Following the safety precautions of social distancing, avoiding handshake, crowded places etc. Is the virus present in sweat, tears, saliva and other body fluids and secretions. If yes, for how long can the virus survive in fluids such as sweat, saliva, tears. Will the virus remain active and infectious in this fluids if the carriers is dead and for how long. If No, how can someone contract the virus via handshake?
NO EVIDENCE OF INFECTION TRANSMISSION BY TEARS OR EYE SECRETIONS FROM COVID-19 PATIENTS
There have been hypotheses of SARS-CoV-2 transmission from tears and conjunctival secretions (1-2) but to date there has been no documented evidence in studies to prove these in COVID-19 patients (3-5).

Infectivity period of COVID-19 from secretions.
According to CDC guidance (1):
"SARS-CoV-2 RNA has been detected in upper and lower respiratory tract specimens, and SARS-CoV-2 virus has been isolated from upper respiratory tract specimens and bronchoalveolar lavage fluid. SARS-CoV-2 RNA has been detected in blood and stool specimens, and SARS-CoV-2 virus has been isolated in cell culture from the stool of some patients, including a patient with pneumonia 15 days after symptom onset. The duration of SARS-CoV-2 RNA detection in upper and lower respiratory tract specimens and in extrapulmonary specimens is not yet known but may be several weeks or longer."
Viral shedding in a women for as long as 60 DAYS has been described (2), however, the potential to transmit infection in a COVID-19 patient who clinically and radiologically improves, probably becomes non-infection starting from 2nd week of the illness once SARS-CoV-2 specific antibodies are detected (3).

Other than respiratory droplets SARS-CoV2 is so far detected in urine, tears, conjunctival secretions, feces, anal swabs but not detected in semen, breast milk, vaginal secretions, amniotic fluids. Further researches are required to reach a conclusion.
