles usually repeat themselves and the viral infection can last anywhere from several days to several weeks to even a lifetime. Nine days passed between duncan s exposure to the virus infection and the appearance of his symptoms.
This corresponds in part to the eclipse period in the growth of the virus population. If you have questions or concerns we are here for you. The incubation time for ebola ranges from 2 days to 21 days.
Some strains of coronavirus live for only a few minutes on paper while others live for up to 5 days. The length of time varies.
