First COVID-19 infections in the Philippines: a case report

Area of Science:

• Epidemiology
• Infectious Diseases
• Public Health

Background:

• The novel coronavirus (COVID-19) pandemic emerged globally, with the first suspected case in the Philippines investigated on January 22, 2020.
• By March 1, 633 suspected cases were reported in the Philippines.
• This report details the initial confirmed COVID-19 cases in the Philippines.

Observation:

• The first confirmed COVID-19 cases involved a young, healthy Chinese couple vacationing in the Philippines in January 2020.
• Patient 1 (female, 39) presented with cough and sore throat, testing positive for SARS-CoV-2, influenza B, and other pathogens; she recovered and was discharged.
• Patient 2 (male, 44) developed fever, cough, and chills, with positive tests for SARS-CoV-2, influenza B, and Streptococcus pneumoniae; he required intubation for worsening pneumonia and became the first COVID-19 death outside China.

Findings:

• Initial nasopharyngeal/oropharyngeal swabs detected multiple pathogens in both patients, including influenza B.
• SARS-CoV-2 was confirmed via PCR on initial swabs for both individuals.
• Despite similar exposure and no significant past medical history, the patients exhibited vastly different clinical trajectories.

Implications:

• COVID-19 (Coronavirus Disease 2019) can manifest with a wide spectrum of clinical severity, even in young, healthy adults.
• This case report emphasizes the critical need for ongoing vigilance and robust public health surveillance to detect and manage emerging infectious diseases.
• Early identification and isolation of cases are crucial for controlling the spread of novel respiratory viruses like SARS-CoV-2.
