Here we go again. After nearly a month, the Department of Health has announced two new confirmed cases of COVID-19. Both are Filipinos. These are the first instances of locals being diagnosed in the Philippines. Here is a closer look at the cases as reported in the DOH press release.

[Update: COVID-19 Cases in the Philippines Now Up to 10]

Case 1

A 48-year-old male Filipino who recently traveled to Japan. He came home on February 25 and developed chills and fever on March 3. He was seen at a hospital and samples were collected for SARS-CoV-2 testing which came back positive on March 5. He is stable and is admitted at the Research Institute for Tropical Medicine.

While we do not have a travel ban to Japan, it does have sustained community-based transmission. This is likely why he was tested after he returned. It does not mean he definitely got this from Japan. To prove that, we will need to compare viral genetic sequences. DOH will do home quarantine of his close contactspeople in his household and anyone else who spent a significant amount of time within 3 to 6 feet of the patient. If any of these contacts develop symptoms, they will be considered persons under investigation (PUIs) and will be admitted and tested.

Case 2

A 62-year-old male Filipino with diabetes and hypertension. He developed a productive cough on February 25. He was seen in a hospital in Metro Manila on March 1 and was admitted with severe pneumonia. A specimen was collected on March 4 and came back positive for SARS-CoV-2 on March 5. He supposedly has no history of travel outside of the country.

This case is much more worrisome. If he did not travel outside the country, this makes it a potential community-level transmission. Even though he does not fit the profile of someone who is routinely tested by DOH, testing was done because he had severe pneumonia and his doctor decided there were enough elements in his case to justify testing. There is a simultaneous surveillance system that DOH has in place called SARI surveillance (Severe Acute Respiratory Infection). This system investigates unexplained severe pneumonia and clustering of these cases. SARI surveillance is meant to detect respiratory infections that may be missed by usual monitoring.

In this case, it complements the travel-based testing protocol of DOH in case some cases do make it to the community. As far as we know, 20% of COVID-19 cases will need hospitalization. Therefore, if there is an outbreak at the community level, there will be a significant increase in hospital admissions. This can be detected by SARI surveillance.

This is a good time to review our basics on COVID-19:

  1. COVID-19 is the disease, the virus is called SARS-CoV-2.
  2. Most people will recover, the current mortality rate is anywhere from 1 to 3%.
  3. Older people and those with chronic illnesses are at higher risk. People above 60 years old have the highest risk of dying and should avoid exposure to this disease.
  4. Get your flu shot.
  5. Wash your hands.
  6. If you are sick, wear a surgical mask.
  7. Stay at home if you are sick unless you need to see the doctor or you need to be hospitalized.
  8. Avoid unnecessary travel.
  9. Avoid crowds.
  10. Follow instructions. If you were exposed, stick to the 14-day quarantine.

There is a lot of anxiety now that we have new confirmed cases. With the increase in COVID-19 patients reported in many countries, it really was just a matter of time before we got a second helping. We can’t close ourselves from the rest of the world, and we can’t perfectly isolate everyone at home. 

WHO has stated the Philippines did a good job containing the first wave. We may be able to contain it again. It will entail even more sacrifices for our healthcare workers. Some are already quarantined after they took care of the two new cases. Please do your part by staying up to date, following instructions, and minimizing your risk.
