COVID-19 patients in the state are treated in four categories of facilities — severe cases require hospitalisation, moderate cases are admitted to 'health centres' and mild cases are accommodated at 'care centres'. The remaining asymptomatic cases are required to remain in home quarantine. According to a health official, about ten percent of the total active patients in the state need hospitalisation, about 20% need health centres, another 50% need care centres and the rest can go under home quarantine. He also added, "On an average, a patient with severe symptoms requires a bed for about 10 days. This means that a bed will be occupied for 10 days."

The Standard Operating Procedure (SOP) by Health & Family Welfare Department guides the medical staff in the clinical assessment of suspected COVID-19 patients. Any patient arriving with a fever, cough and difficulty in breathing is screened to determine if they are a suspect for COVID-19.

• A patient with severe acute respiratory infection and requiring hospitalization;
• A case for with inconclusive COVID-19 test result.

Once a patient is suspected of COVID-19, their pulse, respiratory rate, blood pressure and oxygen saturation are checked and their samples are collected for testing.{{Cite web|title=TNSOP-6-1-version-1.3|url=https://stopcorona.tn.gov.in/wp-content/uploads/2020/03/TNSOP-6-1-version-1.3.pdf|url-status=live|archive-url=https://web.archive.org/web/20200516091400/https://stopcorona.tn.gov.in/wp-content/uploads/2020/03/TNSOP-6-1-version-1.3.pdf|archive-date=16 May 2020|access-date=19 June 2020|website=stopcorona.tn.gov.in}} The guideline defines mild and moderate-severe as follows:

Mild cases are admitted to standard isolation while moderate to severe are taken to critical care unit (CCU) regardless of the test result. If the results arrive positive, they are treated as per the SOP.

The contacts of the confirmed COVID-19 patients are identified and isolated.{{Cite web|title=TNSOP_3_Contact_follow_up|url=https://stopcorona.tn.gov.in/wp-content/uploads/files/TNSOP_3_Contact_follow_up.pdf|url-status=live|archive-url=https://web.archive.org/web/20200516091358/https://stopcorona.tn.gov.in/wp-content/uploads/files/TNSOP_3_Contact_follow_up.pdf|archive-date=16 May 2020|access-date=19 June 2020|website=stopcorona.tn.gov.in}}

A contact is someone who had either provided direct care without proper personal protective equipment (PPE) for a COVID-19 patient; stayed in the same close environment of a COVID-19 patient (including workplace, classroom, household, gatherings) or travelled in close proximity (1 m) with a symptomatic person who later tested positive for COVID-19. The contacts are classified into two based on the following:

High risk-contacts are tested within 5–14 days of coming into contact. Others undergo testing if they develop symptoms. If they don't develop symptoms, they are cleared to leave isolation after 28 days.

Drugs are given only after confirmation of the lab tests. The drugs used in the treatment of mild COVID-19 cases are Paracetamol, Oseltamavir 150 mg and antibiotics if needed. Their vitals are monitored twice a day.

For moderate to severe COVID-19 cases in CCUs, the following drugs are used:

• Azithromycin 500 mg, once daily for five days;
• Hydroxychloroquine 400 mg on day 1 followed by 200 mg, twice daily for four days (under close medical supervision with monitoring for side effects including QTc interval);
• Omeprazole 40 mg, twice daily for five days;
• Ondansetron 4 mg, twice daily for five days;
• Zinc and Vitamin C supplements;
• Paracetamol 500 mg, three times a day.
• O2 supplementation given to maintain SpO2 more than 94%

Patient's vitals are monitored closely. They are also given a nutritious diet and mental health counseling. If their condition worsens, they are shifted to intensive care unit. A patient is discharged once they are clinically stable and two of their samples taken 24 hours apart test negative.
