The U.S. space agency's announcement comes after the European Space Agency and Russian space agency Roscosmos said they would back its upcoming ExoMars mission, which had also been scheduled for July 2020.
"We have made a hard but well-considered decision to postpone the launch to 2022", Roscosmos CEO Dmitry Rogozin said in a statement.
Rogozin said agencies needed to "maximise the robustness of all ExoMars systems", but also that European experts involved in the project had no ability to travel to "partner industries" because of the "exacerbation of the epidemiological situation in Europe".
The global death toll from COVID-19 has surpassed 4,600, with over 124,500 confirmed cases, according to the World Health Organization, which has declared the situation a "global pandemic".
"We want to make ourselves 100% sure of a successful mission", said ESA Director General Jan Woerner.
"But of course now, in this situation, we see that the coronavirus has also an impact on the preparation, because people from different places of industry in Russian Federation, in Italy and France can not move easily as in the past, so therefore there is also an impact".
To day, all trip equipment required for the launch of ExoMars has actually been incorporated in the spacecraft.
The postponement is another setback for the ExoMars program after the 2016 launch of an orbiter and a test lander.

The descent component has actually been undertaking propulsion system certification in the previous month.
Meanwhile, the descent module and landing platform have been undergoing environmental testing in Cannes, France, to confirm the spacecraft is ready to endure the harsh conditions of space on its journey to Mars.
The new schedule foresees a launch between August and October 2022.
The rover's key feature is the ability to drill down two meters below the Martian surface, a depth at which liquid water is more likely to be found and which would be somewhat shielded from the harsh radiation that bathes the Martian surface.
Spacecraft can only be launched to Mars every two years, to take advantage of the best possible lineup between Earth and its neighbouring planet.
Despite the ongoing coronavirus pandemic, NASA said it now has no plans to push back the launch of its Perseverance rover to Mars, Fox News has learned.
The launch of the ExoMars mission has been delayed from 2020 to 2022 for proving coronavirus issues and concerns.
Three other Mars missions are planned for this summer.
