The document outlines Quezon City's disease surveillance and contact tracing system for COVID-19. It describes data sources, the data management process, contact tracing conducted by health centers, and workplace surveillance. Key aspects of the system include identifying suspected, probable and confirmed COVID-19 cases; classifying case severity; performing initial contact tracing in schools; and notifying the Epidemiology and Surveillance Unit to initiate full contact tracing and case management through local health centers. The goal is to allow early detection and control of COVID-19 transmission through coordinated public health surveillance and response.

7. SARS-CORONAVIRUS 2
• Coronaviruses (CoVs) are a large number
of viruses
✓ You need a powerful microscopes to see
them
✓ “Corona” means crown
SARS-CORONAVIRUS 2

8. SARS-CORONAVIRUS 2
• This is the third coronavirus to have done
so since 2002
✓ Severe Acute Respiratory Syndrome
(SARS) CoV emerged in Guangdong, China,
in 2002.
✓ Middle Eastern Respiratory Syndrome
(MERS) CoV emerged in the Middle east in
2012
✓ SARS Cov 2 emerged in Wuhan, China in
2019
SARS-CORONAVIRUS 2

9. SARS-CORONAVIRUS 2
• The virus primarily spreads between
people through close contact and via
aerosols and respiratory droplets that are
exhaled when talking, breathing, or
otherwise exhaling, as well as those
produced from coughs or sneezes.
• The World Health Organization (WHO)
on March 11, 2020, has declared the novel
coronavirus (COVID-19) outbreak a global
pandemic
SARS-CORONAVIRUS 2

10. SARS-CORONAVIRUS 2
• SARS-CoV-2 probably originated in bats.
• They Infect a side range of mammals and
birds
• Special coronaviruses have jumped species
and can be transmitted between people.
• Bats are considered the most likely natural
reservoir of SARS-CoV-2. Differences
between the bat coronavirus and
SARS-CoV-2 suggest that humans may have
been infected via an intermediate host.

11. • Transmission of SARS-CoV-1 and 2 from mammals as
biological carriers to human.

12. • Reorient the School clinic teachers
and safety officers about basics of
Covid-19 and basic contact tracing
• Shift to an electronic information
system for better information
sharing (TKC)
• To Utilize TKC as a self reporting
tool in monitoring health status of
school staff, teachers and
students
OBJECTIVES:

13. CASE
DETECTION
AND CONTACT
TRACING

14. 1. Contact tracing starts with Case detection

15. 1. SUSPECTED CASES
- A suspect case is a person who
meets the clinical and epidemiological
criteria.
TYPES OF PATIENTS

16. ✓ SUSPECTED CASES A suspect case
is a person who meets the clinical

cough OR acute onset of
ANY THREE or MORE of
the ff signs and symptoms
(fever, cough, weakness,
fatigue, headache, myalgia,
sore throat, coryza, dyspnea,
nausea/vomiting, diarrhea,
altered mental status)
EPIDEMILOGICAL CRITERIA
• Residing or working in an area with
high-risk of transmission (closed
settings) OR health settings anytime
within the 14 days prior to symptom
onset
• Travel to area with community
transmission anytime within the 14

illness

17. TYPES OF PATIENTS
2. PROBABLE CASES
A probable case meets the following
definitions:

criteria AND is a contact of a
probable or confirmed case, or
epidemiologically linked to a
cluster of cases with at least one
confirmed case within the cluster.

to the virus, with the objective of monitoring
their symptoms and ensuring early detection
of cases (MC No. 2020-0020)

touching it
INFECTIOUS RESPIRATORY
DROPLETS AND AEROSOLS
