The diversity of human viruses is vast and continually expanding. As of now, there are 219 known species of viruses that can infect humans. This number continues to grow with three to four new species being discovered every year. The human virome is not stable and may change over time. In fact, new viruses are discovered constantly.
According to the CDC, some infants and people with immunocompromise could keep spreading the virus for as long as four weeks after they stop having symptoms. As for the common cold, there are over ...
[19] [20] [21] The morbidity and mortality of TB and HIV/AIDS have been closely linked, known as "TB/HIV syndemic".

The most similar known viruses to SARS-CoV-2 include bat coronaviruses RpYN06 with 94.5% identity, [15] and RmYN02 with 93% identity [18] RaTG13 was not the direct progenitor of SARS-CoV-2. [19] Temmam et al. found no serological evidence for exposure to BANAL-52 among bat handlers and guano collectors in the area of Laos where it was sampled ...
People who are asymptomatic do not show symptoms but still are able to transmit the virus. [12] At least a third of the people who are infected with the virus do not develop noticeable symptoms at any point in time. [28] [29] [30] Asymptomatic carriers tend not to get tested. [30] [31] [32]
